Application of additives in epoxy resin wear-resistant floor paint engineering

China Coatings Online News Information: Epoxy clean wear-resistant ground coating on the coating film leveling requirements are very high, especially in the case of thick film, not only to make the coating film in the active period of full leveling, but also requires the rapid discharge of bubbles in the wet film without defects on the surface, therefore, leveling, defocing and other additives selection and dosage is a very critical factor. On the one hand, the increase in the dosage of such additives will reduce the surface tension when coating the film into a film, is conducive to film self-leveling and deblistering, on the other hand, the excessive addition of such additives will introduce insoluble substances, the resin and filler bonding adversely affected.
epoxy resin wear-resistant ground coating should consider the choice of suitable additives, all additives are added to improve construction and improve the performance of the coating for the purpose. Here are a few major additives for a brief introduction:
1) desiccant epoxy resin wear-resistant ground coating contains a variety of surfactant substances, easy to foam; There are many pores in the cement mortar substrate, and the air in the pores will be replaced by the coating and left in the coating film. Ground coating in the construction of mechanical stirring and scraping plate will make a large amount of air into the coating film; And the paint itself has a large viscosity, bubbles in the coating film stable, not easy to discharge, these factors make the coating must be added decogant to accelerate the discharge of gas, reduce needles, fish eyes and other defects.
2) leveling agent solvent-free epoxy resin wear-resistant ground coating without volatile solvents, solvent content is small, the solid content of the coating is high, the surface strength is large, after construction of the substrate moisture is poor, the leveling is not good, the coating film is prone to orange peel, brush marks, ripples, shrink holes and needles and other surface state defects. Therefore, the leveling agent must be added to reduce the surface pressure of the coating, extend the flow time, improve the leveling performance.
3) Dispersant epoxy floor coating product formulation according to performance and color requirements, pigment, filler content is high, solid content is relatively high, in order to improve its dispersion capacity, improve film quality, improve coating performance, usually in the product formulation to add dispersants, to avoid the production of floating color, flowering and other phenomena, improve and improve coating performance.
