Product Overview
Butyl waterproof tape is a permanently non-curing self-adhesive sealing tape manufactured from butyl rubber as the primary raw material, compounded with auxiliary agents via advanced processing. It delivers exceptional adhesion to various substrates while offering superior weather resistance, aging resistance, and waterproofing. This solvent-free product provides permanent sealing, vibration damping, and protective functions without shrinkage or toxic emissions. Its permanent tackiness ensures excellent conformability to substrate thermal expansion/contraction and mechanical deformation.
Key Features
Self-adhesive application: Forms continuous uniform seals without heating or pressure. Conforms perfectly to irregular surfaces.
Chemical resistance: Excellent corrosion protection for metal substrates and cable surfaces.
Permanent flexibility: Maintains elasticity without hardening. Resists tearing while retaining waterproof integrity during movement.
Dual barrier function: Superior waterproofing and vapor sealing performance.
Wide temperature tolerance: Effective across -40°C to 90°C service range.
Applications
Building sealing: Window/door frames, concrete roofs, HVAC ducts
Repairs: Single-sided tape for roof leaks, vehicle body joints
Construction joints: Waterproofing for new roofs, basements, structural expansion joints, polymer membrane overlaps
Infrastructure: Utility box sealing, spray foam perimeter sealing (air/water/damp proofing)
Metal roofing: Sealing for color steel plate overlaps, gutter connections, and light-transmitting panels
Automotive: Panel seam sealing, door/window moisture barrier installation
Specialized: Aluminum foil-backed version for metal roofs, PC panels, and sun-exposed structures
Safety & Handling
Surface prep: Clean substrates of moisture, oil, and debris before application
Storage: Keep in cool/dry conditions away from heat sources, sunlight, and moisture
Installation: Achieve optimal waterproofing by applying correctly in single placement
