BxPB Paint Drier (Lead Replacement)
Whatsapp Order
BxPB Paint Drier is a specialized industrial additive designed as a non-toxic, lead-free alternative to traditional lead-based paint driers. It contains 36% active metal content primarily composed of bismuth and other metals, formulated to accelerate the drying and curing process of oil-based paints, varnishes, and coatings. The product improves film formation, reduces drying times, and enhances the durability and gloss of finished surfaces without the health and environmental hazards associated with lead compounds. BxPB36% Paint Drier is commonly used in architectural, industrial, and automotive coatings as a safer substitute for lead-based driers.
