Description:

This is a heavy-duty, weather-resistant polyurethane foam specifically engineered for demanding construction, industrial maintenance, and infrastructure repair projects. It delivers industrial-grade adhesion to rigid substrates including concrete, brick, natural stone, PVC, and aluminum alloy, with exceptional gap-filling performance that adapts to irregular joint widths. Featuring enhanced UV resistance and temperature tolerance, it maintains structural integrity in extreme climates (from -30°C to 80°C), ensuring long-term durability against moisture infiltration, thermal expansion, and contraction. Ideal for large-scale curtain wall installation, industrial pipeline insulation, and exterior building envelope sealing.

Features & Benefits:

Closed cell structure: Zero water absorption, high rigidity, and dimensional stability

Superior waterproof & moisture-proof performance: Prevents mold growth and substrate corrosion

High expansion rate (up to 30x): Fills wide gaps (20-100mm) in one application

Fast curing: Tack-free in 10 minutes, fully cured in 24 hours for quick project turnover

Excellent sound dampening & thermal insulation: Reduces energy loss and industrial noise pollution

Strong adhesion to engineering materials: Bonds permanently with concrete, stone, and metal without primers

No shrinkage: Maintains sealing effect for over 10 years

UV-resistant formula: Suitable for outdoor exposed applications

Application:

Large-scale curtain wall installation and structural bonding
Industrial pipeline insulation and anti-corrosion sealing
Sealing of roof joints, expansion cracks, and basement waterproofing projects
Bonding and fixing of heavy-duty insulation boards in industrial workshops
Sealing of gaps between steel structures and building facades
Noise reduction for industrial equipment enclosures
Waterproof sealing of exterior wall penetrations (pipes, cables)
