Coating process: production process of polyester polyurethane optical fiber coating

Core tips: production process: The coating formula of polyester type polyurethane optical fiber coating is as follows: Paint Institute → paint formula → paint formula of polyester polyurethane optical fiber coating The production process of polyester polyurethane optical fiber coating is as follows: Poly (tetramethylene ether glycol) reacted with toluene diisocyanate at 70 ℃ for 2 h, then hydroxyethyl acrylate was added, and then reacted at 70 ℃ for 2 h, then cooled to get oligomer Add isodecyl acrylate and benzyldimethylketal and stir well Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: production process: for the coating formula of polyester polyurethane optical fiber coating, please refer to the following contents: → coating College → coating formula → coating formula of polyester polyurethane optical fiber coating production process of polyester polyurethane optical fiber coating is as follows: the reaction of polyethylene tetramethylene ether glycol and toluene diisocyanate at 70 ℃ 2 h Then hydroxyethyl acrylate was added and reacted at 70 ℃ for 2 h, then cooled to get oligomer The polyester type polyurethane optical fiber coating was prepared by adding isodecyl acrylate and benzyl Dimethylketal and stirring well Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
