Waterbased polyurethane paint for crosslinking agent
2017-3-9 16:06:11
Waterborne polyurethane paint for crosslinking agent, two-component waterborne polyurethane coating glossiness and resistance to a great extent, depends on whether the hardener can fully and evenly spread in the water phase.
With an ion sulfonic acid ester groups (are connected by chemical bonds and isocyanate molecules), improved the diffusivity of cyanate ester, its effect is very good. In terms of hardness and drying speed, with the deployment of the coating is by no means inferior to solvent coating system deployment. Their chemical resistance is much stronger than based on traditional hydrophilic modification of isocyanate waterborne coatings.
New products on the proportion of the sulfonate group content is different. Hydrophilic modification has reached minimum. The diffusivity and standard products as well, but the performance of the composite coatings were far superior. Which means of coating material in the system even more easily than the two-component polyurethane system based on solvent to remove graffiti.
Surface of the strong acid resistance and oil resistance, and for some plastic has better adhesion and rapid drying are also the advantages of the system. These characteristics make it be used for railway vehicles, cars, industrial products and high quality furniture paint ideal hardener.
Coating can rapid drying, and therefore easy to stir with the hand, making it more than suitable for vehicle repair surface and the other is not able to use complex mixing equipment and industrial processing of all standard in the field of application. Its superior diffusivity can form colorful coating.
Contains only a very small proportion of hydrophilic modification of sulfonic acid ester groups, although very low viscosity, but there are still a good diffusivity. Surface coating is an important application of this kind of curing agent. The product can be used in the system of the character of structure has good resistance to chemical, and does not discharge any volatile organic compounds.
For wood coatings has a variety of single component waterborne polyurethane resin to choose from. Find the best technology not only need to have a thorough understanding of the performance of resin, and also have to know about end use wood coatings, such as floor, kitchen cabinets, furniture, interior Windows and doors and outdoor wood use.
Although one-component waterborne resin offers a good balance between the required performance, through cross-linking agent is added in the formula can improve the performance of water-based paint, remember it is also important. Proper crosslinking agent of choice depends on the purpose of the polyurethane dispersions.

Research and experiment can make the resin selection process smoothly.
Formula for the designer, this means that saves a lot of time, money and resources. And it will also make it easy to select the best resin process, the optimal resin can make the specific use of wood coatings to obtain the required performance.
Coatings are usually classified according to the chemical characteristics of different, namely chemical classification, can be divided into inorganic pigment and metal powder, organic pigments, and there are two main types of fluorescent paint, etc. Inorganic pigments with white titanium pigment, black for carbon black, such as paint black FBRN; Metal powder to have certain fineness of copper zinc alloy powder and aluminum powder.
Organic pigments for does not have water soluble groups on the molecular structure of azo dyes, metal complex dyes, phthalocyanine dyes and VAT dye, etc., in general, red, blue, sauce, yellow paint for azo dye, bright blue, bright green coating for phthalocyanine dye, golden yellow, pale purple coating for VAT dye.
Fluorescent pigment is special varieties of organic coatings, the occurrence of the fluorescence is mainly due to the dye molecules containing fluorescent groups, and by the conjugate system through, they absorb the shorter wavelengths of the visible light, so as to reflect the longer wavelengths of light, they absorb the energy of the incident light, make the one part of the energy into light energy, thus increase the amount of reflected light, the brightness and strength significantly increased, the fluorescence.
