Product Overview
BONDERITE® L-CA 632 (also known as DAG 632) is an insulating coating of refractory pigments in a water base. BONDERITE® L-CA 632 can be used in various casting applications including permanent mold, low pressure casting, and as a gate and riser coating. BONDERITE® L-CA 632 has excellent adherence to the mold and good abrasion resistance. BONDERITE® L-FG 137 or BONDERITE® L-GP PRODAG is often applied as an overcoat for part release.

Problems Solved
BONDERITE® L-CA 632 helps provide a solution to the following industry & application problems: 

Poor die life
Excessive down-time and scrap pieces due to poor quality castings

Diluted BONDERITE® L-CA 632 should be spray applied, multiple coats are typically required to achieve the recommended coating thickness of 1-3 mils. The typical dilution ratio is 1:1 (BONDERITE® L-CA 632:water); the concentrate should be agitated before and during dilution. Molds should be clean and preheated to 149°-204°C (300°-400°F) prior to application. The coating should be air dried for 20 min prior to casting.
