Can water based paints paint paint on metal and plastic surfaces? Can it be used outdoors?

Water-based coatings can be applied directly on wet surfaces and in wet environments; It has good adaptability to the surface of the material and strong adhesion of the coating.

Water-based coatings are highly corrosive to coating equipment, so anti-corrosion lining or stainless steel materials need to be used, and the equipment cost is high. The corrosion of water-based coatings on the transportation pipeline, the dissolution of metals, the precipitation of dispersed particles, and the pitting of the coating film, also need to use stainless steel pipes.

Metals will corrode.

Please give it to you.

Summary. Water-based paint can be brushed with plastic. The pigment particles of water-based paint are very small, which can penetrate the tiny holes on the surface of the plastic very well, so as to achieve good adhesion.

However, it should be noted that before brushing, the plastic surface needs to be fully cleaned and sanded to increase the adhesion and adhesion between the water-based paint and the plastic surface, and avoid the paint surface falling off or peeling. In addition, choosing the right primer can also have a big impact on the effectiveness of the brush. Therefore, it is recommended that when water-based paint is applied to plastic products, water-based paint should be selected specifically for plastics, and treated and brushed in accordance with the relevant operating specifications.

Can water-based wood paint be brushed with plastic?

Can water-based wood paint be brushed with plastic?

Water-based wood paint is usually suitable for decorating and protecting wooden furniture, doors and windows, etc., and is not recommended to be used directly for brushing plastic products. Because the surface of plastic is usually smoother than wood, there is not enough loose adhesive capacity to ensure the adhesion and durability of the paint film, and the paint film is prone to cracking, blistering and other problems. If you want to paint on plastic products, it is recommended to use a sales cherry paint or paint that is specially adapted to the plastic surface to ensure the effect and quality.

No, you cannot. In June 2007, Yue Wangkun, Secretary-General of China Coating Industry Association, said: "The domestic water-based paint industry needs to learn from foreign experience and expand market demand through standard publicity and consumption guidance; Water-based paint manufacturers not only need to closely combine technology research and development with social needs, but also unify product research and development speed, product types and consumer demand."

By 2008, China will ban the production and sale of solvent-based paints, and relevant documents have been issued during the Olympics to control the use of oil-based paints. These all show how long the vitality of oil-based paint can have in the future market, and also show the support of foreign developed countries and China for the development of water-based paint industry.

First, the problem of moisture, easy to reverse moisture in summer, some automatic spraying lines with good sealing, once the moisture, the water-based metal paint film after spraying, due to too much humidity, will destroy the water-based coating system, will produce sagging, so it is said to exhaust the air and drain the tide to protect the construction site.

Second, the cleanliness of the automatic line, many times customers complain about the cleanliness of the product, in fact, when making the coating, the cleanliness has been determined whether the cleanliness is qualified, like many customers say black spots, bubbles, should pay attention to the cleaning problem in the automatic line, because the air pressure generated during spraying will make dust, paint residues fly, resulting in poor cleanliness after spraying.

Third, the winter drying is slow, easy to sag, or the primer is not dry, affecting the flow of operations, water-based coatings include water-based metal pigments, the drying of aluminum silver paste itself is slow, it is more difficult to dry naturally in winter, how to prevent sagging and other phenomena? In fact, doing electric heating blast treatment and heating air circulation to the automatic line will be effectively improved.
