What is the main function of automobile primer and plastic primer?
The main role is to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkaline resistance, provide anti-corrosion function, etc., while ensuring uniform absorption of the finish paint, so that the paint system to achieve the best results
Primer refers to a coating that is applied directly to the surface of the material as a solid base for the topcoat. It is required to adhere firmly on the surface so as to increase the adhesion of the upper coating and improve the decorative property of the topcoat. According to the requirements of coating can be divided into two primer primer, etc..
Primer is the first layer of paint system, used to improve the paint adhesion, increase topcoat fullness, alkali resistance, corrosion protection function, and can ensure the uniform absorption of paint, paint system to play the best results. Finish quality is good without primer, this is wrong, because the finish and primer finish function is different, more focused on the final decoration and apparent effect, and the primer focuses on improving the adhesion, corrosion, anti alkaline.
Before brushing the topcoat, brushing a layer of sealing primer, not only can save the cost of decoration, from the long-term and decorative effect point of view, brushing paint more work half time advantages. At the same time, primer good adhesion to make the wall more smooth, make the paint more easily brushing, reduce the use of topcoat. As a result, the wall avoids the paint disease and helps to maintain the brushing effect for a long time.
The function of primer:1.: some closed wall is stronger, the moisture and water immersion after alkali flower, scientific name "frost", this situation caused by the formation of a volcano like projection film surface, a layer of frost formation of severe alkali in the film surface, the film is broken. Latex paint primer can be closed to alleviate this situation. However, if your house wall is relatively dry, and the floor is higher, it may not be a problem, but it is recommended that you use insurance.2. adhesion: high emulsion content and strong adhesion in the primer. It can improve the adhesion between latex film and wall.3. fill up: if your wall is not strong alkaline and more smooth, you can not use primer, of course, the use of better.
