1、 Features and main uses:
Tianrun TR-638 is an unsaturated polyester resin (modified) mainly composed of phthalic anhydride and standard diols. It has been dissolved in styrene and added with highly active flame retardants. It has low viscosity and high reactivity, excellent flame retardancy, light resistance, water resistance, and weather resistance. After curing, it has high mechanical properties and hardness. Especially suitable for FRP products with high requirements for flame retardancy, transparency, light resistance, water resistance, and weather resistance.
2、 Technical specifications of liquid resin (25 ℃):
|Transparent water white liquid|
Note: In a 25 ℃ water bath, add 2 ml of methyl ethyl ketone peroxide solution and 4 ml of cobalt isooctanoate solution to 100g of resin
3、 Physical properties of the casting body (for reference only):
Tensile modulus of elasticity
Elongation at break
Heat distortion temperature
Note: (1) The casting method shall be executed according to GB/T8237-2005; Temperature 25 ℃, curing system: accelerator RCA 1.0%, curing agent M-50 1.5%.
(2) Post casting curing treatment: room temperature × 24 hours+60 ℃ × 3 hours+80 ℃ × 2 hours;
1. Before use, please stir evenly in the packaging bucket, or pour out all the resin in the packaging bucket and stir evenly before use.
