German Pergut S5 S10 S20 S40 Chlorinated Rubber resin Cr5 Cr10 Cr20 Cr40 for Paint and Coating
Product name:
Chemical formula of chlorinated rubber (CR) : [ C10h11cl7]
Product introduction
Chlorinated rubber is a kind of chlorinated polymer made from natural rubber and chlorine gas. Industrial products are white or light yellow powder, non-toxic and tasteless, chlorine content of 63-65% , average molecular weight of 5000-10000, soluble in aromatic hydrocarbons, halogenated hydrocarbons, ethers, esters, petroleum solvents and ketones (excluding acetone) , can be mixed with alkyd resins, epoxy, Phenol formaldehyde resin, polyurethane and other synthetic resins, insoluble in aliphatic alcohols and water. Due to the high chlorine content in the C-C backbone of chlorinated rubber and its ring-like structure, it has many excellent application properties:
1. The molecular chain is saturated and does not contain double bond and other active groups, so it has stable chemical properties and excellent corrosion resistance. It can withstand the corrosion of acid, alkali, salt, chlorine, H2S, SO2 and other corrosive chemicals
2. Cl-group has anti-mildew and flame-retardant properties, so the product has anti-mildew and flame-retardant properties;/n3. C-Cl bond has strong polarity, so it has good adhesion on many kinds of materials such as steel, aluminum alloy, cement and wood/n4. It has C-C main chain and belongs to rubber modified product, so it has good compatibility with natural rubber, neoprene rubber, nitrile rubber rubber, etc. /n5. It has a ring structure, so the adhesive property, flame retardancy, oil resistance and elastic modulus of the product can be improved/n6. Micro-decomposition above 125 °C, no softening and burning above 200 °C, good heat resistance.

Performance:
It has excellent weather resistance, chemical stability, salt and acid resistance and uv resistance performance, and has excellent adhesion on steel, cement and other substrates. CR-5 is a new low-viscosity model developed by the company, which can help customers improve solid content in coating formulation and achieve VOC emission standards lower than 420g/L.
Solubility:
It can be stably dissolved in toluene, xylene and other organic solvents, forming a colorless or light yellow transparent solution. It is insoluble in ethanol-aliphatic solvents.
Stability:
It is very stable at ambient temperature, but it will degrade slowly in continuous heating. It is recommended to add low molecular weight epoxy resin as stabilizer in the production process, and the addition amount is less than 1%.
