Epoxy floor coatings have excellent adhesion to concrete and other substrates, low curing shortening rate; especially, water-borne epoxy floor coatings have outstanding water resistance, oil resistance, acid and alkali resistance, salt spray corrosion resistance and other chemical characteristics, but most of the solvent in epoxy floor coatings is harmful to the human body, MDA, TDl these characteristics Cancer substances will remain in the epoxy floor and slowly evaporate. This is the fundamental reason why Americans do not do epoxy floor paint, so epoxy floor paint is not suitable for home decoration. Nowadays, it is prevalent to polish concrete golden diamond ground with Nalute concrete sealing and solidifying agent. The products are characterized by no (TVOC-free, non-toxic, seamless), anti-dust, anti-skid, waterproof, anti-compression, anti-permeability, anti-aging, anti-corrosion, anti-conflict and anti-scratch), high-end specification and multi-choice of styles. 1. Waterborne epoxy floor paint, waterborne and oil-based floor lacquer.
Experts introduced that the products supplied by epoxy resin and curing agent generally have a higher viscosity, in order to achieve the ultimate practical application requirements, often need to reduce viscosity, improve the construction function. The general oil-based epoxy resin AB compositions with chemical solvents as dilution components have been widely used, but organic solvents are toxic, costly, and have outstanding potential safety hazards in production, transportation and construction. The waterborne epoxy resin and the matching waterborne epoxy resin curing agent completely take water as the dilution component, does not contain the solvent and the auxiliary solvent, is non-toxic, tasteless, does not have the residue, thoroughly solved the above oil epoxy resin system flaw and the lack.
The water-based and oil-based systems are completely different from each other, and the products are still epoxy resins in nature. Therefore, the water-based and oil-based series of products used as epoxy resins are produced in raw materials of water-based epoxy resins and water-based epoxy curing agents; the processing and manufacturing of coatings, adhesives and other products; the coating and construction of finished products; the final products. There are many differences in physicochemical functions and even completely opposite ones. In waterborne epoxy systems, waterborne epoxy resins are generally made of waterborne epoxy resin emulsion by means of general specification for grafting and emulsification of oil-based liquids or solid epoxy resins. The emulsion is sold in roughly 50% solid fraction. Generally, waterborne epoxy emulsion is directly used as a component of B. It does not require dilution, nor does it require grinding, color matching and additives in emulsion. Two, can the construction of waterborne epoxy floor paint save the middle coating?
We know that primer and topcoat are essential in the process of epoxy floor paint. One of the most common misconceptions about epoxy floor coatings is that the top coat is palpable and the primer layer can be understood, but it's not a big problem if the middle coat is not done, and it saves effort and money.
In fact, we can say that the epoxy floor paint in the construction process, if only do the bottom and surface layer, less than the middle coating, then, such epoxy floor is only a semi-finished product. The middle coating is very important to the construction of epoxy floor. It is also a crucial step in the three process. The reasons are as follows:
1, enhance wear resistance. This is decided by the nature of epoxy floor paint. Epoxy floor paint is a kind of film-cured floor paint. It completes its maintenance mission by forming a maintenance coating on the concrete surface, just like our skin. But from the film forming, it can be worn. The thinner the floor paint works, the easier it is to be worn out. And the middle coat is sandwiched in the primer and top coat center, improve the wear resistance of epoxy floor engineering, the use of key years.
2. Add thickness. After the general floor paint primer and topcoat construction, only 0.2-0.5mm coating will occur, so not only wear resistance is very poor, but also give people walk on top of the experience is very poor. This everyone should have a feeling, the thick epoxy floor project must be flexible, walking on it is very comfortable, fall will not be very painful.
3, reduce costs. Since the coatings are not required to undertake the mission of protecting against various harmful substances, that requirement can actually be reduced a little bit. And the middle coating is in the center of the epoxy floor coating, so the toner can be saved. Therefore, middle coating is cheaper than topcoat and primer.
