BD 3 Spray is a non-staining, high-tack, water-resistant synthetic lubricant and belt conditioner designed to enhance grip and prevent slippage on all types of belts such as flat, round, and V-belts. It improves traction, reduces squeaking or squealing, and extends belt life by preventing wear, cracking, and glazing. The formula also restores flexibility to worn belts, maintaining their resilience and performance.
