What is PU paint? What is the difference between PU paint and UV paint

Core tip: you may have heard about PU paint when you buy paint What is PU paint, environmental protection, advantages and disadvantages? What is the difference between PU paint and UV paint? Let's learn about it together What is PU paint? PU paint is the general designation of all polyurethane coatings Its film-forming mode is natural film-forming without special process PU paint is the most high-grade paint in the current decorative wood work It is generally used in high-grade furniture because of its high cost At present, it is rarely used in wooden door enterprises At present, the Pu topcoat we use is NCO / Oh two-component polyurethane coating, which is the most widely used and most promising in polyurethane coating system Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: when buying paint materials, you may have heard about PU paint What is PU paint, environmental protection, advantages and disadvantages? What is the difference between PU paint and UV paint? Let's learn about it together What is PU paint? PU paint is the general designation of all polyurethane coatings Its film-forming mode is natural film-forming without special process PU paint is the most high-grade paint in the current decorative wood work It is generally used in high-grade furniture because of its high cost At present, it is rarely used in wooden door enterprises At present, the Pu topcoat we use is NCO / Oh two-component polyurethane coating, which is the most widely used and the most promising one in the polyurethane coating system The so-called NCO / Oh two-component polyurethane coating is based on the prepolymer of polyisocyanate (i.e curing agent, the trimer of hexamethylene diisocyanate (HDI) used by our company, which belongs to the non yellowing aliphatic diisocyanate, and the PU paint made of it has good weather resistance and light stability) as component A or component A, and the high molecular compound containing hydroxyl (the hydroxypolyacrylic acid tree used by our company is hydroxypolyacrylic acid tree Fat) is component B or component B Advantages and disadvantages of PU paint advantages and disadvantages of PU paint: compared with other kinds of paint, PU paint film has the highest elongation at break due to the effect of hydrogen bond under the same hardness, so it is widely used in floor paint and deck paint; it has both protection and decoration, and can be used in the coating of high-grade crafts, high-grade woodwork, piano, large airliner, etc.; the film has strong adhesion The paint film has excellent adhesion to a variety of surfaces (metal, wood, rubber, concrete, some plastics, etc.) The paint film has excellent chemical resistance, acid, alkali, salt and petroleum products, so it can drill into the maintenance coating of platform, ship and chemical plant, inner wall lining of petroleum storage tank, etc It can be dried and solidified at low temperature The construction season is long Disadvantages of PU paint: not very environmentally friendly, developed countries in Europe have basically eliminated The export of PU paint products is limited The difference between PU paint and UV paint 1 Essence: there is not much difference between them in terms of names, but the essence of PU paint and UV paint is different PU paint is polyurethane paint, while UV paint is generally epoxy resin 2 Film: PU paint film is thin and not very hard, while UV paint film hardness is high, adhesion is not as good as PU paint 3 Usage: PU paint and UV paint have the same point that they are also widely used in modern home decoration, and have good glossiness 4 Price: from the current market of building materials in China, we can know that the current UV paint is relatively reasonable, while the price of PU paint is generally higher than that of the same UV paint 5 Flexibility: the flexibility of UV paint is not as good as that of PU paint In case of accidental collision, it is easy to block and fall off Of course, it is also related to production technology, such as whether the spraying is uniform, factory environment, etc The above is the introduction of PU paint related knowledge I hope it can help you, and I want to know more about paint and continue to pay attention to decoration Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
