Unsaturated polyester resin 182 Flexibility

182 182 pliable resin is flexible performance unsaturated polyester resin. 182 resin is generally flexible, has a low cure shrinkage and exothermic peak. Flexible resin is generally not used alone. It is mainly used to improve the performance of other unsaturated polyester resins. After some rigid or semi-rigid resin resin tuning added flexibility, the production of glass fiber reinforced plastic (FRP) products and cast products (such as artificial marble, jade, agate, etc.) can overcome the deflection, cracking or deformation. Technical indicators Project 182 Appearance light yellow transparent liquid Acid value (mgKOH / g) 15.5 ~ 23.5 Viscosity (Pa.S / 25 ℃) 0.14 ~ 0.23 gel time (min / 25 ℃) 10.5 ~ 19.5 Solid content (%) 62.5 - 68.5 mechanical properties Item 182 flexural strength (MPa) Casting 30 Elongation (%) Casting 24.0 Tensile strength (MPa) FRP 273 Flexural strength (MPa) FRP 226 flexural modulus (MPa) FRP 1.1 × 104 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. Recipe pliable resin and other resin ratio, generally controlled between 10% to 20%. Resin curing formulations and methods of use after mixing with other unsaturated polyester resin same. Storage and shelf life of the resin and curing system both are flammable, covered with tarpaulin to transport the hot season. To keep away from fire source, should be placed in the shade during storage. 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.
