  • Release agent for tire bladder, tire bladder, and pneumatic tire
    Patent number: 10434685
    Abstract: A release agent for being coated onto a tire bladder made of a zinc-oxide-incorporated butyl rubber during pneumatic-tire molding, the release agent containing (A) organopolysiloxane, which contains a carboxy group indicated by the general formula (1) below (in the formula, R1 is a substituted or unsubstituted C1-C30 monovalent hydrocarbon group excluding R2, R2 is a carboxy-group-substituted C1-C30 monovalent organic group, R3 is R1 or R2, and n is an integer of 3 to 2000.). This release agent produces a longer service life of a tire bladder and leads to reduced tire production cost because the amount of silicone that migrates to the tire side is low when the tire is released, and repeated mold-release performance is enhanced.
