Addolink® 1604 is an aromatic diamine. Used as a crosslinking agent in combination with prepolymers for the manufacture of high-quality heat curing PUR elastomers, giving considerably longer casting times than other amine crosslinking agents. If protected from moisture, it has a shelf life of 12 months. Addolink® TR Schuppen is 1.1.1-trimethylol propane. Acts as a crosslinking agent for polyurethane elastomers (hot- and cold-curing cast systems). 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. It has a shelf life of 12 months. Addolink® 110 is an aromatic amine. Acts as a crosslinking agent in combination with prepolymers for the manufacture of PUR elastomers. At temperatures between 20-25 °C, the product has a shelf life of 6 months if protected from moisture. Addolink® 30/10 pastilles is hydroquinone di-(2-hydroxyethyl) ether
(HQEE). Acts as a crosslinking agent for the production of thermoplastic polyurethanes. It is noted for its high degree of purity. Thus reduces undesired side reactions. With Addolink® 30/10 molded parts display a high degree of heat resistance and a low compression set. The product can content some powder cause of it is a brittle material. It has a minimum shelf life of 12 months. Addolink® TR is 1,1,1-trimethylol propane. Acts as a crosslinking agent for polyurethane elastomers (hot- and cold-curing cast systems). The reaction between Addolink® TR and polyisocyanates leads 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. It has a shelf life of 12 months. Addolink® 1708 is a liquid aromatic diamine. Acts as a curative for the manufacturing of polyurethanes or polyurea elastomers. It also functions as a curing agent for advanced epoxy resins. It eliminates air-bubbles and ensure pinhole free surfaces. In transparent systems, it can reduce transparency. It can be used at room temperature and also be used at higher temperatures. It is compatible with most commercially available isocyanate prepolymers. Addolink® 30/10 technical ground is hydroquinone di-(2-hydroxyethyl) ether. Acts as a crosslinking agent for isocyanates crosslinkable polyurethane rubber. It is noted for its high degree of purity. With its use, molded parts display a high degree of heat resistance and a low compression set. It is used in combination with Addolink® TT. The ratio of the two products is 0,57 parts of weight Addolink® 30/10 technical ground to 1 part of weight Addolink® TT. It has a storage life of 12 months. Addolink®R is 1,4-butane diol with special activator. Acts as a crosslinking agent for polyurethane elastomers (hot- and cold-curing cast systems). It has a shelf life of 12 months. Addolink® H is 1,4-butane diol with special retarder. Acts as a crosslinking agent for the production of high modulus polyurethane elastomers (hot-curing cast systems). It is hygroscopic. At a temperature of 20°C, it can be stored for 6 months. Addolink® 0312 is alicyclic diol. Acts as a crosslinker for polyurethane hot-curing cast elastomers. It is used in liquid form and protected from moisture when in use. With its use, cast time is prolonged up to 30 minutes; demolding is possible within one hour.
