A003PS75 Windshield Polyurethane Adhesive
A003PS75 is a cold applied
windscreen adhesive based on polyurethane, optimized for manual application. It provides a long open time and ensures safe application even under warm conditions. It may be used as a primerless to glass adhesive in auto glass replacement applications. Primerless to glass application requires the glass to be prepared using an Automotive grade glass cleaner, the bonding surfaces must be free of contamination and have sufficient UV protection.
A003PS75 is suitable for experienced professional users only. This product and related process information is designed for Automotive Glass Replacement. For other applications, tests with actual substrates and conditions have to be performed ensuring adhesion and material compatibility.
Features
Easy to extrude with manual application gun
Solvent free, no odor
OEM approved adhesive system
Fast adhesion build up
Primerless to glass adhesion
Typical application
Bonding and sealing of vehicle windshield and side glass replacement;
Low speed electric vehicle glass installation and sealant.

Application process
Cleaning the substrate surface: the substrate surface must be dry and clean, such as, free of dust, grease, asphalt, tar, paint, wax, rust, impermeable agent, curing agent, isolation agent and film, etc. Surface cleaning can be handled by scraping, cutting, grinding, sweeping, washing, wiping, blowing, etc. Note: Glass without ceramic coatings need proper UV protection.
Application:The sealant
can be processed between 5 °C and 40 °C but changes in reactivity and application properties have to be considered. The optimum temperature for substrate and adhesive is between 15 °C and 25 °C.
Consider that the viscosity will increase at low temperature. For easy application, condition the adhesive at ambient temperature prior to use. To ensure a uniform thickness of the bondline it is recommend to apply the adhesive in form of a triangular bead.
The open time is significantly shorter in hot and humid climate. The glass must always be installed within the open time. Never install a glass after the adhesive has built a skin.
Removal: Uncured sealant may be removed from tools and equipment or other suitable solvents. Once cured, the material can only be removed mechanically. Hands and exposed skin have to be washed immediately using hand wipes or a suitable industrial hand cleaner and water. Do not use solvents on skin.
