Highly hydrophobic, oil-repellent, and stain-resistant nano-protective coating structure

Abstract

This invention provides a highly hydrophobic, oleophobic, and stain-resistant nano-protective coating structure suitable for the protection of various substrates such as glass, ceramics, and metals. The coating contains a solvent-free ethanol-free coating agent and a silicone oligomer curing impregnating agent, which are mixed in a weight ratio of 3:1 to 5:1. This invention uses silicone oligomer synthesis technology to introduce highly hydrophobic and highly oleophobic functional groups into the silicone oligomer backbone to form a three-dimensional structure that forms a stable chemical bond with the substrate surface. During the curing process, only ethanol molecules are released as a byproduct, making it environmentally friendly and non-corrosive. It maintains stable performance even after accelerated aging tests, achieving the goal of high hardness, long-lasting hydrophobicity, oleophobicity, stain resistance, and environmental friendliness.
