LR-302 Fastener Zinc-Aluminum Lubricating Composite Coating

Product Description

LR-302 Fastener Zinc-Aluminum Lubricating Composite Coating is a milky white, transparent water-based liquid. After application, it forms a dry and transparent lubricating film on the surface of the workpiece. This film exhibits excellent lubricity, reduces the friction coefficient and maintains stability. It has good adhesion to different materials. The product ingredients are safe, environmentally friendly, stable, and harmless to the human body.

Application Scope

LR-302 Fastener Zinc-Aluminum Lubricating Composite Coating provides pre-lubrication for zinc-aluminum chromate or chromium-free environmentally friendly coatings. When applied to DACROMET® or GEOMET® primer coatings, it provides a controlled friction coefficient for threaded components and increases corrosion resistance. It is particularly suitable for the batch lubrication treatment of small parts, such as products made of stainless steel, aluminum, or plastic. For screw types, it includes self-tapping screws, chipboard screws, sheet metal screws, beechwood screws, construction screws, locknuts, and screws and nuts after electroplating, such as wire mesh screws.
