Insulcast 125

Request Quote Request Sample

INSULCAST 125 is a low viscosity, general purpose potting and casting compound. The low viscosity enables it to be used in potting densely packed modules, thereby insuring good flow and penetration around components. INSULCAST 125 contains non-abrasive fillers and  suitable for automatic dispensing equipment.
