Water-based coating formulation design system - preservative Water-based wood coatings are water-based systems that are easier to bring into bacteria during production and are more susceptible to microbial degradation during storage. Therefore, the type and amount of preservatives should be properly added during formulation to prevent system and coating corruption.From the perspective of environme...
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...
To master waterborne wood coatings and coatings, you must be familiar with the characteristics of wood. In this way, we can find the root cause of the problem in the painting process and make the necessary preventive and treatment measures. Wood is a natural fiber material, seen from the cross section of the trunk, it is a uniform material composed of layers of different materials, with many textu...
The steel is subjected to different degrees of corrosion conditions in different operating environments. According to the corrosion conditions, the environmental conditions used by the steel are divided into four grades: Steel use environment and corrosion conditions Steel use environment and corrosion conditions Definition Performance Requirements Coating Effect Harsh conditions Products used in ...
How to deal with the surface of water-based anti-rust paint before painting As the saying goes, "seven-point paint three-point paint." The correct handling of the substrate can have a major impact on the performance of the coating. Waterborne anti-corrosive paint is no exception. During the processing, transportation and storage of the workpiece, the surface often has the moldi...
In recent years, with the increasing awareness of environmental protection and the importance and legislation of governments in environmental protection, more and more anti-rust paints are turning to water-based.Many foreign customers have begun to demand waterborne anti-corrosive paints for domestic suppliers. After sinograce chemical successfully launched our water-based anti-corrosive paint|wat...
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...
Current problems with waterborne polyurethane adhesives: (1) Low solid content: At present, the solid content of water-based polyurethane (WPU) can reach 45%. Fewer systems lead to higher drying and transportation costs. Increasing the solid content leads to an increase in the viscosity of the system, which makes emulsification and dispersion difficult. Reduced emulsion stability. (2) Slow drying ...
At present, two-component waterborne polyurethane has been widely used in leather, textile dyeing AIDS, adhesives, foam materials, coatings and other fields. With the continuous development of two-component waterborne polyurethane scientific research, it is gradually replacing solvent polyurethane as the medium to occupy the dominant position in the market. One: leather China's leather resources, ...
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 ...
Plasticizer is widely used in industrial production of polymer materials auxiliaries, also known as plasticizers. All substances added to polymer materials that increase polymer plasticity are called plasticizers. The use of plasticizer can improve the properties of polymer materials, reduce production costs and improve production efficiency. is a class of important chem...

Appearance Dark grey liquid Solid content(% ) 50±1 PH 6-9 softening point(℃) 45-55℃ Proportion（g/cm3） 1.06±0.02 viscosity（mPa.s） 1000-2000（Viscosity can be adjusted） Application Area Automobile interior adhesive ...
Water based wood lacquer is mainly made of waterborne acrylic acid and polyurethane and refined by strict production process standards. It is suitable for the protection of indoor wood and wood products, and can play the role of decoration, protection and service life extension.Waterborne wood lacquer uses water as diluent, does not contain benzene and other harmful substances, non-toxic...
What are the uses of waterborne acrylic emulsions? Waterborne acrylic emulsion is used as finishing agent for silk fabrics and leather Water based acrylic emulsion is used as finishing agent and treating agent for photographic printing paper Waterborne acrylic emulsion has good sealing performance on wood grease and tannic acid, used as transparent sealing primer for wood,...
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 ...
Solvent selection In the printing ink manufacturing process, considering the overall solvent system of the volatile ladder, improve the printing ink solvent release and reduce printing solvent organic solvent residue, the solvent used is often a mixture of several volatile solvents. In the printing ink manufacturing process, the main organic solvents are toluene butyl ketone cyclohexanone ethyl ac...
