Product Description of WPA Polyurethane Low-Temperature Adhesive
The WPA series polyurethane low-temperature adhesive adopts a two-component thermosetting molding system, free of halogens and volatile solvents. When Component A and Component B are thoroughly mixed in a specific ratio, they undergo a curing reaction to form a flexible and highly tear-resistant cross-linked structure. It boasts excellent thermal cycling stability and mechanical resistance, with an operating temperature range of -196℃ to +100℃.
