#foundry resin

SINYE No-bake Furan Resin is a kind of foundry resin produced in accordance with & superior to its industrial standard. It is our earliest and continuously improving key product, as well as one of the earliest users trust products.   Characteristics: Excellent fluidity of the mixture, easy for manual or mechanical sand filling, good roughness of casting surface and high dimensional accuracy. Excellent hardening properties, easy for demoulding, good thorough-hardening properties, sand core (mold) with excellent normal & high temperature properties.     Suitable for production of steel, iron, nonferrous castings, with excellent quality records.

SINYE Sulfonic Acid Catalyst is the matching hardener for SINYE No-bake Furan Resin. According to the different room temperature and sand temperature, users could choose different types of hardener to get satisfactory curing speed. By adjusting the addition rate of the hardener (30-60% of Resin), you can get different bench life and stripping time.

Characteristics:This binder system doesn’t contain harmful foundry elements: Nitrogen, Sulfur, Phosphorus, etc., which is especially suitable for the production of steel alloys, carbon steel and ductile iron casting. The binder system has second curing under high temperature and good thermo plasticity, which can reduce hot crack, veining, defect of steel and ductile iron casting, as well as improve the dimensional accuracy of the castings.

Characteristics:Free of Nitrogen, Sulfur, Phosphorus etc. harmful elements, which is especially suitable for the production of steel alloys, carbon steel and ductile iron castings, avoid foundry defects caused by N. S. P.Good thermosplasticity for the sand mold, keep off hot crack defect for steel alloys, carbon steel and ductile iron castings. This resin binder system is available with core shooter for automatic production, or manually making the mold and core, or facing sand, backing sand use cooperatively with water glass CO₂ sand.

Characteristics:Higher strength, better water resistance, easier stripping, less mold sticking, better fluidity for the mixture, longer bench life, faster curing speed, better toughness and collapsibility on high temperature, lower free formaldehyde, reduce benzene class gases by 70%. Less resin addition rate, lower technical requirement, less consumption of mold releasing agent and cleaning agent, lower shooting pressure, higher strength, less cleanups, higher utilization, lower rejection rate, better working circumstance, more environmental friendly.

Characteristics:Excellent fluidity of the mixture, easy for manual or mechanical sand filling, good roughness of casting surface and high dimensional accuracy.Rapid curing speed, no water generated during reaction, curing homogeneously with excellent thorough-hardening. High productivity, suitable for steel, iron, nonferrous castings, have excellent quality records on these castings.

Characteristics:Excellent fluidity of the mixture, easy for manual or mechanical sand filling, good roughness on the casting surface and high dimensional accuracy.Rapid curing speed and curing homogeneously with excellent thorough-hardening. Good collapsibility of sand core (mold) after pouring, easy for sand removal.
