Benefits of technology

This patented material works well for various applications where it needs strong waterproof properties such as metals or wood surfaces like doors and windows. Its coatings are resistant to rainwater damage while also having excellent color depths with great durability against wear from everyday usage over an extended period without any maintenance costs associated therewith. Additionally, this method uses less expensive equipment compared to traditional methods but still produces better results at higher speeds than previous techniques.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the properties of fluorescence carbon coatings that are currently available but have drawbacks like requiring expensive materials with long drying times, being difficult to apply due to their thickness, causing damage when applying them onto surfaces during application, having negative impact upon indoor air quality issues caused by volatile organic compounds released from paints made therefrom.

Abstract

The invention pertains to the coating field, in particular to a uv-curing fluorocarbon coating used for protecting and decorating building materials requiring high weatherability and a preparation method thereof. The main contents of the uv-curing fluorocarbon coating comprise fluorine-containing (methyl) acrylic acid modified prepolymer, reactive (fluorine-containing) acrylate monomer, photoinitiator, pigment, filler, addition agent, etc. Coating compositions of different mixture ratios are applied to building materials requiring high weatherability such as coil sheet, aluminum profile, aluminium plastic plates, plastic-steel profile, etc., and are characterized by thick paint film, rich colors, high hardness, good scratching resistance, weatherability, stain resistance, etc. Meanwhile, due to adopting uv-curing coating technology, the invention has the advantages of small production field, low equipment cost, high production efficiency, low energy consumption, and no pollution.
