DKW-4650BL Water-Based Semi-Permanent Tire Bladder Lube

DiamondKote DKW-4650BL is a water based tire bladder coating which promotes release from the tire when used as a primer in conjunction with an inside tire paint such as DiamondKote DKW-4655BL. It reduces bladder buckling and extends bladder life. Diamondkote DKW-4650BL  may also be re-applied to a used bladder to promote release of the green tire. It can also be particularly useful for retread curing envelopes.

Founded as Franklynn Industries, Inc. in 1991 offering DiamondKote, Aqualift, and later added Crystal brands.  Now part of the ITW Pro Brands team.
