Water - based coating formulation design system - matting agent Matting agents are additives used to control the gloss of waterborne wood coatings to meet the broad needs of mainstream matt paints in today's market.The extinction mechanism of the matting agent can be arranged in an orderly manner on the surface of the coating film, so that the surface of the coating film is uneven, causing the lig...
Waterborne paint formulation design system - pH regulator Waterborne wood coatings may also need to adjust the pH when necessary.Most emulsions or aqueous dispersions have been adjusted to a pH of 8 to 9 when they are produced, eliminating the need for pH adjusters when making paint.If the pH value is different, add 0.05% to 0.1% of the pH adjuster during the paint making process, and adjust the p...
In the solid paint, white paint is taken as an example. The amount of titanium dioxide should be sufficient to ensure that the paint film has sufficient capping power. The amount of titanium dioxide should not be lower than 13%, but it is not necessary to be higher than 22%. The situation is the same as solvent-based white paint. Fillers may be added or not added. However, a small amount of filler...
Wood coating process 1.There are many large holes in the hard wood, putty or hole adding agent to flatten; 2.Apply closing primer after hole filling； 3.If you need to deepen the surface texture of the wood and highlight the wood grain, you can apply the closed primer and apply the water color； 4.After conditioning the wood grain, apply two closed primer； 5.Finish with top coat. Sinograce Chemical ...
The third step in the treatment of water-based paint coated substrates is sealing. The role of the water-based putty is to make the surface of the substrate such as wood not very regular and smooth and minor defects and defects, such as pores, fine cracks, pits, joints and concrete, to reduce the surface roughness and increase the flatness.The requirements for water-based putty are good adhesion a...
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. ...
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...
Anhui Sinograce Chemical Co., Ltd Polyurethane condoms, known as condoms, are made of polyurethane condoms, similar to latex condoms. Polyurethane was applied to condom production in Japan, until the emergence of China's Nakagawa 001, which broke Japan's monopoly on the production field. Because the common latex condoms on the market are thicker and polyurethane has good ...
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...
According to the current development trend of waterborne polyurethane coating, green polyurethane coating technology is mainly divided into two categories: waterborne polyurethane coating and solvent-free polyurethane coating.Among them, solvent-free polyurethane coating mainly contains polyurethane hot melt adhesive coating and light curing polyurethane coating.Waterborne polyurethane (WPU) is a ...
PCL is a fully degradable polymer with good biocompatibility. When introduced into waterborne polyurethane, it can make waterborne polyurethane have shape memory.Shape memory waterborne polyurethane has attracted wide attention for its shape memory function, temperature sensitivity and moisture permeability. PCL3000 PCL4000 was used as the soft segment, and toluene diisocyanate was used as the har...
Non-stick pot is cooking will not stick to the bottom of the pot, because the bottom of the pot uses a non-stick coating, the common non-stick can best have teflon coating and ceramic coating. The non-stick pan overcomes all the shortcomings of the traditional pot, easy to clean, a light wipe is clean, non-stick pan can easily fry food without sticking to the bottom, can minimize the oil, the kitc...
Waterborne polyurethane is often used in the preparation of waterborne coatings because of its excellent film formation and adhesion, excellent flexibility and wear resistance.However, water-based polyurethane dispersion contains a lot of surfactant, easy to produce bubbles, and because of the special properties of water-based polyurethane, it is necessary to use the characteristics of water-based...
Surfactants are a large group of organic compounds, their properties are very characteristic, application is extremely flexible, extensive, has great practical value. Surfactants have been as emulsifier, detergent, wetting agent, penetrating agent, foaming agent, solvent, dispersant, suspending agent, cement water reducing agent, fabric softener, leveling agent, fixing agent, fungicide, catalyst, ...
If you've ever used a non-stick pan, you know how good it is.You don't need any cooking skills to get a spoonful of rice without the rice crust and a full fried egg for breakfast. It also cooks healthier with less oil and less paste. However, in recent years, "non-stick pans are toxic" claims abound; Also many people see the bottom of the non-stick pan is scratched, showing mottled lines, always w...
