Water-based epoxy floor coating marks cause and solution.

Water-based epoxy floor coating is a relatively popular floor coating in recent years, the biggest advantage of this coating is non-toxic and less odor, it is mainly the use of water-based epoxy resin and curing agent configuration, basically diluted with water, so VOC content and heavy metal content is almost 0, so the use of a broader range, but also bring positive effects on people's physical and mental health. In particular, the water-based epoxy flooring not only eliminates the polluting environmental problems of solvent-based epoxy flooring, but also eliminates the toxicity of solvent-free epoxy flooring. Therefore, water-based epoxy flooring can be widely used in life some production plants, office buildings, warehouses, laboratories and first floor floor, underground parking lots and other more humid environment of the floor coating, and because of the rich color of water-based epoxy flooring, so it also has a certain decorative effect
Water-based epoxy flooring paint construction is prone to problems - primer off, surface cracking, skin, due to poor strength caused by powder drop, etc. , we are mainly talking about water-based epoxy flooring construction when the problem of contact.
Real case: a gray of the customer, you can see that the problem at the joint is very obvious (right after 10 minutes of brushing)
1, testing whether different types of slurry can improve the connection problem
1, testing the following four common colors on the market in the customer base paint and Cody paste
(resin: curing agent - 5:1, color slurry addition: 15%, interval 1 0 minute brush plate)
in experiment scraper
experimental conclusion: through the interval of 10 minutes brush board comparison, (1), (2), (3), (4), (6) still have the problem of joints, but through the test color difference (E), from the data can be seen that the color difference is not large, indicating that color difference is not the main cause of the problem of joints; In other epoxy systems, testing has a connection problem, the phenomenon of high-gloss high black, and in Cody 9007-SI is relatively good, so the connection problem and the choice of color slurry type has a certain relationship

(Left: Resin: Curing Agent: 5:1; Right: Resin: Curing Agent: 10:1)Experimental Conclusion: Through experiments, the ratio of resin and curing agent is 10:1, the comprehensive performance of water-based epoxy floor coating is the best. Increasing the amount of resin can make the water-based epoxy floor coating application period extended, the film resistance, chemical resistance and moisture resistance and other performance has been improved, and increase the amount of curing agent can speed up the curing of the coating film, coating gloss, adhesion, wear resistance and solvent resistance also improved accordingly.
, whether the replacement of curing agent can improve the problem of connecting marks
The experimental conclusion: the replacement of suitable curing agents, but also can improve the problem of connecting marks. Water-based epoxy curing agent is one of the key groups to determine the final performance of water-based epoxy floor coating, can be better dissolved or dispersed in water, and stable in water, with epoxy resin has good compatible, at the same time the system's fluidization performance, application period, curing conditions And paint film performance can also meet the requirements of the use of floor coatings
1, the problem of joint marks and the choice of color slurry has a certain relationship, it is recommended to carry out experiments before construction, the selection of the most suitable color slurry
2, appropriate adjustment of resin and curing agent ratio can be effective Improving water-based epoxy flooring marks
3, selecting the right curing agent can also improve water-based epoxy flooring marks
4, water-based epoxy flooring coating system for two-part products, must be in accordance with the requirements when using Matching for feeding, and need to be after the reification, in order to better reflect the paint film performance
5, pay attention to the construction method, paint maturation time is not too long
6, paint construction, 24h should avoid people inside, According to the temperature conditions to do a good job
