Specifications

Feature: Furan resin is a general name of polymer which is used furfural as based raw materials. All macromolecule of furan resin contain furan ring. No-bake/self-hardening furan resin is an environmentally friendly product that reaches international advanced level. Furan resin is suitable for all kinds of iron casting, steel casting and non-ferrous casting. As usual, the furan resin appear pale yellow to brownish red liquid. To use furan resin as sand mold binder for casting, it always has below advantage:
    1) Lower viscosity of furan resin that is convenient to measure and easy to mix with sand. And the sand mold is also in good mobility.
    2) Lower free formaldehyde content with less smell that improve workers' working condition, and reduce pollution of environment.
    3) High strength of furan resin that can reduce the cost by using less resin while also can improve quality of casting.
    4) Good mobility of sand mold that reduce the workload of clean sand.
    5) The casting produced by furan resin is in precision size, shape edge, smooth and clean surface.
    6) It can control the curing speed of furan resin by adding the quantity of curing agent.

Furan resin use parameter:
Sand: furan resin: curing agent = 100 (0.8-1.5): (0.3-0.8) (weight ratio)
As usual, the furan resin should add 0.8%~1.5% of sand weight, and the curing agent always adds 30%~80% of furan resin weight.

Considerations:
    1. Firstly, use continuous system or sand mixer to mixing sand and curing agent. Then add furan resin to mix. The time of mixing sand always is 5s-60s. It should be used immediately after the sand mixing well.
    2. Use matching with the curing agent produced by our company for furan resin will be better.
    3. The furan resin is unfit to mix with acidic substances (such as curing agent) directly, preventing leakage and dangerous.
    4. The furan resin should be stored in a cool place, away from the fire source, preventing heat or sunlight.

Quality guarantee period of furan resin: 12 months
