Wings brand molding resin hc198

HC198 resin The product is phthalic unsaturated polyester resins for SMC / BMC molding process requirements. It has a high reactivity, rapid thickening, stabilizing thickening and other characteristics. Product shrinkage after forming a small, smooth surface, high heat resistance and impact strength. It can be used in the manufacture of automotive body panels, bumpers, bathtub high quality SMC / BMC products. Technical indicators Project HC198 Appearance clear liquid Acid Value (mgKOH / g) 21.0 ~ 29.0 Viscosity (Pa.S / 25 ℃) 1.0 ~ 1.8 gel time (min / 25 ℃) 9.8 ~ 18.2 Solid content (%) 61.0 - 67.0 Physical Mechanical properties program HC198 flexural strength (MPa) Casting 122 flexural modulus (MPa) Casting 3300 Impact Strength (KJ / m2) Casting 10.5 Elongation (%) Casting 3.0 heat distortion temperature (℃) Casting 95 bar Ke Hardness Casting 45 Tensile strength (MPa) Casting 71 Tensile Modulus (MPa) Casting 3400 Note: 1) sample preparation method according to GB / T8237-2005. 2) after heat treatment: after 24 hours at room temperature curing + 40 ℃ 2 小时 + 60 ℃ 2 小时 + 80 ℃ 3 3h + room temperature for 24 hours. Generally use high-temperature curing. Users can adjust the level of the curing agent according to the construction method, construction speed, the ratio of different raw materials. Storage and shelf life of 1, this product is metal pail, specification 210 kg / barrel. 2, should be stored in ventilated, dark, dry, cool place, separated from fire. 3, avoid strong collision and packaging damaged during transport, to transport the summer covered with tarpaulin. 4, the shelf life of six months or less 20 ℃, 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
