From the viewpoints of molecular structure, molecular polarity and molecular interaction force, the adhesion of the paint film results from the polar group orientation of the polymer molecules in the coating, and its polar group with the polar molecules on the surface of the coated object. The mutual attraction between each other.Only when the polar phase of the two is adapted to obtain a good adh...

Adhesion type and adhesion property of paint film on substrate The adhesion of the paint film to the substrate is divided into two types: mechanical adhesion and chemical attachment.Mechanical adhesion depends on the properties of the coated sheet (roughness, porosity) and the strength of the formed film; chemical adhesion refers to the mutual attraction of the paint film molecules and the plate m...

Some surface properties of plastic substrate affect coating, and the properties related to coating mainly include the following aspects: Due to the characteristics of the plastic substrate itself, its smooth and compact, low surface energy is not conducive to the wetting and adhesion of the coating on the substrate. The crystallinity of the plastic affects the adhesion of the film, and its crystal...

Plastics are classified into two types: thermosetting and thermoplastic.Among them, thermosetting plastics have high cross-linking density, good solvent resistance and heat resistance, relatively high surface polarity, and wide range of coatings available.For example, unsaturated polyester is called polyester fiberglass. The texture is hard and polar, and there are many coatings that can be used. ...

Due to the chemical composition of the wood and the particularity of the wood fiber, if it is not handled properly, the water-based paint film will be damaged. Wood is composed of cellulose and a small amount of gum, resin (rosin), pigment, tannin and the like. Although the amount of gum, resin, pigment, tannin, etc. is small, it has a large negative impact on the properties of the coating (mainly...

To master waterborne wood coatings and coatings, you must be familiar with the characteristics of wood. In this way, we can find the root cause of the problem in the painting process and make the necessary preventive and treatment measures. Wood is a natural fiber material, seen from the cross section of the trunk, it is a uniform material composed of layers of different materials, with many textu...
