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...
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!
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...
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...
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, ...
Water-based wood lacquer can be used to apply. The characteristics of the brush method is simple, easy to master, fast coating speed, and can eliminate the brush method commonly seen bubbles and brush marks and other shortcomings. This is because the paint left on the surface of the wood is very thin and the pressure of the brush is high, which makes the air in the wood grain and micro hole easy t...

What are the obvious superior properties of super hydrophobic coating?Today let's have a look. 1.Self - cleaning function of superhydrophobic coating If the outer wall of th...
Composition of water bases adhesive 1.adhesive: also known as adhesive agent, after the surface treatment of two or more adhesive materials firmly connected together, and has a certain mechanical strength of chemical properties, such as epoxy resin phosphate copper oxide white latex. 2.Solid material (base material): determines the main physical, chemical and mechanical properties of rubber joints...
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...
Antifogging paint is a very practical paint, it can prevent fog, block people's sight, the basic principle and definition of antifogging paint what, let us know about it. Antifogging coating is a kind of functional coating.It is based on the hydrophilic group or hydrophobic group as the main component of polymer materials, and other additives and organic solvents in proportion to prepare, with ant...
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 ...
