SWANCOR 997

Chlorendic Polyester Resin

Product Description

SWANCOR 997 is a low viscosity unpromoted chlorendic polyester resin, designed for highly corrosive resistance applications. SWANCOR 997 is particularly suitable for use in demanding and aggressive chemical environment containing chlorine, which presents highly oxidizing tendency. It also retains excellent mechnical strength at high temperature. With excellent heat resistance, it can be used for fume and gas environment up to 175oC, meanwhile it provides excellent flame retardancy.  

Applications

•  Chemical environment against high temperature wet chlorine gas, hydrochloric acid, salt solutions, concentrated sulfuric acid (wt% over 70%), phosphoric acid, chlorinated wax, isopropylene and sulfur dioxide etc. FRP parts include chemical storage tanks, pipes, fume gas desulfurizing systems (FGD), scrubbers and ducts etc.  

•  Corrosion resistance flooring while incorporated with aggregates.

Fabrication Methods

•  Can be easily applied by hand lay-up laminating, spray-up, pultrusion, RTM, and filament winding.

•  Can be used in polymer concrete casting.

Storage and Handling Precaution

Customers are requested to review MSDS (Material Safety Data Sheet) for precaution and noticebefore handling the product.

Storage

SWANCOR 997 should be stored in the dark and under roof at temperature not exceeding 25oC. Keep away from direct sunshine, sparks and flame. The resin should be used within 6 months from the date of production.

Handling Precaution

Avoid contact with skin and eyes. Do not breathe the vapors. Wear protective equipment such as gloves and goggles before handling. If contact with eyes or skin, wash the areas with soap and large amount clean water. Remove the contaminated clothing immediately. Wash contaminated clothing before re-use.

Waste Disposal

Incinerate the waste in accordance with local regulation. Do not dispose the resin into river and lake due to harzardous properties.

Packing

Standard packing is 200Kg steel drum.
