Understand The Sealing Effect Of Epoxy Resin On Concrete

Jul 10, 2020

Speaking of epoxy resin, everyone must be familiar with it, it is more common in our lives, so how much do you know about it? Do you know its sealing effect on concrete? Is it not clear?

Selection criteria of concrete penetrant

(1) Wear resistance: It can solidify various components in concrete into a hard entity, increasing hardness and compactness. After use and aging, the wear resistance is increased to more than 6.

(2) Hardening: After treatment, the Mohs hardness is 8, and the Mohs hardness increases by 33.3.

(3) Impermeability: it can effectively penetrate into the concrete and react with it chemically, lock the pores inside, play a sealing effect on the concrete surface, and can effectively prevent water, oil and other surface dirt from entering the concrete.

Epoxy self-leveling is called "epoxy self-flowing floor" and "epoxy floor". It is a mixture of Jinan epoxy resin as the main material, curing agent, thinner, solvent, dispersant, defoamer and some fillers. Processed epoxy floor paint.

There are comprehensive standards for concrete specifications and testing. High-strength concrete should be avoided because high-strength concrete usually has a higher cement content and is more likely to shrink, making it difficult to perform surface treatment. The water content of newly poured concrete is more than the water content required in the chemical setting process, and some of the excess water will cause the concrete to shrink when free of concrete.

Therefore, the amount of cement and water in the concrete should not be excessive. The continuous consistency of concrete performance and on-site transportation are the keys to obtaining high-quality floors.

Epoxy resin

The concrete floor hardener enhances the weathering resistance, and ultraviolet rays and water spray have no adverse effect on the treated samples. It can effectively prevent the passage of chloride ions. Tests have shown that the treated floors will not be exposed to ultraviolet rays or water. It is affected in the fog, effectively increasing the life of the building.

Epoxy floors are designed according to different application requirements: such as thin layer coating, 1-5mm thick self-leveling ground, anti-skid and wear-resistant coating, mortar-type coating, anti-static, anti-corrosion coating, etc. The concrete seal curing agent is derived from the calcium silicate compound (C-S-H) produced by the silicon and calcium in the cement component of the concrete under the action of water. C-S-H is the substance that plays a major strength role in concrete. Concrete seal curing agent is a concrete seal hardening agent is a colorless transparent liquid material, easy to use, non-toxic, non-flammable, strong penetration, sealable concrete, in line with all VOC rules.
