Paint knowledge | what is primer? What are the functions of primer

Core tips: some people think that the top coat can be used without primer if it is of good quality In fact, this is not true Because the function of the top coat is different from that of the primer, the top coat focuses more on the final decoration and apparent effect, while the primer focuses on improving adhesion, anti-corrosion function, alkali resistance, etc Next, I will introduce what is primer and what is the function of primer Primer refers to a kind of paint that can be directly applied to the surface of the object as a solid foundation of the top coat It is the first layer of the paint system, mainly used to improve the adhesion of the top coat, increase the fullness of the top coat, provide alkali resistance and anti-corrosion functions At the same time, primer can guarantee the top coat Uniform absorption 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 Home of coatings news: some people think that the top coat can be used without primer if its quality is good In fact, this is not true Because the function of the top coat and primer is different, the top coat is more focused on the final decoration and appearance effect, while the primer is focused on improving adhesion, anti-corrosion function, alkali resistance, etc Next, I will introduce what is primer and what is the function of primer Primer refers to a kind of paint that can be directly applied to the surface of an object as a solid foundation of the top coat It is paint The first layer of the system is mainly used to improve the adhesion of the finish, increase the fullness of the finish, provide anti alkali and anti-corrosion functions, while the primer can ensure the uniform absorption of the finish, so that the paint system can play the best effect According to the coating requirements, the primer can be divided into first primer, second primer, etc Some people say that primer can be dispensed with if the quality of finish is good, which is incorrect, because the function of finish is different from that of primer, which focuses on the final decoration effect, while primer focuses on improving adhesion, anticorrosion function, alkali resistance and other effects The role of primer, adhesion, primer in the emulsion content is relatively high, adhesion is also strong, good penetration, after using primer, can effectively improve the latex film and wall adhesion At the same time, the good adhesion of the primer can make the wall more smooth, and is more conducive to the painting of the top coat, reducing the use of the top coat The function of primer II If the wall surface in the home is not strong alkaline and relatively flat, the primer can not be used, of course, the effect of primer will be better Painting a layer of sealed primer before painting the top coat can not only save the decoration cost, but also have the advantage of half the effort in the long term Painting primer can make the wall smoother, avoid paint problems, and help to maintain the painting effect for a longer time Why not The function of primer 3 The alkali of sealing some walls is strong After soaking in moisture and water, alkali flowers will be produced, also known as pan alkali This situation will cause crater like protrusion on on the surface of paint film, and a layer of alkali frost will be formed in serious cases, which will eventually destroy the paint film However, if the primer is made, such a situation can be alleviated and the wall can be sealed If it is a dry wall with high floors, it may not be a problem without primer, but it is better to brush primer for the sake of safety Editor's summary: what is primer and what is the function of primer are introduced here 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,
