JHD series self-hardening furan resin is an environmentally friendly casting adhesive used to make sand molds (cores). Different types of furan resin can be used to cast various metals, such as cast steel, cast iron, cast non-ferrous metals, etc. Its appearance is light yellow to reddish brown transparent liquid.

Advantages of the product

1. Low viscosity: the viscosity of the resin is low, easy to mix sand, and the flow of sand is good.

2. High strength and saving production costs: High resin strength can reduce the amount of resin added by 10%-20% and reduce production costs.

3. Fast curing speed: The fast curing speed of resin can shorten the production cycle and improve production efficiency.

4. Green environmental protection: The amount of gas released in sand molding is low, and the free formaldehyde can be controlled below 0.05%, which is lower than the free formaldehyde of ordinary resin. The amount of resin added is lower than that of ordinary resin, so the pollution to the environment and workers' workplaces is greatly reduced.

5. Stable quality and performance: The resin is synthesized by a new process, and the whole production process is automatically controlled by computer, which avoids the influence of human factors and ensures the stability of the resin quality.

6. It can improve the quality and finished product rate of castings: the reduction of the amount of resin added will reduce the amount of mold core gas, which is conducive to reducing or eliminating the pores defects of the casting; due to the fast curing speed, the amount of curing agent added is correspondingly reduced, which can reduce the defects of sulfuration and poor spheroidization on the surface of the casting.

7. High recovery rate of old sand: the recovery rate of old sand is as high as 97%.

8. Good dispersion: better disintegration than other ordinary resins.

9. Good high-temperature performance: good high-temperature performance, few casting defects, and accurate casting size.

10. There is no need to add silane when making the core: there is no need to add silane under any conditions, which can meet the production needs and simplify the operation of workers.
