Marine resin 306s

306S, 196S, 191S general purpose resin 306S, 196S, 191S are phthalic series of general-unsaturated polyester resins. It is currently GRP (FRP) product manufacturing, the use of the largest, most widely used varieties. 191S and 306S which has won the Ministry of Chemical Industry quality products title. Three resins have good curing activity and moderate viscosity. Wherein 191S rigid resin, suitable for the production of the transparent sheet and other products; 306S excellent corrosion resistance, it can be used in shipbuilding; 196S of firmness and flexibility resins can be used in the production of winding pipes and other products, in general, three resins can be mutually substituted.

Recipe name Ⅰ Ⅱ curing systems curing system resin curing system Ⅴ 100,100,100 hardener 2-6 2-6 1-3 accelerator 1 to 31 ~ 31 ~ 3 above formula is for reference, changes in temperature during the construction, methods of operation and construction at different speeds, inputs curing System should be adjusted. First added to the preparation of a curing agent (or accelerator), stir then add accelerator (or curing agent), can be used after the full mix. The environmental temperature should not be below 15 ℃, relative humidity not higher than 80%. Storage and shelf life of the resin and curing system both are flammable, covered with tarpaulin to transport the hot season. When storing away from fire, heat, should be placed in the shade. Curing agents and accelerators to be segregated. Shelf resin is: below 20 ℃ stored for six months at below 30 ℃ for three months. Shelf life from date of manufacture computing, and that have been opened for the use of a part of the product warranty does not cover. ★ This information is based on national standards (GB) determination, because there are many factors in the process, so do not rule out the need for user-testing research.
