Boron nitride protective coating for iron and steel molds.
BONDERITE® L-CA 634 (also known as DAG 634) is a finished boron nitride coating that lubricates and protects iron and steel molds in die casting applications. BONDERITE® L-CA 634 provides excellent release, protects molds from heat degradation, and helps with part removal where there are low draft angles. The coating is white and there is minimal coating transfer to the ingot.

BONDERITE® L-CA 634 helps provide a solution to the following industry & application problems:
Poor mold life
Die soldering from molten metal
Diluted BONDERITE® L-CA 634 should be spray applied, several coats may be required to achieve the desired thickness of 1-3 mils. Typical dilution ratio is 1:3 (BONDERITE® L-CA 634:water), the concentrate should be agitated prior to 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 before use.
