Butyl Windscreen Sealant – High Sticky Adhesive Waterproof Insulation Tape

Butyl windscreen sealant, also known as butyl rubber sealing strip or butyl sealing tape, is a black synthetic butyl rubber sealant. It is commonly used in the installation of automatic windshields, particularly in the sealant tape between the glass and metal areas. This sealant tape has excellent adhesion and weather resistance, and can effectively prevent moisture and air infiltration, thereby maintaining a permanent seal between the glass and metal. In addition, it can withstand temperature changes and UV exposure, ensuring the waterproof performance of the welded joints and extending the vehicle's lifespan.

Precautions

• Before use, please remove moisture, grease, dust, and other dirt from the surface of the adhesive material;
• The tape should be stored in a cool, dry place, avoiding high temperatures, direct sunlight, or rain, and should not be stored on its side;
• The shelf life of the tape in its original packaging is generally 3 years.
• In cold weather conditions, it is best to heat the tape before attempting installation, as this will soften the tape, making it easier to handle.
