Edition 04/2009
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
The adhesion surfaces must be dry, free of oil, dust, grease and any other impurities.
Adhesion is improved if the contact surfaces are roughened with a sanding pad.
  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.
