3216FR Epoxy Resin
DESCRIPTION:
The production is mainly applied in fire retardant level requirement of fiber reinforced composite material structures, such as rail transportation, yachts, car interiors and part structure composite material. This resin composite material structure, when heated and close to the fire will not release toxic and harmful gases. Especially suitable for infusion process, RTM process (low viscosity and low surface tension of resin can quickly be capillary action, fully infiltrate various reinforced material) and had lay-up process. 3216FR resin with 3216AH is for infusion process; 3216FR resin with 3216BH is for hand lay-up process.

Recommended curing process:
3216FR epoxy resin system can curing at high than 15℃，if need to get the best mechanical properties and thermal properties, must be conducted under the condition of temperature after curing. Recommended to curing at room temperature after exothermic peak, after the exothermic peak, temperature to 80℃，the curing after 10 hours. Concrete curing temperature, curing time and heating rate should be carried out according to the product structure adjustment, to ensure that products fully cured.
