Second, check the amount of weight: According to industry insiders, different paint packaging specifications vary, the weight is also different, consumers can use a simple method of purchase, knowledge of superiority and inferiority: shake out each tank, if shaking it A "click" sound indicates that the serving size is insufficient or volatile.
Three smells: After the lid is opened, the truly environmentally-friendly latex paint should be water-based, non-toxic and odorless. Therefore, if the user smells pungent or industrial flavor, it is not ideal. After a period of time, the surface of genuine latex paint will form a very thick and elastic Oxide film, which will not be easily cracked, while inferior products will only form a very thin film that is fragile and has a spicy smell. Mix the latex paint with a wooden stick and pick it up with a wooden stick. The high-quality latex paint will become fan-shaped when it goes down. Touch with your finger, genuine latex paint should feel smooth and delicate. Real latex paints do not have irritating odors, and the low-grade water-soluble paints of counterfeit latex paints may contain formaldehyde and therefore have a strong pungent taste.
Four views of its shape. The high-quality paint has a colorless or yellowish color in the protective rubber solution layer. There is usually no floating surface.
Five according to the choice of room. The function of latex paint is very important. It is necessary to select the latex paint according to different parts of the brushing. For example, the latex paint used in the walls of bedrooms and living rooms requires strong adhesion, delicate texture, good resistance to differentiation and breathability, and kitchen and bathroom facilities. Latex paints should have waterproof, mildew-proof and washable properties. Bedrooms use polyvinyl acetate (commonly known as latex paint), but kitchens, toilets, and balcony roofs that are prone to moisture should be chosen for scrub-resistant coatings, strong ethylene-propylene or styrene-acrylic latex paints.
Six watch VOC. The VOC of a coating refers to the total amount of organic compounds contained in the coating. The volatilization of organic substances can cause harm to the environment and the human body. The amount of these solvents should be minimized. However, at the same time, it should be noted that these organic compounds are the main components of the main film forming materials for coatings, and they cannot reduce the VOC content blindly, because this may cause the viscosity of the coating to decrease accordingly, resulting in the powder falling off and blistering. Cracking and low scrub resistance occur. Experts said that if you do not consider the quality of the paint, simply reducing the VOC content is a simple process. For example, adding more water to the paint will reduce the VOC content. Therefore, some small paint manufacturers can make VOC very low, but the quality cannot be guaranteed.
Therefore, as long as it is in line with national standards of qualified environmental products can be assured to buy!
