| Product Information: Addolink TR Schuppen is used at low ratios only (about 2 - 10%, calculated on the total addition of crosslinking agent). Addolink TR Schuppen is miscible with Addolink B and Addolink R at all ratios. The reaction between Addolink TR Schuppen and polyisocyanates leads to three-dimensional crosslinking of the hard segment material; this reduces the segregation of the hard and soft segments in the elastomer. This effect can be utilized to reduce the Shore hardness of soft elastomers. It also improves their resistance to swelling, but reduces their tear strength. In hard elastomers it reduces shrinkage phenomena and stress cracking. Function: Crosslinking agent for polyurethane elastomers (hot- and cold-curing cast systems).
