What This Product Is and How It Works

PU STAR AUTO SEALENT is a polyurethane-based sealant formulated for automotive applications including panel seams, joints, and glass bonding. It is provided as a thick paste in a cartridge and cures when exposed to moisture in the air to form a flexible, rubber-like seal with strong adhesion to metal and other substrates.

The cured elastomer accommodates vibration, thermal movement, and mechanical stresses common in vehicle structures. Polyurethane seals do not sag during application and are suitable for both new assembly and repair work.

Material Quality, Durability and Environmental Performance

This automotive PU sealant offers excellent adhesion to metal, glass, plastics, and painted surfaces found in vehicle body structures. Once cured, it resists water, heat, aging, vibration, and environmental exposure, maintaining elasticity and sealing integrity over time.

Weather-resistance, UV stability, and flexibility are typical performance characteristics of polyurethane automotive sealants, making them suitable for Kenya’s varying climates.

Installation, Handling and Compatibility

Prior to application, joints and surfaces must be dry, clean, and free of oil, grease, rust, or old sealants. Load the cartridge into a caulking or applicator gun, cut the nozzle to the appropriate bead size, and extrude a continuous bead into the joint or gap. Tool the sealant as needed for a neat finish.

Curing begins with exposure to atmospheric moisture; full cure time varies with bead thickness and environmental conditions. Wear protective gloves and eye protection when handling uncured sealant.

Typical Applications in Kenya

PU STAR AUTO SEALENT is commonly used by:

Automotive Workshops & Technicians: Sealing body panel seams, roof joints, and frame interfaces.
Glass Fitters & Auto Body Repair: Bonding and sealing windscreen and side glass in cars, buses, and commercial vehicles.
Maintenance Professionals: Repairing and resealing vehicle joints after collision repair or part replacement.
DIY Automotive Users: Body seam sealing and weatherproofing on pickups, vans, and light vehicles.

Urge compatibility testing for specific substrates, especially where high thermal cycling or structural stress is expected.
