Wesil RP

Binder system to replace phenolics

Wesil RP is a complete refractory fiber floccing and bonding system designed to replace the phenolic resin systems in riser sleeves and other foundry applications. Wesil RP contains cationic starch to floc the aluminosilicate binder on to the fibers and a non-toxic heat-set resin that sets up during drying to give extra hardness, strength, and resistance to moisture.

Wesil RP offers these advantages

Replaces Noxious Phenolics

Non-toxic heat-set resin replaces hazardous phenolic resin systems.

Increased Hardness

Heat-set resin can be used to replace starch and colloidal silica where extra hardness is required.

More Moisture Tolerant Finished Part

Formed parts are more able to maintain hardness and strength if exposed to humidity.

No Cristobalite

Completely cristobalite free at use temperature eliminating a common source of thermal shrinkage problems and health related concerns.
