ACRYLIC EMULSION
Paint chemicals 2025-03-21
Acrylic emulsion is a milky white polymeric emulsion, mainly produced with acrylic monomer undergoing polymerization, using an initiator in presence of emulsifier with water as a solvent. Acrylic emulsion possesses excellent adhesive and waterproofing properties, which can be used in the textile industry, such as for non-woven fabrics, flannelette blankets and lamination. Selected products can be used in civil engineering such as cement mortar, caulking and elastic cement, while other products can be used for coating material, such as indoor and outdoor water-based paint.
