Vinyl ester resin coating is one of the most widely used and widely used resins in various industries. Epoxy vinyl ester resin flooring can be used to prepare protective and surface coatings, pastes, mortars, fillers, and other chemical reactions. If vinyl ester resin is used for the filler mortar between the aggregates, the prepared product can also be used as waterproof insulation (sealing insulation). Vinyl ester resin has excellent chemical properties and is resistant to many chemical materials and environments. The thickness of the vinyl ester resin when used is about 20 to 40 mm. One of the most important advantages of vinyl ester resins is their extremely high resistance to acidic materials and environments. This resistance increases with the addition of a glass flake. In high-temperature equipment coatings, concrete coatings, and water wells, vinyl ester resin is also used in water and chemical storage tanks. Vinyl ester resin floors can be combined with quartz minerals, silica, ceramic fillers that must be designed according to the project’s specifications to achieve the best mixing design to achieve maximum efficiency.
Properties of vinyl ester resin coating
The surface, which is coated with vinyl ester resin, has an extremely high resistance to various chemicals. Also, its resistance to abrasion, erosion, and damage is unparalleled. It is relatively easy to implement and can be quickly done with the help of hand rollers. If vinyl ester is combined with some epoxies, it can also be used as a sealing coating structure. Vinyl ester coating is resistant to various acids, including citric acid, acrylic acid, chromic acid, chloroacetic acid, fatty acids, formic acid, hydrochloric acid, lactic acid, nitric acid, phosphoric acid, and sulfuric acid. The most important features of this cover can be considered as follows:
- High resistance to acidic substances
- Waterproof insulation
- High chemical resistance
- Very easy to implement
- Very high tensile strength
- Ability to adhere to different surfaces
- Resistance to erosion and damage
Appearance and technical specifications of vinyl ester resin coating
The appearance of this resin is gray and red brick. Its mixing ratio to water is 1 to 4 to 8. Tensile strength, adhesion resistance to metals, adhesion resistance to the concrete are 775, 175, and 25 kg / cm2, respectively. The increase in the length of this resin in different conditions is between 2 to 3% at most. It will have favorable conditions and performance in humid air up to a maximum temperature of 160 ° C. In dry weather up to 200 ° C, the performance of this resin will be optimal.
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 contain paint or materials that are not compatible with the vinyl ester and interfere with its work. The surface under the vinyl ester must be completely dry. The temperature must be at least 10 ° C. After applying and installing vinyl ester; 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 the skin or eyes for a long time. In the event of such an event, wash it immediately and see a doctor.
About Epoxy Vinyl Ester
Vinyl esters are the product of the reaction of epoxy resins with unsaturated ethylene acids. Except in special cases, vinyl ester resins usually have unsaturated ends. This end can trigger the networking reaction. It can also polymerize vinyl ester chains or copolymer with styrene.
Most conventional vinyl esters are made by esterifying a dioxide resin with an unsaturated monocarboxylic acid. They can be cooked alone by the free radical reaction and or dissolved in a monomer such as a styrene to obtain a liquid resin. In this case, the vinyl ester can be used like polyester resin.
Vinyl ester resins are used by the Our UK Based Resin Flooring Company to produce its products. They have much better toughness and chemical resistance than polyester resins. The main epoxy chain made of vinyl ester creates toughness and increases the tensile length.
The molecular mass of vinyl ester resins depends on the type of epoxy used. Because of this, the tensile strength, elongation, softening point, and reactivity of the final resin are determined by the molecular mass 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. Phenyl ester bonds make the connection of polymer components. These joints are more resistant to most chemical environments than ester joints, especially in highly alkaline conditions. The ester bond is only present 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, Novolak epoxy, and Burmese epoxy. Novalak-based resins have better thermal and chemical resistance and can be used in these places.
Due 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 also have good chemical resistance. These resins can be used in various processes such as manual layering, helical filament, and palletrogen.
