Discuss the difference between PU and UV paints

Question one: What is PU paint, UV paint?

PU paint is a general term for all polyester coatings. Its film formation method is natural film formation without special processes. Its characteristics are: thin film is not very hard; but its adhesion is particularly good even teak wood with high oil content can be, not to mention; its gloss are called, looks not very bright, can be very good Show floor textiles and color; prices are relatively higher than UV paint.

UV lacquer is UV-cured lacquer. UV is ultraviolet code, and its raw material is generally annulation resin. Its characteristics are: high hardness of paint film, less adhesion than PU paint, paint film thickness can reach 0.6cm PU paint is 0.4cm. High gloss is divided into lacquer and roller paint, which can be divided into matt, semi-matt and light.

Problem two: UV paint has many advantages, and the cost is low, but it is used on the bamboo flooring with oily point. How do you know the firmness of the paint film? PU paint will not be better?

At present, Uv paint or Pu paint is mostly used in the production of bamboo flooring. The so-called Uv lacquer refers to the lacquer process using a photocuring lacquer, and Pu lacquer uses a urethane lacquer. The main difference between Uv paint and Pu paint is the difference in the process of its processing, and some light-curing paints also have polyurethane paint. Uv lacquer uses a light-curing process that is non-polluting when painting and is more environmentally friendly than Pu lacquer. From the factory's processing of flooring, it is good for workers' health and environmental protection. From a production perspective, it is a Kind of updated product. However, for the buyer, the floor finished product is already in the process of processing, so that the solvents in the paint surface volatilize, whether it is the Uv paint floor produced by the light curing process or the Pu paint floor produced by the traditional process. It does not pose a pollution hazard to users.

Question 3: The difference between UV paint and PU paint.

UV paint is UV-dried and suitable for floors with low grease. UV paint has strong luminosity, smooth surface, high hardness, no special odor, and high processing speed. However, UV lacquer is exposed to ultraviolet rays and instantaneously dried. It cannot penetrate into the wood and is easily peeled off. In particular, when the wood expands naturally and shrinks slightly, surface paint cracking occurs.

The PU paint adopts natural drying and penetration. Usually the oil takes 12 hours to penetrate again. The processing speed is slow. The PU paint has very strong permeability and flexibility. It penetrates into the surface of the wood, and it gives rise to the rise and contraction of the floor. Control the role of making it difficult to crack and paint off. The PU topcoat has stronger resistance to abrasion and abrasion than the UV paint. Suitable for floors with high grease, such as teak. Such wood cannot use uv paint.

Fluorocarbon paint is a new paint made from fluorocarbon resin plus pigments, additives, solvents, etc. It is superior to common paint types in terms of weatherability, salt spray resistance, scrub resistance, solvent resistance, non-adhesion, low friction, etc. Mainly used for architectural appearance and industrial purposes.
