In recent years, with industrial workshop, large hospital, senior sports stadiums are increasingly demanding on the ground, epoxy floor coatings has become a coatings industry in one of the fastest growing of paint, epoxy floor coating has a clean smooth surface, strong resistance to chemical corrosion resistance, impact resistance, abrasion resistance and other characteristics, solvent into epoxy floor paint primer, midway and paint, primer, generally without additives, and the need to add additives to improve some performance and paint.
Defoaming agent: epoxy floor coating has a variety of surface active substance, blister easily, there are a lot of cement mortar substrate porosity, pore air replacement out in coating will be coating, the coating itself, the viscosity, the bubbles in the coating is stable, not easy eduction, defoaming agent must be added into the coating of these factors make bubble discharge faster, reduce needle, fisheye defects such as bubbles to eliminate system, can use organic silicon defoamer 6800680 1, deaeration speed, inhibit time is long, and won't produce shrinkage cavity, the silicon defoaming agent 6100, vinyl polymer, can effectively eliminate the bubbles, does not affect the painting.
Flow ping agent: solventless epoxy floor coating does not contain volatile solvent, solvent content, less coating of high solid content, surface tension, after construction of the surface wettability is poor, poor flowing property, the coating is easy to appear orange peel, brush marks, corrugated, surface defects such as shrinkage cavity, so need to add the flow ping agent to reduce the surface tension of the coating, to extend the time of flow, improve flow performance, flow ping agent 4184 polyether modified silicone, has the additional deaeration effect, good painting, good improve liquidity, transparency in the varnish, may just as well, the effect of shrinkage cavity and sticky.
Dispersant, epoxy floor coating product formula according to the requirements of performance and color fillers content high, the solid content is relatively high, in order to improve its dispersion ability, improve the quality of coating, increase coating performance, often to join the dispersant in the product formula, to avoid floating color, the phenomenon such as hair flower, KP110, KP111 copolymer solution containing acid group, apply to the stability of inorganic pigments, especially titanium dioxide, and can reduce the viscosity of the abrasive, suitable for grinding titanium pigment, scattered excellent results.
