Polyurethane Adhesive Sealant

Definition:

  • Polyurethane Adhesive Sealant -AKD 476 KD5 05-

Product Description

Polyurethane Adhesive Sealant -AKD 476 KD5 05- is a paste-like, one-part adhesive sealing material with a polyurethane basis which forms a rubbery/elastic material when it hardens.

The film formation and hardening time depends on the humidity and temperature. The hardening time is also affected by the joint depth.

These times can be shortened by raising the temperature and humidity. Lower temperature and humidity levels delay the hardening.

Properties:

  • Can be painted over, even "wet-in-wet"
  • Very fast drying
  • Levels out slightly on the surface
  • Excellent elasticity
  • High resistance to aging
  • Can be sanded
  • Can be spread

Application Instructions

Application

  • Polyurethane Adhesive Sealant -AKD 476 KD5 05- is used for elastic sealing/adhesion, especially for sealing welds and sealing very narrow joints where its lack of stability is of no consequence in the following areas: body and vehicle assembly as well as vehicle add-ons, especially if the sealant is to be painted. To avoid yellowing or cracking, the material should always be painted over when used on the outside seams.
  • The use of Polyurethane Adhesive Sealant -AKD 476 KD5 05- means that mechanical securing methods such as bolting, welding and clamping can be partially omitted. Until the sealing/adhesive has hardened, the parts should be temporarily fixed in position with adhesive tapes and spacers.
  • The Polyurethane Adhesive Sealant -AKD 476 KD5 05- has the major advantage of being both an adhesive and a sealant.
  • The material is suitable only to a limited extent for some adhesive purposes in vehicle construction.

Adhesive Characteristics

  • The Polyurethane Adhesive Sealant -AKD 476 KD5 05- provides good adhesion without glass-/paint primer on primed and painted bodywork, on wood (untreated, glazed and painted), some plastics such as PBTP, polyurethane hard foam and GF polyester.
  • Depending on the base surface it may be necessary to use a glass-/paint primer as an adhesion agent to achieve an optimum adhesion.
  • On account of the large number of primers, paints and differing plastic surfaces etc., it is recommended to conduct an application-specific test beforehand.
  • Careful cleaning on plastic and metal surfaces with a suitable solvent often results in significantly better adhesion.

Note

  • Before starting to apply, it is necessary to read the safety measures and advice in the safety data sheet.
  • Even for products which are not required to be labeled by law, the usual safety measures must be observed for chemical emissions.

Processing

Note

Body areas and adhesion surfaces that are to be sealed must be insulated with a Two-Part Filler before applying the material.

  • The adhesion surfaces must be dry, free of oil, dust, grease and any other impurities. Cleaners A, D and Plastic Cleaner -D 195 850 A1- are suitable for cleaning.
  • The application of Polyurethane Adhesive Sealant -AKD 476 KD5 05- from a 310 ml nozzle cartridge is done with a manual or compressed air guns. The 310 mL foil cartridges are used with the Cartridge Gun -VAG1628- or the Pneumatic Cartridge Gun -VAG1761/1-. A pressure of 2 to 5 bar is required for compressed air application.
  • Low material temperatures of the sealant increase its viscosity. This results in a lower spraying rate. To prevent this the sealant should be brought to the correct temperature in the appropriate manner before processing begins.
  • If the base surface is too cold, condensation can form if the temperature is lower than the dew point. This should be avoided by heating the base surface beforehand.
  • After processing, the Polyurethane Adhesive Sealant -AKD 476 KD5 05- can be smoothed with a jointer or a spatula which have been moistened with low surface tension water. If the edges of the joint are masked with tape, simply pull off the tape with a spatula.
  • It is recommended to use cleaner D to remove any unhardened adhesive sealing material from the tools.

Painting procedure

  • The Polyurethane Adhesive Sealant -AKD 476 KD5 05- can be painted over using the "wet-in-wet" process with one-part and two-part repair paint with an alkyd resin-acrylic base as well as with all original repair paints.
  • Nitro repair paints out of a spray can and paints, paint thinners and catalysts with alcohol content are not compatible with the adhesive sealing material (no hardening).
  • Corrosion protection primers may only be applied to hardened material as they are strongly hindered in most cases by steam diffusion.
  • If drying is accelerated by the use of a drying oven or an IR dryer radiator, a pre-reaction/waiting time of at least 30 minutes must be adhered to. Only then is the painted over adhesive sealing material to be warmed. The maximum permissible temperature for non-hardened material is +90 ºC (194 ºF) for one hour.

Incompatibility

  • Polyurethane Adhesive Sealant -AKD 476 KD5 05- does not adhere to sealants that have a MS polymer and silane-modified polymer base.
  • On the other hand, if the hardened Polyurethane Adhesive Sealant -AKD 476 KD5 05- is processed on MS-polymerer and silane-modified polymer base, then there is good adhesion.

Sprayable Sealant

Definition:

  • Sprayable Sealant -D 476 KD1 M2-, gray
  • Sprayable Sealant -D 476 KD2 M2-, black

Product Description

Sprayable Sealant -D 476 KD1 M2-/- D 476 KD2 M2- is a spray-on sealant with a MS polymer base. It hardens into a rubber-elastic material with good abrasion resistance by absorbing atmospheric moisture.

The film formation and hardening time depends on the humidity and temperature. The hardening time is also affected by the layer thickness.

These times can be shortened by raising the temperature and humidity. Lower temperature and humidity levels delay the hardening.

