The methods for distinguishing the authenticity of latex paint can be summarized as follows:
1. Observing packaging and labeling: Brands and specialty stores: When choosing latex paint from major brands, it is recommended to purchase from specialty stores and confirm if they have brand authorization. Anti counterfeiting code and authentication: Check if there is an anti-counterfeiting code on the packaging, and verify its authenticity by scanning the official anti-counterfeiting label or QR code provided. At the same time, pay attention to checking whether the latex paint has a national environmental certification certificate (such as the Ten Ring Certification) or other international authoritative certification (such as the German Blue Angel Certification), and verify it on the website of the relevant certification agency. Packaging details: Observe whether the lid of the barrel has been opened, and whether there are any scratches, deformations, paint peeling, or other marks. Genuine paint labels usually have metal wires and laser anti-counterfeiting coatings, and there should be no hidden knife edges on the label that cannot be completely peeled off and attached to other barrels. Label content: The label on the barrel should indicate relevant implementation standards, such as GB/T 9756 (Physical Properties) and GB 18582 (Environmental Performance), as well as possible other product labels such as "Ten Ring Certification".
2. Check product status: delamination phenomenon: After opening the latex paint, observe whether there is any delamination phenomenon. Poor emulsion paint generally has obvious layering, with more lotion in the upper layer and more solid in the lower layer. This kind of emulsion paint has more water content and poor hiding power and scrub resistance. A good latex paint should float with a layer of oily layered resin after opening the barrel. Color and texture: The color of the surface liquid should be close to transparent or white, rather than light yellow (light yellow may indicate excessive addition of chemical additives). Latex paint should drip in a straight line continuously, while inferior latex paint may clump and drip intermittently.
3. Feel the scent and touch: Odor: A good latex paint scent should be light, non irritating, or fragrant. If latex paint has a pungent odor, it may be due to poor quality or inadequate environmental performance. Touch: Dip your fingers in a small amount of latex paint, rub back and forth a few times, dry, and then try cleaning. The harder it is to clean, the better the adhesion, and the quality of latex paint may be better. Meanwhile, genuine latex paint should have a smooth and delicate feel.
By observing the packaging and labels, checking the product condition, and sensing the smell and touch, it is possible to effectively distinguish the authenticity of latex paint. When purchasing, it is recommended to choose legitimate channels and reputable brands to ensure the purchase of high-quality latex paint products.
