BAYPRET® USV is a self-crosslinking polyether polyurethane polymer which forms a permanent highly elastic film around the fibres. This film is formaldehyde-free. Unlike synthetic resins, BAYPRET® USV does not need a catalyst because it is self-crosslinking. If it is used in combination with synthetic resins these should be crosslinked with weak catalysts such as magnesium chloride or aminohydrochloride. BAYPRET® USV may react to strong catalysts such as zinc nitrate or zinc chloride.
