Performance: the emulsion and the hydrophobic pearlescent powder are tightly combined, waterproof good; the emulsion content is high, the film forming property is good, the surface is compact, silver foil primer contains the formaldehyde removing material, and obtains the national patent, the whole process of degradation of formaldehyde is pure taste degradation, unlike the market degradation of formaldehyde has a sour taste, anisotropic structure of silver foil paint, different perspective observation has different perception; Features: good waterproof, anti-pollution, anti-formaldehyde up to 90.2% , environmental high shine gloss; dominant role: the wall is not susceptible to moisture, wall mold, drum, powder and other problems; good scrub, easy to take care of, sweeping all the wall oil pollution problem, net smell degradation of formaldehyde rate reached 90.2% , safe to stay, used as smallpox/background, so that the whole house light up, more advanced; Evidence/citations: Spray water through a spray bottle on the wall surface in a form of atomization that will slowly condense into droplets and flow down. The spot uses the watercolor pen, the soy sauce sprays on the wall, uses the wet towel to carry on the scrubbing. At the scene, he was given a formaldehyde testing instrument to do experiments on a board that was swiped with Cadbury's products, and a board that wasn't swiped with Cadbury's products. The test data showed the light of the mobile phone onto the sample board, guiding the customer to look at the wall from different angles, create multiple feelings, and with the sales staff to explain, so that customers in the mind to form a picture full of artistic atmosphere.
