BOSS PU 50 Polyurethane Sealant
BOSS PU 50 Polyurethane Sealant is a high-performance, one-component, elastomeric sealant that offers superior flexibility, durability, and adhesion. Formulated for demanding industrial, construction, and automotive applications, this advanced polyurethane sealant provides an exceptional seal that withstands extreme conditions while maintaining its strength and elasticity.
BOSS PU 50 is designed to bond securely to a wide variety of substrates, including concrete, metal, wood, glass, and most plastics, making it ideal for sealing and bonding tasks across multiple industries. Its robust adhesion properties ensure that it forms a tight, long-lasting seal on expansion joints, precast panels, curtain walls, and other surfaces where movement or stress is a factor. The sealant's high elasticity allows it to accommodate thermal expansion and contraction, ensuring that joints remain sealed even in fluctuating temperatures.
BOSS® PU 50 is a fast-curing, one-component, moisture-curing polyurethane adhesive sealant, that turns into a flexible, durable and resistant elastomeric seam and has very good adhesion to most industrial materials.
