Product Introduction
Waterborne epoxy curing agent K series products are non-ionic water-soluble modified epoxy polyamine adduct curing agents. The curing agent is
Water is the diluent, does not contain alcohol ether solvents or co-solvents, and does not contain acetic acid neutralizers. It can emulsify ordinary low molecular weight liquids
Oxygen resin can be used in conjunction with high molecular weight epoxy resin emulsion. Through formula design, water-based rings with excellent quality can be made
Applications
1) Concrete surface: industrial floor coating suitable for ordinary or wet substrate surface
2) Matching sealing primer: a matching primer suitable for wet substrate surface. Exterior wall sealing primer, polyurethane, polyurea waterproof coating
Sealing primer, etc.,
3) Metal surface: It can be used as an anti-corrosion coating for steel, aluminum and other metals for bottom, middle and top coating.
Three, product characteristics
1) Water is used as diluent, no alcohol ether solvents or co-solvents
2) It has good adhesion to various substrates (such as concrete, metal and daily coating), and can seal part of the alkali gas of wet concrete
And water vapor
3) Good acceptance of pigments and fillers, can be used with cement mortar, and the coating film has excellent chemical resistance
4) Paint tools and construction tools can be directly diluted with water
5) It has early resistance to water stains and scrubbing.

Five, use reference
1. According to the technical indicators of the curing agent, choose the appropriate epoxy emulsion or standard liquid epoxy resin. Usually liquid epoxy
Resin as the main agent can obtain better economy and wide applicability; if the epoxy emulsion is made of high molecular weight epoxy
Prepared by resin, you can get a shorter surface dry time
2. Generally, in order to obtain a well-cured paint film, the national chemical temperature should be above 10ºC and the relative humidity below 80% is declared.
When painting, if the solid content of the system is low, the one-time construction should not be too thick, otherwise a well-cured coating film will not be obtained.
4. In order to meet different requirements, the dosage of curing agent can be changed within 15% of the theoretical dosage value. When the dosage is high
Higher gloss can be obtained; better water resistance can be obtained when the dosage is low.
In order to obtain a well-cured coating film, the construction environment should maintain air circulation. When constructing in places with no air circulation, please use
Take forced ventilation measures
6. The formula composition and curing conditions of the epoxy coating prepared with the waterborne epoxy curing agent and epoxy resin are determined by each user.
