Adhesive sealer -D 511 500 A2-, grey

Adhesive sealer -D 511 510 A2-, black

Issued 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 and also as a fast-hardening sealant for all visible and invisible joints and dents and also to patch PVC sealing welds.

Adhesive sealant is highly suitable as for preventing corrosion between spot welded flanges

Properties:

Strongly adhesive to bare, primed and painted metal, galvanised surfaces, aluminium, wood, glass and all plastics commonly used in vehicles.

May be overpainted immediately

May be dried with an IR radiant drier

Dries quickly under paint

May be welded or spot-welded through

Does not form bubbles

No contact corrosion on zink or aluminium

Excellent corrosion protection

Solvent-free and contains no isocyanate or PVC

Excellent UV and ageing resistance

Technical data sheet

Application

Adhesive sealant -D 511 500 A2-/-D 511 510 A2- is used to seal seams following accident repairs to vehicles.

Pretreatment

The adhesion surfaces must be dry, free of oil, dust, grease and any other impurities.

Adhesion will be improved if the contact surfaces are slightly roughened using an emory pad.

Note

Before using, read the safety measures and recommendations in the safety data sheet.

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

Application

Note

Areas of the body to be sealed and adhesion surfaces must be isolated using 2-pack surfacer before the material is applied.

Adhesive sealant -D 511 500 A2-/-D 511 510 A2- may be applied to seams and joints using pneumatic cartridge gun -V.A.G 1761/1- or hand cartridge gun -V.A.G 1628-. Then, depending on appearance, leave as sealant bead or smooth it with a brush or filling knife (this must be done before a skin forms, in less than 10 minutes). After a skin has formed, the material can still be smoothed further with a moist filling knife.

Adhesive sealant may be overpainted with all repair paints. Overpainting must ensue within 48 hours of the sealant being applied. Drying the paint with an IR radiant dryer does not hinder the curing of the sealant.

If adhesive sealant is to be used in conjunction with spot welding, apply a bead of sealant (2-3 mm diameter) to the flange before setting repair part in place. The repair part must be spot welded before skin formation begins (< 10 minutes).

The material may be spot welded within 30 minutes. After welding, sealant that has escaped can be smoothed.

Incompatibility

Never apply sealants on MS polymer or silane-modified polymer basis to uncured polyurethane adhesive sealants. The curing of the polyurethane adhesive sealant will be hindered, or will not be complete.

On the othe hand, the adhesion of fresh, sprayable sealants on MS polymer or silane-modified polymer basis to fully cured polyurethane adhesive sealant is good.
