Primcote Binder 56 Gallon Drum (241509)
Primcote binder is the investment casting industry's leading colloidal silica based primary binder. It has been 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 overdried as standard colloidal silica shell coats can. It contains a 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 of choice.

Primcoat Binder is mixed with either Ranco-Sil #2 or Ranco-Sil #4 and used in conjunction with Ranco-Sil "A" or Ranco-Sil"B" to build ceramic shells for Lost Wax Casting.
