|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.|
|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
|Moisture Tolerant Parts —||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.
