Polyurethane Windshield Adhesive for Auto Glass Bonding
CHEMPU polyurethane windshield adhesive is designed for bonding windshields and other automotive glass. It forms a strong, flexible seal that helps withstand vehicle vibration, temperature changes and outdoor weather conditions.
The non-sagging formula supports clean application on vertical glass surfaces. Different curing speeds and performance grades are available for passenger cars, buses, trucks and other vehicles.
Car Body Seam Sealant for Automotive Joints and Panels
CHEMPU car body seam sealant is developed for sealing welded joints, overlapping panels and body seams during vehicle manufacturing and repair. It creates a flexible barrier that helps prevent water, dust and moisture from entering vehicle body joints.
Its non-sagging consistency allows controlled application on horizontal and vertical surfaces. After curing, the sealant remains flexible to accommodate vibration and minor movement between metal panels.
RV Roof Sealant for Waterproof Seams and Repairs
CHEMPU RV roof sealant provides a flexible waterproof seal for roof seams, vents, skylights, edge rails and other exterior joints. It is designed to accommodate movement caused by road vibration, temperature changes and regular outdoor exposure.
The sealant helps close gaps around roof accessories and fasteners, reducing the risk of rainwater entering the vehicle. Formulations are available for different application methods and common RV roof materials; substrate compatibility should be confirmed before use.
