Primcote binder is the investment casting industry’s leading colloidal silica based primary binder. Primcote binder was formulated to eliminate buckling, lifting and cracking of primary shell coats.

Primcote binder allows faster drying of primary coats with lower humidity and/or increased air circulation. Primcote binder shell coats can not be over dried as standard colloidal silica shell coats can.

Primcote binder contains wetting agent, antifoam agent, a color indicator to monitor shell dryness as well as other proprietary ingredients. This binder is also compatible with conventional refractory materials and shell room equipment.

Whether casting simple or complicated parts, Primcote binder is the industry’s primary binder choice.
