BILIN A3 Multi Purpose Polyurethane Foam High Stability No Shrinkage

Description:

This is a heavy-duty, all-weather polyurethane foam tailored for large-scale construction, infrastructure repair, and industrial sealing projects. It boasts industrial-grade adhesion to rigid engineering materials such as reinforced concrete, firebrick, PVC pipes, and aluminum alloy profiles, with outstanding gap-filling capacity that can adapt to irregular joint widths (10–150mm). The formula is enhanced with anti-UV additives and thermal stabilizers, enabling it to withstand extreme climate fluctuations from -40°C to 90°C, while its superior moisture resistance prevents substrate corrosion and mold growth. Ideal for curtain wall installation, industrial pipeline insulation, and exterior building envelope sealing.

Features & Benefits:

Closed cell structure: Zero water absorption, high rigidity, and long-term dimensional stability
Superior waterproof performance: Blocks rainwater and moisture penetration for permanent sealing
Excellent installation compatibility: Works with professional foam guns for precise application
Easy operation: Smooth extrusion without clogging, suitable for both horizontal and vertical gaps
High expansion rate (up to 35x): Fills wide gaps in one single application
Fast curing: Tack-free in 8 minutes, fully cured in 24 hours to shorten construction cycles
Effective sound dampening & thermal insulation: Reduces industrial noise and cuts energy consumption by 30%
Strong adhesion to engineering substrates: Bonds firmly without primers
Exceptional stability: No shrinkage or deformation even under long-term temperature changes
