Epoxy vinyl ester Clinic Beton Iran

Vinyl Ester Resin Coating is one of the most widely used resins in various industries. Epoxy vinyl ester resin can be used to prepare protective and surface coatings, adhesive and filler paste and mortar, and other chemical reactions. If vinyl ester resin is used for filling mortar between aggregates, the prepared product can also be used as waterproof insulation (sealing insulation). Vinyl ester resin has very good chemical properties and is resistant to many substances and chemical environments. The thickness of vinyl ester resin when used is about 20 to 40 mm. One of the most important advantages of vinyl ester resins is its extremely high resistance to acidic materials and environments. This resistance increases by adding glass flake. Vinyl ester resin is also used in water and chemical storage tanks, high temperature equipment coating, concrete coating and water wells. Vinyl ester resin can be combined with quartz minerals, silica, ceramic fillers, which should be designed according to the project specifications, in order to achieve the best mixing plan with the aim of achieving the highest efficiency.

Properties of vinyl ester resin surface coating

The surface covered by vinyl ester resin has extremely high resistance to all kinds of chemicals. Also, its resistance to wear, erosion and damage is unparalleled. Its implementation is relatively easy and can be done simply with the help of manual rollers. Also, if vinyl ester is combined with some epoxies, it can be used as a structure sealing coating. Vinyl ester coating is resistant to various acids such as citric acid, acrylic acid, chromic acid, chloroacetic acid, fatty acids, formic acid, hydrochloric acid, lactic acid, nitric acid, phosphoric acid and sulfuric acid.

Appearance and technical characteristics of vinyl ester coating

The appearance color of this resin is brick gray and red. Its mixing ratio with water is 1 to 4 to 8. Tensile strength, adhesion strength to metals, adhesion strength to concrete are 775, 175, and 25 kg/cm2, respectively. The increase in the length of this resin in different conditions is between 2 and 3 percent. In humid weather up to the maximum temperature of 160 degrees Celsius, it will have favorable conditions and performance. In dry weather up to 200 degrees Celsius, the performance of this resin will be favorable.

The surface on which the vinyl ester resin is to be applied must be free of any dust and oil stains. The surface under the resin should not have colors or materials that are not compatible with vinyl ester and interfere with its work. The surface under the vinyl ester should be completely dry and its temperature should be at least 10 degrees Celsius. After the implementation and operation of installing vinyl ester, the ventilation should be such that the desired surface is completely dry with one hand. Also, vinyl ester resin can cause damage if it comes in contact with skin or eyes for a long time. If this happens, wash it immediately and see a doctor.

About vinyl ester epoxy:

Vinyl esters are reaction products of epoxy resins with ethylenic unsaturated acids. Except for special cases, vinyl ester resins usually have unsaturated ends. This end can perform the cross-linking reaction. It can also polymerize vinyl ester chains or be copolymerized with styrene.

Most conventional vinyl esters are made by esterification of a diepoxide resin with an unsaturated monocarboxylic acid. They can be cured by free radical reaction alone. or dissolve it in a monomer such as styrene and obtain a liquid resin. In this case, vinyl ester can be used like polyester resin.

Vinyl ester resins that Iran Concrete Clinic Chemical Production Company (consulting engineers of Mehrazan Paydar) uses in the production of its products and is also a supplier and importer of Hetron products in Iran. They have much better toughness and chemical resistance than polyester resins. The main chain of vinyl ester-forming epoxy causes higher toughness and increased tensile length.

The molecular weight of vinyl ester resins depends on the type of epoxy used. For this reason, the tensile strength, elongation, softening point and reactivity of the final resin are determined by the molecular weight and initial structure. This makes it possible to design different properties for different applications. Vinyl ester resins have good chemical resistance compared to unsaturated polyesters.

Part of this feature is related to the absence of ester bonds in the epoxy chain. The polymer components are connected by phenyl ester bonds. Compared with ester connections, these connections are more resistant to most chemical environments, especially in strong alkaline conditions. The ester bond is present only at the end of the vinyl ester chain. This minimizes the attacks of chemical agents.

Vinyl ester resins include three families of vinyl ester resins based on bisphenol A, novolac epoxy and brominated epoxy. Novalak-based resins have better thermal and chemical resistance and can be used in these places. According to the chemical structure of these resins, it can be said that these resins have many properties of epoxies, but they are processed like polyesters. Due to the addition of styrene to vinyl ester, it reduces its viscosity and increases its processability. Vinyl ester resins are very tough and chemically resistant

They also have a good attitude. These resins can be used in various processes such as manual layering, filament winding, and pultrusion.

Buy and price vinyl ester epoxy

Making the market is a database and a network of manufacturers and suppliers of construction products that introduces companies and specialized reviews of construction products. The general purpose of building a market is to establish a direct relationship between the buyer and the producer. Dear buyers can refer to the market system for information about anti-acid coatings and purchase silicone waterproofing from reputable sellers.

Manufacturers and suppliers can register in the market construction system and participate in the special sales festival by placing construction products and inserting the suggested price and increase the sale of their products.
