What is the density of polyurethane?

The density of polyurethane is1.005g/cm3. Polyurethane is called polyurethane, which is the general name of macromolecular compounds with repeated carbamate groups in the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate with dihydroxy or polyhydroxy compounds.

The advantages of polyurethane waterproof coating are the most common materials in our modern decoration construction. Its environmental adaptability is excellent, and it will solidify when it comes into contact with water and gas in the air, forming a tight protective film. Polyurethane waterproof coating is convenient for construction. It can be directly used on dry or wet surfaces without being affected by other factors, and has excellent coagulation performance.

The internal polymer can easily penetrate into the gap of the base surface, and has strong follow-up. The coating film in polyurethane waterproof coating has excellent tensile properties and good flexibility, even if the base layer cracks or expands, it will not have great influence.
