Bitumen Primer
Bitumen Primer is a high-performance, solvent-based or water-based coating designed to prepare and seal surfaces before the application of bituminous waterproofing or roofing systems. It enhances adhesion by binding dust, reducing surface porosity, and creating a tacky base layer for membranes, felts, and asphalt-based applications. Bitumen Primer is quick-drying, highly penetrative, and applicable to a wide variety of substrates including concrete, masonry, metal, and wood. It plays a critical role in extending the durability and effectiveness of waterproofing systems in construction and industrial environments.
Bitumen Primer

Chlorinated Paraffin
Chlorinated paraffins are complex mixtures of polychlorinated n-alkanes produced by reacting chlorine gas with unbranched paraffin fractions derived from petroleum distillation. They appear as colorless or yellowish viscous liquids or solids depending on chain length and chlorine content. Chlorinated paraffins are classified based on carbon chain length into short-chain, medium-chain, and long-chain varieties. Technical grade chlorinated paraffins are manufactured for industrial applications including plasticizers, flame retardants, metalworking additives, and surface coatings. They exhibit excellent compatibility with polymers, high thermal stability, water resistance, and chemical resistance.
