Coating with mixed crosslinking agent
2017-3-1 17:32:18
Coating with mixed crosslinking agent, with VESTANAT EP - MF 201 and intermiscibility polyol compound, two-component formula are obtained.
Two types of crosslinking agent suitable blending ratio will be determined. As a result of the action of interpenetrating networks, paint scratch resistance, stain resistance and chemical corrosion resistance and other performance can adjust according to need, without having to add polyisocyanate crosslinking agent. The resulting coating is a kind of NISO system, low VOC content, which is decided by the performance of the polyols.
A two-component polyurethane (left) and a two-component VESTANAT EP - MF 201 recipe (right) on the basis of the comparison results. Two systems are applied to wood, scratch resistance test with a modified friction fastness tester. Experimental results show that with the unmodified can see a lot of two-component polyurethane processing wood surface and apparent Nick, and use VESTANAT EP - MF 201 formula on the basis of the processing of the surface of the wood can't see the scratch, and the finish and appearance.
The product can be used for wood coatings not only, still can be used in plastic coating. The scratch resistance, stain resistance and chemical corrosion resistant coating can also be well applied to sports supplies and automotive industry. Because of the new crosslinking agent technology skeleton is variable, so can free in the production of multi-function customization crosslinking agent.
VESTANAT EP - M series is a kind of silane/ammonia ester mixed crosslinking agent, can be used to produce all kinds of substrate of multi-function, the scratch resistance of coating. The characteristic of the modified room temperature curing, made possible by the. The crosslinking agent and can be used in wood coatings, can also be applied in some other areas. The technology to the preparation of high-performance NISO coating, even more than the performance of the polyurethane. In addition, through the replacement of traditional isocyanate curing agent of two-component polyurethane coatings, and the scratch resistance of coating performance improved significantly.
Coating formula design refers to according to the base material, the purpose of the coating, coating performance, use, construction environment such as the choice of coating components and determine the relative proportion, and on the basis of this puts forward the reasonable production process, construction technology and curing methods.
Coatings generally consists of film forming matter, pigment, solvent and diluent, additives, coating after construction, with the evaporation of the solvent and diluent, film former, dry film. Film forming matter can be separate into film, also can bond pigment substances such as film together, so also known as the binder. It is the basis of the coating, often referred to as basic material, paint, and have been.

Coating additives, also called paint accessories, auxiliary materials, the mixture of coating can improve the coating performance, promote the film formation. A lot of more phyletic, including crosslinking agent, agent, toughening agent, emulsifier, thickener, pigment dispersing agent, defoamer, leveling agent, skinning agent resistance, flatting agent, light stabilizer, fungicide, antistatic agent, etc.
Is indispensable to paint coating auxiliaries components, it can improve the production process, keep the storage stability, improve the construction conditions, improve product quality, endowed with special function. Correctly choose additives can reduce costs, increase economic benefits.
In addition to the main film-forming material, fillers, solvents, an ingredient added to the coating to, can make the coating or coating of a particular performance have obvious improvement effect of the material. In the coating formula dosage is very small. Is mainly a variety of inorganic compounds and organic compounds, including polymer.
Their names are mostly based on function features of its name. Improve coating production technology has a wetting agent, dispersing agent, emulsifying agent, defoamer, etc. Improves performance of the paint storage and transport has anti-settling agent, anti skinning agent, preservative, freeze-thaw stability agent, etc.
Improve the coating performance and construction to prevent paint film morbid sags have proof agent, flow ping agent, floating color hair flower preventing agent, antifoaming agent, thickening agent, etc. Improve the coating performance and give special performance of uv absorber, light stabilizer, flame retardant, antistatic agent, fungicide, etc.
Coatings additives and can be divided into oily coating additives and coating additives. Comply with the world is becoming more and more attention to environmental protection, the development of waterborne coatings additives have the leap development. More and more new environmental protection type of auxiliaries, is becoming more and more widely applied, is the mainstream of the future development direction of coating.
