Adding certain kinds and dosages of substrate wetting agent and adhesion promoter to the transparent base formulation helps to improve the adhesion of the paint film; the type and quality of the color paste are not only related to the phase of the color paste and the transparent base. Capacity also has a certain influence on the adhesion of the paint film. The thickness of the paint film, the dryi...
As the saying goes, three-point paint, seven-point painting. For water-based coatings, especially for water-based wood coating in the home improvement market, the level of coating technology has a direct impact on product use. In order to let everyone better master the water-based paint technology, we specially launched the water-based paint coating process series this week. The substrate treatmen...
Paint of water-based paint - Waterborne wood paint application process 2 Before using the soft brush, thoroughly soak it in clean water, remove excess water, and do not drip. The enamel paint should only reach half the length of the bristles.Brush as fast as possible, gently and smoothly brush the wood grain, and do not apply it back and forth repeatedly. Because the water-based paint dries quickl...
1.The tool Before using the soft brush, thoroughly soak it in clean water, remove excess water, and do not drip. The enamel paint should only reach half the length of the bristles.Brush as fast as possible, gently and smoothly brush the wood grain, do not apply it back and forth repeatedly, because the water-based paint is fast drying and the opening time is short, so it should be completed as soo...
Spraying construction paint film than brush paint film more flat. Spray with water-based wood paint should be added on the basis of the original paint 5% ~ 30% of the tap water dilute after use, for the viscosity of the paint water should also increase, the diluted paint after its coating a 4 cup viscosity should be around 18 ~ 20s. Dilute mix well should be static at least 20 minutes, until the b...
Polyurethane and general epoxy products application The use of the two products requires strengthened compressive tensile cement floors or floors and drainage ditches that are resistant to corrosion by strong acids and alkalis, such as chemicals, metallurgical plants, electroplating plants, power plants, pharmaceutical plants, PCB circuit board plants, paper mills, Hardware factory, printing and d...
1.Paper-based coating resins have been switched from natural water-based resins such as celluloses to synthetic resin emulsions such as carboxystyrene butadiene emulsions, polyvinyl acetate emulsions, and acrylic emulsions, among which acrylic emulsions have more excellent properties.However, the above resins are still difficult to meet the higher requirements for the development of coated paper. ...
Environmentally friendly water-based polyurethane waterproof coating is two-component,The component A is an isocyanate-terminated prepolymer obtained by polycondensation of polyether and isocyanate, and the component B is a colored liquid composed of a plasticizer, a curing agent, a thickener, a coagulant, and a filler.After use, the two components of methyl and ethyl are evenly mixed according to...
1.The cause of a back adhesion： (1)the paste itself anti-viscosity, especially in the wet weather easy to stick back; (2)After the printing is completed, it is packaged without perfect heat treatment; (3)adjust the slurry formula is not appropriate, adding too much transparent slurry easy to cause back adhesion; (4)transport or storage conditions are not good, in high temperature, high humidity co...
One, extinction principle General can be divided into physical extinction and chemical extinction.Physical matting, is the addition of matting agent, so that the coating in the film when the uneven surface, reduce reflection and achieve low gloss. Two, the kind of matting agent Coating common matting agent can be divided into organic matting agent and inorganic matting agent two categories. 1.Orga...
The choice of solvent In the printing ink manufacturing process, in consideration of the overall solvent system of the ink volatility, to improve the printing ink solvent release and reduce the solvent organic solvent residue, the use of solvents are often several volatile mixed solvents.In the printing ink manufacturing process, the main organic solvents are toluene, butanone, cyclohexanone, ethy...
In polyurethane waterproof coating construction often encounter some problems, so in the process of waterproof construction encountered different problems how to solve it?sinograce waterproof with you to learn the following, polyurethane waterproof coating construction common problems and solutions. 1. viscosity (1) coating itself viscosity is very large, construction effort. (2) if the client app...
In February 2020, during the severe situation of covid-19, Sinograce Chemical company dared to assume social responsibilities and made a modest contribution to the fight against covid-19. It donated alcohol and 84 disinfectant and other epidemic prevention materials to hefei primary and secondary schools and universities for daily disinfection of schools, with a total of 10 tons of 84 di...
Functions of antifogging coating: 1 Super hydrophilic self-cleaning function:anti-fogging coating also uses super hydrophilic silicon oxide film to form a super hydrophilic film between the painted surface and dirt, so that dirt and coated surface separation and the use of natural rain wash away the stolen goods under the action of gravity, to achieve the purpose of self-cleaning. 2 Antistatic fun...
Printing mucilage requirements The requirements of printing mucilage for manual plate printing Manual table printing is to press the screen on the fabric of the table for manual scraping, and the pressure extrusion on the scraper will print the glue through the mesh hole of the pattern part to the fabric. The shear stress of the binder is small, so thePrinting mucilageis required to have good...
With the development of The Times, people's invention is more and more magical, super hydrophobic coating is one of them, the use of the product can make the surface of the pollutants or dust can be gravity, rain or wind and other external forces automatically removed or degraded.What factors will affect the coating hydrophobicity, let us know about it. 1 hydrophobic principle The wettability of w...
