Anonymous users2024-02-16As a high-performance, high-value-added adhesive, epoxy resin adhesive is highly valued by the industry, but at the same time, counterfeit and shoddy products are often patronized. Therefore, we can identify it by the following chemical methods. Method 1:
The sample is dissolved in sulfuric acid, and then concentrated nitric acid is added, and a large amount of sodium hydroxide solution is poured into it. The second type: drop 5 drops of concentrated nitric acid on the resin adhesive film, move the reactant into the test tube after a few minutes, add 6ml of acetone and then add potassium hydroxide ethanol solution to make it alkaline, if it turns from red to purple, it indicates that it contains epoxy resin glue containing bisphenol A type, this method is also intuitive; Method 3:
Take the adhesive film or glue solution, p-phenylenediamine and 8ml of sample water, boil for 8min, if it is epoxy resin, the solution is peach....

The national standard sail of phenolic epoxy coating is: brown-yellow viscous liquid, golden yellow surface, smooth and uniform, normal color after soaking, no whitening, falling off, no heterochromatic sensitive land odor, no mixed bridge car.
Epoxy phenolic paint is composed of epoxy resin, code lead phenolic resin, pigment filler, solvent and additives, which has excellent characteristics such as corrosion resistance, heat resistance, abrasion resistance, etc., and is used in chemical corrosion environments, storage tanks, container inner walls, equipment protection, etc. Epoxy phenolic paint is a two-component coating, including a main paint and a hardener, which is used in strict proportions. Thick delay coating construction can be carried out thick coating construction, a coating paint film thickness is large, improve the anti-corrosion effect of the coating, heat-resistant characteristics of the paint film has excellent heat resistance characteristics, dry heat resistance 300, the coating film is intact, to prevent the substrate from high temperature oxidation.

Anonymous users2024-02-13When decorating, we use a variety of coatings, and the types of coatings on the market are a lot of regrets, but some people use solvent-free epoxy coatings, but how much is it, and how to use epoxy coatings, but we don't know much about these, and then we will introduce them to youSolvent-free epoxy coatingsOne.

Two. How epoxy paint is used.
1.First of all, let's talk about the preparation method: we first stir the paint evenly, and there is no precipitation at the bottom of the barrel, but according to the ratio of paint and curing agent 10:
1 ratio, and in winter, when the temperature is low, the ratio is changed to 4:1 blending, and stirring evenly enough and curing for about 15 minutes.
2.Next, the surface treatment requirements: but when the metal surface is painted, the surface must be cleaned first, such as sandblasting, rust removal, etc., and the metal surface should be kept dry after treatment, and the coating can be carried out within 4 hours.
3.Also, the expiration date: but the prepared paint, but in order to achieve the best effect, we recommend that the temperature is about 20 to be used up within another 2 hours, but the remaining unused primer can not be poured back into the original paint, which will pollute the original paint.
4.Finally, the coating method: but it is best to use high-pressure airless spraying, only in this way can the coating be flat, if the area is small, you can choose to paint by hand, and also to ensure that the coating is flat.
However, after the last time, it must be cured naturally until 7 days before it can be used again. However, before use, you must look at the production date and guarantee date, and generally do not use it if it exceeds the expiration date, so as not to have poor effect and be time-consuming and laborious.
When we buy solvent-free epoxy coatings, we don't know how much ** is, and the above article is about solvent-free epoxy coatings** and how to use epoxy coatings.

Anonymous users2024-02-11Dear, hello, e-12 epoxy resin is a commonly used material with a wide range of use scenarios. If you want to apply pure epoxy powder coating to e-12 epoxy resin, you need to consider the following index requirements: 1
Adhesion: The adhesion between the pure epoxy powder coating and the e-12 epoxy resin should be strong enough to ensure that the coating does not peel off or peel off. 2.
Chemical resistance: E-12 epoxy resin usually works in harsh environments such as humidity and acid, so the coating needs to have good chemical resistance to resist the erosion of these environments. 3.
Heat resistance: E-12 epoxy resin usually works in a high-temperature environment, so the coating needs to have sufficient heat resistance to prevent cracking and falling off caused by thermal expansion and contraction. 4.
Color and gloss: The color and gloss of the coating formed by pure epoxy powder coating should meet the customer's requirements. 5.
Coating thickness: The thickness of the coating should be sufficient to achieve the desired performance and appearance. The above indicators are the main factors that need to be considered when applying pure epoxy powder coatings to e-12 epoxy resins.
The specific requirements will vary depending on the application scenario, usage conditions, and customer needs.
Regarding resin defoamers, you can use the epoxy resin defoamer developed by Yuheng Chemical, which is specially tailored for epoxy resin resin, with high compatibility, very low risk of surface defects, and can be used in systems that require transparency, especially for epoxy resin, unsaturated resin and vinyl resin system, which can be used for gelcoat, hand lay-up, jetting, fiber winding, casting, etc., with excellent cost performance, setting a new benchmark in the industry. In the solvent-free or high-viscosity system, the air mixed by mechanical force is often not easy to remove, with special interface properties, which can significantly inhibit the mixing of air in the early stage, reduce the production of bubbles, and help the escape and rupture of bubbles, so as to obtain a uniform and smooth surface, which can prevent shrinkage and porosity, and has an excellent effect on enhancing the gloss of the paint film. It has a good inhibition effect on the bubbles of high viscosity and high film thickness, especially the solvent-free high film thickness epoxy floor coating, suitable for the foam inhibition and deaeration of unsaturated polyester coatings, gelcoat, jetting, pultrusion, RTM, etc., which can reduce the occurrence of cavities and make the molded products have higher strength and flatness.
Generally speaking, the topcoat of floor paint with a thickness of less than the thickness of the paint film is called a thin-painted floor topcoat by spraying, roller coating or brushing. Thin-coated epoxy floor paint is generally suitable for purified cement floors, such as factory buildings, hospitals, pharmaceuticals, warehouses, offices, laboratories, data rooms, basements, etc.
【Introduction to epoxy flat coating flooring】
Epoxy flat-coated flooring is a two-component epoxy resin system, which is cured to form a thin film with a bright appearance, strong and tough, impermeable decorative surface, and easy to clean. Strong adhesion, good adhesion to the substrate; Can carry medium loads. The cost is economical, the viscosity is low, it is easy to construct, seamless dustproof, oil-resistant, easy to clean, and simple and convenient to repair and maintain. >>>More
Brakes should be avoided as much as possible for carts, etc. The epoxy floor itself has strong corrosion resistance, such as the electric welding Fei Vaser as the floor design, which is often mentioned in the maintenance of the beautiful epoxy floor, oil stains, chemicals and other problems, but also affects the appearance and service life. These oil impurities remain on the surface of the floor. >>>More
In this regard, there are strict construction standards, so in this regard, it can be carried out according to the relevant rules and regulations of the country and the construction standards.
