GMW GMW3041 PDF

This specification describes the performance requirements and test conditions for polyurethane adhesive sealing compounds and compatible primers. Performance requirements include long and short term testing for approval of new polyurethane systems and short term testing for determining the compatibility of new combinations of approved polyurethane systems to approved body paint or fixed automotive glass. Compatibility to other substrates is not restricted to, but may include RIM, PVC, SMC or TPE.

Material Description.

The material is typically a one component, warm or cold temperature applied, moisture cure, black polyurethane adhesive sealing compound. It is used in conjunction with compatible glass side primers for bonding automotive glass to body openings. Based on compatibility, it may be used with or without a primer for bonding to specific paint systems, plastics or metals.

Symbols.

The material abbreviation according to ISO 11469 is <PUR>.

Typical Applications.

Applications for materials approved to this specification include the bonding and sealing of fixed automotive glass. These are typically windshields, backlites, fixed liftgate, side and encapsulated glass. Materials approved to this requirement are generally intended for bonding the aforementioned automotive glass to painted body openings.
