Boron Nitride Paint-Aluminum Die Casting Release Agent

Overview – Mold Release Agent For Aluminum Die Casting

Definition and role
1. Definition: A release agent is an interfacial coating used on the surface of two objects easily adhering to each other.
2. Function: Form an inert BN coating between the mold and the module so that the module can be easily removed from the mold. This will improve the anti-wear performance and scratch resistance of the final product, making the surface of the object easy to detach, Smooth, and clean.

Principle
Since the lubricant substance (Boron Nitride Coating)is an easily pro-metal surface (mold surface), a static lubricant film layer is formed by adsorption, thereby reducing the friction between the polymer (module) and the processing equipment (mold). , produces a significant release effect and improves the surface finish of plastic parts.

Classification
1. Classification employing addition/use: internal release agent and external release agent.
The former is added directly to the molded plastic, while the latter is applied to the mold’s cavity surface.
2. Classification by chemical composition: inorganic substances, organic substances, and high polymers.
Inorganic release agent
Organic release agent
Polymer release agent