Properties:

  • Sealant and weld sealant in one product
  • High stability
  • Can be sprayed and brushed
  • Can be painted over with conventional or water-based paints up to three days after applying
  • Adheres to many materials without glass-/paint primer
  • High initial strength
  • Can be spot welded
  • Silicone-free
  • No strong odor
  • Isocyanate-free
  • Quick drying
  • UV resistant
  • High resistance to aging
  • Sound-dampening properties

Application Instructions

Application

  • Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2- is used to seal welds in vehicle repair which have been sprayed at the factory, for example in the engine, luggage, and passenger compartment areas. Application tools (telescope spray gun or Pneumatic Cartridge Gun -VAG1761/1-) can be used to reach every desired weld.
  • The material is used as a surface coating to repair or supplement PVC underbody coating or stone chip protection.

Pretreatment

  • The adhesion surfaces must be dry, free of oil, dust, grease and any other impurities. Cleaner FL is suitable to clean with.
  • Adhesion is improved if the contact surfaces are roughened with a sanding pad.
  • If the material is painted over after completely drying, then the painting preparatory work similar to the plastic preparatory work is to be followed.

Note

Before starting to apply, it is necessary to read the safety measures and advice in the safety data sheet.

Even for products which are not required to be labeled by law, the usual safety measures must be observed for chemical emissions.

Processing

Note

Body areas and adhesion surfaces that are to be sealed must be insulated with a Two-Part Filler before applying the material.

  • Applying Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2- from 310 mL aluminum cartridges can only be performed with the telescope spray gun or Pneumatic Cartridge Gun -VAG1761/1-. These application devices make is possible to apply the material as a strip of material (sealant bead) or to spray it on by using the dual-circuit air system.
  • The material can be both sprayed and brushed on. This means that it is possible to imitate textured bonds and brushed structures.
  • The sealed seams can be painted over as early as 15 to 30 minutes.
  • The corresponding settings on the application devices enable the operator to imitate all textures specified by the manufacturer quickly and conveniently. The spraying distance can be used to vary the width and limit of the bond. Refer to the operating instructions for details on handling and setting the spray gun.
  • It is recommended to remove any unhardened sealant from the tools using cleaner FL. Hardened material can only be removed mechanically.

Painting procedure

  • The Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2- can be painted over with one-part and two-part repair paint and even those containing alcohol as a solvent.
  • Painting over quickly does not prevent complete hardening, it is, however, delayed. Do not wait longer than three days before painting.
  • Before sealing or coating, phosphate and epoxy resin primers are particularly suitable for corrosion protection. It is imperative that the primers are dry before it is applied.
  • If the body area to be painted after an accident repair is still to be coated with filler, filler primer or spray-on filler, these materials must be applied before sealing or coating with Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2-.
  • If a filler still needs to be applied after sealing or coating with Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2-, then the sealant should be at least six hours old and a filler suitable for coating plastic is used.

Incompatibility

  • The Sprayable Sealant -D 476 KD1 M2-/-D 476 KD2 M2- is not compatible with fresh one-part polyurethane material. Polyurethane products must be solidified before they are sprayed with the sealant.
  • The material should not be treated with aromatic solvent systems. As a result, it can partially dissolve or swell the sealant.

  • Adhesive/Sealant -D 511 510 A2-, black

Product Description

Adhesive/Sealant -D 511 500 A2-/-D 511 510 A2- is used in vehicle repair to protect the bodywork repairs against corrosion, as a quick-hardening sealant for all visible and invisible seams and dents and also to patch up PVC sealed welds.

The Adhesive/Sealant is highly suitable as a sealant in spot welding between spot welded flanges to prevent corrosion.

Properties:
  • High adhesive properties on bare, primed and painted metal, galvanized surfaces, aluminum, wood, glass and all conventional plastics used in vehicles.
  • Can be painted immediately
  • Can be dried with an IR dryer
  • Dries quickly under the paint
  • Possible to weld and spot weld
  • Does not form bubbles
  • No contact-corrosion on zinc or aluminum
  • Exceptional corrosion protection
  • Solvent-free and contains no isocyanate and PVC
  • Very good UV- and aging resistance

Application Instructions

Application

  • Adhesive/Sealant -D 511 500 A2-/-D 511 510 A2- is used to seal welds in vehicle repair.

Pretreatment

Note

Before starting to apply, it is necessary to read the safety measures and advice in the safety data sheet.

Even for products which are not required to be labeled by law, the usual safety measures must be observed for chemical emissions.

Processing

Note

Body areas and adhesion surfaces that are to be sealed must be insulated with a Two-Part Filler before applying the material.

  • Adhesive/Sealant -D 511 500 A2-/-D 511 510 A2- is applied to seal welds and impacts using the Pneumatic Cartridge Gun -VAG1761/1-, or the Cartridge Gun -VAG1628-. Then, depending on its appearance, it is to be left as a sealant bead or evened with a brush or spatula (observe the hardening time < 10 minutes). After a film has formed, the material can still be smoothed further with a moist spatula.
  • The Adhesive/Sealant can be painted over with all repair paints. Painting must ensue within 48 hours of the sealant being applied. Drying the paint with an infra-red dryer does not hinder the hardening of the sealant.
  • If the Adhesive/Sealant is used as a sealant during spot welding, then a sealant bead (2 to 3 mm diameter) is to be applied to the flange before the repair part is attached. The repair part should be spot-welded before a sealant film forms (< 10 minutes)
  • The material can be spot-welded within 30 minutes. After welding, the sealant that has emerged can be smoothed.

Incompatibility

  • Never apply any sealants with a MS polymer and silane-modified polymer base to an unhardened polyurethane adhesive sealant. The polyurethane adhesive/sealant will not adhere properly or only partially.
  • However, a hardened polyurethane adhesive/sealant adheres well to fresh, spray-on sealants with a MS polymer and silane-modified polymer base.
