(Summary description)1. Be clear about what resin is used to make water-based paint
The classification of water-based resins is very clear. The properties, functions, and prices of various resins are very different or very different, which directly affects the quality, performance, effect and cost of water-based paints. Be sure to choose products that meet your needs.

1. Be clear about what resin is used to make water-based paint
The classification of water-based resins is very clear. The properties, functions, and prices of various resins are very different or very different, which directly affects the quality, performance, effect and cost of water- based paints. Be sure to choose products that meet your needs.
 
Second, the most basic inspection of water-based paint products
1) Taste: must not have a strong pungent taste, a strong alcohol smell, or a strong offensive odor, because the taste is determined by the additives. Beware of fraudulent and technically unacceptable water-based paints.
2) Emulsion properties: It is generally transparent to milky white. Do not judge the quality of the product based on its consistency (thickness). After all, the consistency is determined by the thickener with lower cost. The key is to match the color and viscosity of the sample. .
3) Dispersibility: Look directly at the product emulsion in the package. It will not be precipitated and dispersed uniformly as top grade. This can reduce the difficulty of use or avoid product deterioration, except for some specially designed products.
 
Testing and inspection of water-based paint and its film properties
1) Abrasiveness: Drying sandpaper requires powder and non-stick sandpaper, otherwise, the consumption of sandpaper will increase a lot, and the flatness of the polished film will decrease, affecting the quality of painting.
2) Resistance to yellowing: painted on glass or white porcelain, after drying, exposed to sunlight for more than 3 days or under UV light for more than 4 hours, observe the yellowing of the paint film, the smaller the yellowing The better, the better without yellowing.
3) Surface drying time: temperature ≥5 ℃, humidity ≤80%, under normal air circulation conditions, surface drying time ≤10 minutes, otherwise it is prone to sticky dust, slow drying and difficult to grind, longer recoating time and extended operation process, etc. The disadvantage is that the longer the surface drying time, the more difficult it is to apply.
