Decorative function Rich color selection: A variety of colors are provided to meet the personalized needs of different customers for exterior colors. Whether it is bright colors for iconic buildings or soft tones for home decoration, ideal decorative effects can be achieved. Excellent gloss: Different gloss levels can be mixed. For example, high gloss can be used for products with strong display to increase brightness and texture; matte is used in places that pursue a low-key and soft appearance, such as museums, art galleries, etc., to reduce light reflection and create a comfortable visual environment. Protective function Weather protection: It can resist erosion by natural factors such as ultraviolet rays, rain, wind and sand, prevent coating aging, fading, and powdering, and extend the service life of the coated object in outdoor environments. If the topcoat is used on outdoor billboards, it can keep the color bright and the surface intact for a long time. Chemical protection: It has good tolerance to acids, alkalis, salts and various chemical substances. It can be used on the surface of equipment and pipelines in chemical, electroplating and other industries to prevent chemical corrosion and ensure the normal operation of the equipment. Waterproof and moisture-proof: Excellent water resistance can prevent moisture penetration and prevent the coated object from getting damp, rusting and rotting. For facilities that are often in contact with water, such as ships and bridges, the use of this topcoat can effectively protect the base material and extend its service life. Wear and scratch resistance: The paint film with high hardness and toughness can resist friction, collision, and scratching, and protect the surface of the coated object from damage. For example, it can be used in areas prone to wear such as floors and mechanical shells to reduce wear marks and maintain appearance and performance. Other functions Good construction performance: It can be applied by brushing, spraying, rolling and other construction methods. It is convenient to apply and dries quickly, which can improve construction efficiency and shorten the construction period. Adapt to different substrates: It has good adhesion to various substrates such as metal, wood, plastic, concrete, etc. It can be widely used on the surfaces of objects of different materials, expanding its scope of use. Insulation performance: It has certain insulation properties and can be used for surface coating of some equipment that requires electrical insulation, which plays an insulating protection role and improves the safety of the equipment.
Excellent decorative properties: A variety of colors are available, with bright and full colors and good gloss. Different gloss effects can be formulated according to needs, such as high gloss, semi-gloss, matte, etc., so that the surface of the coated object has a beautiful appearance. Good weather resistance: It has excellent UV resistance. During long-term outdoor use, it is not easy to powder, discolor and lose gloss. It can maintain the appearance and performance of the coating, and effectively resist the erosion of natural environmental factors such as wind, sun and rain. Excellent chemical resistance: It has good tolerance to chemical substances such as acids, alkalis and salts, and can resist corrosion from a variety of chemical media. It is suitable for some industrial environments with chemical corrosion risks, such as chemical workshops and electroplating plants. High wear resistance: The cured paint film has high hardness and toughness, good wear resistance, can resist mechanical effects such as friction and scratching, and is not prone to wear, scratches and other damage. It can be used on surfaces that are often rubbed, such as the ground and mechanical equipment housings. Good water resistance: It has excellent waterproof performance, can effectively prevent moisture from penetrating into the surface of the coated object, and prevent the base material from corrosion and rust due to moisture. It is suitable for humid environments or objects that are often in contact with water, such as ships, water facilities, etc. Strong adhesion: It has good adhesion to a variety of base materials, such as metal, wood, plastic, etc., and can be closely combined with the base material to form a firm coating to ensure that the coating is not easy to fall off during use. Low temperature curing: It can still be cured into a film at a lower temperature. Compared with some other types of coatings, it has relatively low requirements for the construction environment temperature, which can broaden the construction season and construction conditions to a certain extent and improve the flexibility of construction.
