BUS-PRIME™ is a Transparent White, Elastomeric Acrylic Waterproofing Adhesive, Bus & Recreational Vehicle Roof Primer Sealer. It is a waterborne high resin content formula that contains no fillers so that it provides waterproofing and excellent adhesion to most any surface.
BUS-PRIME™ is designed as the Primer Sealer for the BUS-KOTE™ Vehicle Roof Coating System. This easy to apply Bus and Roof Coating System will provide many years of durable protection and outstanding beauty.
BUS-PRIME™ rejuvenates, revitalizes, restores, and strengthens the surface to which it is applied. A high resin content, plus the addition of special adhesive chemicals, enables it to bond and seal the roof surface together preparing it for the application of BUS-KOTE™.
Excellent penetrating characteristics enable BUS-PRIME™ to permeate into the substrate providing a permanent bond to the finish coat. On non-porous substrates, the high resin content provides excellent adhesion to the surface forming a tight bond to the finish coat.
