Formulation design system for water based coatings - wetting leveling agent The wetting leveling agent can effectively reduce the surface tension of the system and significantly improve the construction effect of the waterborne wood lacquer.After the addition of the wetting leveling agent, the wetting property and permeability of the paint increase, the leveling property of the paint liquid is imp...
Rheological AIDS provide a leveling effect under high shear conditions, allowing the painted fluid to level out as quickly as possible, reducing brush marks and avoiding spatter. However, as the drying time goes by, this leveling effect weakens and the film is fixed, which can prevent the fluid from sagging on the vertical surface. Rheological additives can be divided into high, medium and low she...
Types, characteristics and applications of main rheological AIDS Variety Feature Application Methyl Cellulose The water system is thickened and has high efficiency, but the water resistance is not good, it is easy to be degraded by microorganisms, moldy and smelly, and the thixotropy after thickening with the system is strong, and the leveling property is not good. Generally not used in waterborne...
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 ...
Some surface properties of plastic substrate affect coating, and the properties related to coating mainly include the following aspects: Due to the characteristics of the plastic substrate itself, its smooth and compact, low surface energy is not conducive to the wetting and adhesion of the coating on the substrate. The crystallinity of the plastic affects the adhesion of the film, and its crystal...
The adhesion of the paint film is caused by the mutual attraction between the paint and the polar groups on the surface of the coated substrate, and the mutual attraction between the polar groups is based on the premise that the paint is well wetted on the surface of the coated substrate.Since the wet condition of the coating on the surface of the coated substrate depends on the surface tension of...
Sinograce Chemical - Jingangtai rafting trip On August 17th, Sinograce Chemical Marketing Center carried out the second quarter group building activities of the Rapids Warriors, blue sky and white clouds, green mountains and green waters, riding a rubber boat, leaping in the cool water, Sometimes light as a swallow, Now and then it gallops like a tiger, the event The thrills not only make the...
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...
Waterborne paint testing and standards:hardness Hardness is one of the most important physical properties of a coating. Coating hardness reflects the coating's ability to resist constant dents, scratches, scribes, and penetrations caused by a hard object. Testing the hardness of materials with different methods will give different results because the testing methods are for different amounts of ma...
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. ...
Thank you for the New Year gift of our company. In the New Year, we hope to make our products better and serve our customers better,Hope the performance increase day! Sinograce Chemical wish you a happy New Year!
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...
Color material gives printing rich and colorful colors,Connecting material as the carrier of color, also as a binder to make the color fixed on the substrate surface; Fillers give the ink the appropriate properties, so that the ink to meet the printing process of printing suitability.Ink should have a certain fluidity, and meet the requirements of the nature of various printing processes, can be q...
