Boron Nitride High Temperature Coatings

High Temperature Coatings and Release Agents for Aluminum, Magnesium, Zinc and Lead Foundries

Our AMZL Release Agents use Hexagonal Boron Nitride powder as a key ingredient for utmost efficiency and can be formulated with Water, Oil or Ethanol. Due to the unique lubricating properties and inertness to molten metals and salts the Boron Nitride powder is ideally suited as a mold and die release agent for high temperature paints and coatings. We optimized our AMZL line of Release Agents to perform most efficiently in the tough conditions of Aluminum, Magnesium, Zinc and Lead foundry applications.
