DKW-4655BL Water-Based Semi-Permanent Tire Bladder Lube

DiamondKote DKW-4655BL is a water-based, semi-permanent coating designed to release tires from the curing bladder and maximize bladder life. Its lubricating properties aid in tire centering by allowing the bladder to properly seat against the inner liner during shaping pressure. DiamondKote DKW-4655BL does not contain any filler materials so it reduces buildup and flaking compared to inside tire paint. A cleaner surface promotes air bleed through the venting channels on the bladder and eliminates the particulate on the inside of the tire. DiamondKote DKW-4655BL is built non-hydrogen generating technology that makes it one of the safest products on the market.

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