Appli­ca­tion

Low vis­cos­i­ty silanol flu­ids are employed as filler treat­ments and­struc­ture con­trol addi­tives in sil­i­cone rub­ber compounding.Intermediate vis­cos­i­ty, 1000-10,000 cSt. flu­ids can be applied totex­tiles as durable fab­ric soft­en­ers. High vis­cos­i­ty silanolter­mi­nat­ed flu­ids form the matrix­com­po­nent in tack­i­fiers and pres­sure sen­si­tive adhe­sives.
It is a low mol­e­c­u­lar weight poly­di­methyl­silox­ane ter­mi­nat­ed with a sil­i­con hydrox­yl group and is a low vis­cos­i­ty hydroxy sil­i­cone oil.
A large num­ber of amino sil­i­cone oils are used for the pro­duc­tion of aminosil­i­cone oils. The con­ver­sion per pass can reach over 99%. Due to the pres­ence of active hydrox­yl groups, the aminosil­i­cone oil can be used to pro­duce direc­tion­al adsorp­tion of car­boxyl groups on the sur­face of fab­rics, result­ing in a sig­nif­i­cant decrease in the coef­fi­cient of fric­tion between fibers. As a result, the soft­ness and smooth­ness of the fab­ric are sig­nif­i­cant­ly improved, and its wash­ing resis­tance can be improved. The amino sil­i­cone oil pro­duced by the lin­ear body not only has all the prop­er­ties of the amino sil­i­cone oil, but also has an affin­i­ty with the emul­si­fi­er for pro-mar­itime con­t­a­m­i­na­tion and lipophilic groups, the emul­sion is eas­i­ly emul­si­fied, the dis­per­sion is good, the emul­sion trans­paren­cy is good, and the par­ti­cle size is small.
