High Chlorinated Polyethylene (HCPE) Resin for Adhesives, Paints, and Coatings - China Suppliers and Factory
Products Description
White light small particles. Since the molecular structure does not contain double bonds and the chlorine atoms are randomly distributed, it has good weather resistance, ozone resistance, heat aging resistance, flame resistance, chemical resistance and oil resistance. Used to replace chlorinated rubber in adhesive production.
HCPE can also be used as adhesives, paints, flame retardants, and high-grade ink modifiers, which can improve adhesion, corrosion resistance, flame retardancy, and abrasion resistance. Used as paint raw material, the main anti-corrosion effect is chloride ion.
HCPE-A has a high molecular weight and high viscosity, resulting in extremely strong adhesive properties. It dissolves stably in organic solvents such as toluene and xylene, forming colorless or pale yellow transparent solutions. Its key characteristics are its low molecular weight and relatively low viscosity, yet its high bonding strength. It can be used in adhesives produced for a variety of PVC pipes, fittings, sheets, and other materials.

Application Fields
Used instead of chlorinated rubber to make adhesives. It can also be used as a modifier for adhesives, high-grade inks and other products, which can improve adhesion, corrosion resistance, flame retardancy, and wear-resistant parts. Store in a cool, ventilated and dry warehouse, away from moisture.
A resin designed for high-performance adhesives, particularly excelling in bonding PVC materials. It can bond various pipes, fittings, and sheets made of polyvinyl chloride (PVC) or chlorinated polyethylene (CPE), as well as metals. It can also be used in the fiber industry. If your work requires strong bonding, HCPE-A is an excellent choice.
Mainly used for anti-corrosion coatings and fire-resistant coatings as a substitute resin for chlorosulfonated polyethylene.
Can be used as a special resin for steel anti-corrosion coatings and surface coatings for buried pipelines.
Due to its low viscosity, it can be compatible with acrylic resin and alkyd resin, and can be used as a special resin for anti-corrosion coatings, container coatings, road marking paints, and surface coatings for buried pipelines.
Due to the regular molecular structure, saturation, low polarity and good chemical stability of chlorinated rubber, various anti-corrosion coatings prepared with it have the characteristics of fast drying of coating film, good adhesion, resistance to chemical media and excellent resistance to moisture penetration.
Highly chlorinated polyethylene HCPE has excellent atmospheric aging resistance and chemical medium resistance, is easily soluble in aromatic hydrocarbons, esters, ketones and other organic solvents, and has good compatibility with most inorganic and organic pigments used in coatings. Generally, it is suitable for dissolving into 40% solid content resin solution for painting.
Frequently Asked Questions (FAQ)
What are the primary applications of Highly Chlorinated Polyethylene (HCPE)?
HCPE is mainly used to replace chlorinated rubber in adhesive production. It also functions as a modifier for adhesives, paints, flame retardants, and high-grade inks, enhancing properties like adhesion, corrosion resistance, flame retardancy, and wear resistance.
How do HCPE viscosity grades (L, M, H) differ in application?
HCPE-H (high viscosity) is ideal for anti-corrosion and fire-resistant coatings. HCPE-M (medium viscosity) is designed for steel anti-corrosion and buried pipeline coatings. HCPE-L (low viscosity) is compatible with acrylic and alkyd resins, making it suitable for container coatings, road markings, and anti-corrosion paints.
What precautions should be taken when using HCPE in summer paint production?
During summer grinding, if the temperature exceeds 60°C, cooling measures must be taken or the solution must be configured separately. This is because chloride ions precipitate at 56°C, which reduces the paint's anti-corrosion performance.
Which solvents are suitable for dissolving HCPE?
HCPE dissolves stably in organic solvents such as toluene, xylene, aromatic hydrocarbons, esters, and ketones. It forms colorless or pale yellow transparent solutions and is typically dissolved into a 40% solid content resin solution for painting.
What are the storage guidelines for HCPE?
HCPE should be stored in a cool, dry, and well-ventilated warehouse, kept strictly away from moisture to maintain its chemical stability and product quality.
