Microcrystalline wax used for rustproofing

The rust-preventive mechanism and advantages of microcrystalline wax lie in
its high molecular weight structure and adhesive properties.‌ Its chemical
composition, featuring long-chain naphthenic hydrocarbons, enables thorough
wetting of metal surfaces upon melting. Upon cooling and solidification, it
forms a continuous, resilient film that effectively blocks environmental
moisture and electrolytes; Furthermore, microcrystalline wax exhibits
superior gel strength and adhesion compared to ordinary paraffin wax,
enhancing the coating's resistance to wear and peeling. This makes it
particularly suitable for protecting metal components in dynamic or vibrating
environments.
‌Specific applications include rust prevention for metal products, thickening
industrial greases, and rubber protection.‌ For example:
Direct application as a short-term rust-preventive coating or impregnation
treatment for metal products;
As a thickening agent in greases to enhance sealing properties and weather
resistance;
Preventing surface chalking and cracking in rubber goods, thereby indirectly
aiding rust prevention.‌
