Polyamine modified epoxy coating crosslinking agent
Polyamine modified epoxy coating crosslinking agent
Anhydride in water will break down, do not suit as crosslinking agent of waterborne epoxy resin, and water-borne epoxy floor coating used in room temperature crosslinking, and most commonly used water-based epoxy crosslinking agent for multiple amine or its modified products, using its active molecules of amino epoxy reaction of epoxy resin and hydrogen molecules.
Multiple amine modified epoxy crosslinking agent has the following three types: the first is a fatty acid was prepared by multiple amine and amidation of polyamine, the second is by dimer acid condensation of polyamide with multiple amine, and the third is by multiple amine and epoxy resin addition of polyamine - epoxy adduct.
These three multiple amine modified epoxy crosslinking agent are used in multiple amine in nonpolar groups in molecular chain made of the modified polyamine crosslinking agent with amphiphilic structure, to improve the compatibility with epoxy resin.
After the concrete base material processed and clean coat can be carried out on (roller coating or brush), roller coating or brush should be uniform, thickness, the bottom can have certain waterproof qigong, can enhance the strength of base material and increase the adhesion of coating to the substrate.
The quartz sand and quartz powder are added to the water-based epoxy slurry in the water-based epoxy coating, which is evenly coated with a trowel to increase the thickness and the compressive strength of the coating.
Besmear after use sand paper burnish of floor and waterborne epoxy coatings (paint) and quartz powder with a number of be bored with child construction in accordance with the actual need, require smooth and no holes, no batch of knife is printed and sand mill.
The roller can be used to paint the surface of epoxy floor coating in two ways. After finishing, the whole floor is required to have a soft, clean and uniform color, no empty drum.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Raw material ：
TDA industrial, Sichuan production
Ethylene (Et) polymer grade, Shanghai production
TEA industrial imports
The surface layer should be closed for 24 hours, so as to avoid the effect of clean and smooth surface. 3 days before valentine, a complete maintenance after 7 days before officially put into use, will be subject to 25 ℃, low temperature should be moderately open).
Water-based epoxy floor coating with a solvent epoxy floor coating is the performance of current water-borne epoxy floor coating can be applied in the pharmaceutical, food, hospitals, textile, chemical industry, electron, etc., the production workshop, office building, warehouse, laboratory floor coating, especially suitable for the first floor, basements, underground parking and other relatively sand emery wear-resisting flooring, emery, copper ore, pyrite ore, steel slag sand, quartz sand, iron sand, steel grit, iron steel grit sand is used as a nozzle cut the sand material, filtering and abrasive.
Suitable for industry: sandblasting/spray paint, granite rock cutting, ocean-going ship manufacturing repair, oil and gas pipeline; Factory maintenance and steel production. Scope of application: surface treatment of steel parts and non-iron workpieces before painting, abrasive cutting of water gun; Etching of stone and glass; Cleaning of concrete and brick materials; Cleaning of sensitive area of workpiece; Adhesive and coating abrasive.
Spray sand anti-rust series; Is given priority to with 8-12 mm, its performance characteristics: granular solid, good toughness and sharp edges, small broken rate, low ash content as rust removing material recycling for many times and do not produce contains SiO2 dust hazard operator's health, it replaces the previous pickling corrosion protection for the inconvenience, river sand derusting fewer recycling, steel shot, iron ore, rust removal cost is large, the price higher adverse factors, is one of the steel structure, steel, pipe, pipe, iron tower, long bridge, plastic spraying, shipyards, ideal anticorrosion material surface treatment.
Floors: 10-20 eyes, 20-40 eyes, 40-70 eyes. Features: the emery abrasive floor has high strength and abrasion resistance, anti-pressure, anti-penetration, anti-static, anti-corrosion and concrete entering into the process, the construction period is short, and the effect is better.
