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...
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, ...
1.Introduction to silicone acrylic emulsion Silicon-acrylic emulsion is a kind of composite emulsion. It is a copolymer emulsion of organosilicone and acrylate.Acrylic resin has many excellent characteristics, such as weather resistance and light resistance, long time under ultraviolet irradiation is not easy to yellow。In addition, it also has flexibility, so it is often used as a leather finishin...
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...

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...
Cotton fabric is loved by everyone because of its good application characteristics such as soft touch, comfortable wear, moisture absorption and air permeability, but it also has defects such as poor elasticity and wrinkling after washing.In order to improve the shape retention of cotton fabric and to make it easy to maintain, it is usually treated with a hands-off finish.Etherified 2D resin finis...
On January 26, 2022, SINOGRACE Chemical Co., Ltd. will hold the year-end summary meeting and annual convention, and wish everyone a happy New Year.
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...
When waterborne polyurethane is used as adhesive, it must be mixed generally. Based on waterborne polyurethane, crosslinking agent, thickening agent, filler, plasticizer, pigment and other additives can be added. Other types of waterborne resin and water can be added.In order to obtain higher resistance to water Heat resistance and bonding strength, at present a lot of waterborne polyurethane syst...
Waterborne polyurethane adhesive is a kind of high-grade adhesive, with excellent flexibility, impact resistance, chemical resistance and wear resistance, the most important is its low temperature resistance.It has adsorption and chemical bonding effect on many kinds of materials. It can not only bond porous materials, but also bond smooth surface materials. It is widely used. Polyurethane adhesiv...
Water-based adhesives are environmentally friendly adhesives made of natural or synthetic macromolecule as adhesives and water as solvent or dispersant instead of toxic organic solvents that pollute the environment.Existing water-based adhesives are not 100% solvent-free and may contain limited vocs as additives for their aqueous media in order to control viscosity or fluidity.Advantages are mainl...
