Crosslinking agent UN - 7038 is more than a kind of isocyanate crosslinking agent, can react with amino and hydroxyl groups in the polymer. In most cases, per mole of Moore's UN - 7038 reactions such as hydroxyl group and can obtain the best effect. General addition amount for 1-5%, some system can be added to the 10 to 30%, according to the demand to try. Heat treatment temperature shall be above 100 ℃, the best temperature 160 ℃, usually get crosslinking effect 20 ~ 30 minutes. Add a certain amount of organotin catalyst, can shorten the crosslinking time, the higher the temperature the shorter the processing time.
Ewan chemical product launches adhesion promoter UN - 7038. UN - 7038 is a kind of water dispersible enclosed isocyanate, can be used for crosslinking agent of one-component waterborne coating. Used in water-borne acrylic and polyurethane coating, adhesive as promoting agent and crosslinking agent. Improve the bonding strength of coating, waterproof, abrasion resistance, scrub resistance, scratching resistance and chemical resistance. Can also be added to the polymer system, such as acrylic resin, polyester, epoxy resin and polyurethane resin and so on, in order to enhance chemical resistance and weatherability of the coating.
