What is
is applied of curing of Furan resin by acids as catalyst.We can control curing time by strength of acidity.
And
contains natural poly-phenol.Natural poly-phenol brings better working circumstance
due to lower odor, better property of curing and strength of mold.
We provide all necessity explanation of features of our phenolic resins and curing agents fully, in order to be used our products and system safety and exactly.
And we will support you totally, including temperature auto-control equipment to control curing speed.
Feature
- Workable with various types of sand like Silica sand, Special sand, ceramic sand, etc.
- Better working circumstance and casting quality in foundries.
- Reduction of formaldehyde gas in unbaked furan mold contained of poly-phenol.
- Higher compressive strength of unbaked furan mold.
- Lower viscosity then easy handling.
Evolution of NFURAN
Excellent strength
Effects of conventional and NFURAN on compressive strength of unbaked furan molds
Excellent mold strength at high LOI reclaimed ceramic sand
Breaking stress of mark
Low number of emission brings environment friendly
