Vinyl resin hc3201

HC3201 HC3201 resin, vinyl ester resin, which is typical of epoxy vinyl ester resin, the resin has excellent mechanical properties and good heat resistance and corrosion resistance. Suitable for hand burnt molding, continuous winding, pultrusion molding process. Products can be widely used in situations requiring high corrosion resistance, such as the manufacture of various high-grade glass fiber reinforced plastic (FRP); corrosion slot, cans; heat pipes and equipment; anti-corrosion chemical, electroplating, electrolysis and other industries flooring; various FRP high-strength structural parts, corrosion-resistant fiberglass grille. Liquid resin technical indicators Item Index Appearance light yellow to brown yellow transparent liquid Viscosity Pa?

Reference Formulators name Ⅱ # HC3201 resin curing system 100 Ⅱ # hardener 2-62 # accelerator 1-3 Note: The above formula is for reference, according to the construction method, different construction speed, ambient temperature and humidity prior to use to regulate the level of the curing system. Ingredients should be first added to the resin curing agent (or accelerator), stir then add accelerator (or curing agent), you can fully mix after construction, the construction of the ambient temperature is not lower than 15 ℃, (preferably is 20 ± 2 ℃), humidity no higher than 80%. After curing at room temperature (20 ℃) ??curing 24 hours, then at 30 ℃, 40 ℃, 80 ℃ for 3 hours each, or continue a month at room temperature curing, square up to the highest intensity. Prior to this put into use, such as from cold, rain and other bad weather affect the intensity can be gradually reached the highest value. Storage and shelf life of 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. Prevent dripping injection. 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, for that have been opened and partially used 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. The law does not guarantee certain properties for a specific use.
