Product Description

Houghto-Phos 6300 is a manganese phosphate product designed to be used for break-in lubrication of iron and steel materials. Houghto-Phos 6300 is designed to produce excellent manganese phosphate coatings at lower temperatures with finer and more consistent crystal morphology than similar high temperature products. Houghto-Phos 6300 is applied by immersion with a normal process coating weight range of 500-1000 mg/ft2.

Houghto-Phos 6300 is a single package product that is used for both makeup and replenishment. The bath will be controlled via total acid, free acid, and iron points. Titrations should be done multiple times per day. Before taking samples for titration the tank should be filled to the normal operating level and thoroughly mixed.
