Processing Performance:During the curing reaction do not produce low molecular volatiles, has good compatibility with all kinds of packing, high bonding strength, good flexibility, after curing of diamond grinding wheel with phenolic resin sand round compared to its mechanical strength with 30 ~ 40%, heat-resisting temperature more than 50 degrees higher, too.

when grinding wheel itself ,the temperature is low, grinding sound is ringing, the surface of the machined part has higher quality and lower surface roughness.

molding equipment and process is same as the phenolic resin. curing speed is faster.

usage: this product appearance for yellow superfine powder, mainly used as diamond wheel, high-speed heavy-duty resin grinding wheel and grinding resin grinding wheel bond strength, it has excellent heat resistance, abrasion resistance, molten liquidity is good, the abrasive has good wetting and bonding performance.

Processing is convenient, good in usability, long-term use of the results showed that this product has been the preferred ideal binder, users.

PI products as high temperature resistant polymer and resin of high performance composite matrix resin, are also increasingly widely used in aerospace, electrical/electronics, motorcycle, automobile, precision machinery and automatic office machinery, and other fields can be used in the preparation of high resistance, low temperature solid self-lubricating materials, precision machinery parts, all kinds of bearings, gaskets, sealing ring, radar equipment, molded products, paint, adhesives and electric insulation board, insulation tube, transformer insulation of wire coil, coil high-performance electrical insulation materials and other products.
