What is Inside Tire Paint and why is it used?

Inside tire paints are applied to the inner-liner of uncured tires to provide the necessary slip required to allow the curing bladder (membrane) to locate easily inside the uncured tire during the shaping process of the curing cycle. High slip at this point of the process aids the bladder to conform to the contour of the inside of the tire, thus ensuring a well-centered tire. These paints also assist in the elimination of trapped air. Their use is important in ensuring minimal curing defect levels and optimum tire uniformity. At the end of the curing cycle inside tire paints provide the effective release needed to remove the tire from the bladder.
