How Many Years Can Headlight Restoration Coating Last?
1 Answers
Headlight restoration coating can last approximately two to three years. It is recommended that if the headlight cover cannot be restored through repair, the owner should replace it with a new one as soon as possible. Otherwise, the damaged headlight cover may affect the light output, posing serious safety risks. Types of headlight restoration coatings: 1. Fluorocarbon coatings and PTFE (Teflon) coatings, although slightly different in properties and functions, are both classified as fluorocarbon products in a strict sense. The characteristics of fluorocarbon products include excellent film-forming ability, corrosion resistance, weather resistance, and wear resistance. However, their biggest drawback is poor adhesion, as almost no substances can bond with Teflon coatings. 2. Resin-based coating products are characterized by good film-forming ability, strong adhesion, and low cost, making them widely used. However, they have poor hardness and gloss, as well as inferior oxidation resistance, corrosion resistance, and weather resistance, and are therefore being phased out gradually. 3. Silicone-based coating products, also referred to as glass fiber or glass element coatings, are the latest coating products on the market. The main component of these products is polysiloxane, which forms SiO2 (commonly known as glass) after film formation, hence they are also called glass-like coatings.
