What are epoxy paint materials and epoxy paints? Where is the best answer?

 KLC PAINT has an analysis of what epoxy paints are and whatgroups of work epoxy paints use, which answer is good for reference ... Epoxy is an organic compound based on composite resin, with special mechanical properties. It is more resistant to the environment than other plastics. It is the most commonly used plastic in aircraft, ships, and drilling rigs.


1 Overview Epoxy

Epoxy is an organic compound based on composite resin, has special mechanical properties, is more resistant to the environment than other plastics, is the most used plastic in aircraft and ship parts. hydro, drilling rig. The epoxy resin has no ester group so it has excellent adhesion properties and water resistance, and is ideal for use in the shipbuilding industry, as a primary liner and coating for high quality ships instead of polyester. Easily hydrolyzed by water and gelcoat. In addition, because there are two stable benzene rings in the center, the epoxy resin is more resistant to mechanical stress and heat than the straight one. Epoxy is very hard, tough, and heat resistant.

One of the outstanding advantages of Epoxy is its low shrinkage while curing, its adhesion force, and excellent mechanical properties that help the material adhere very well to heterogeneous surfaces such as metals, plastic, concrete, glass, wood ...

1.1 What is the structure of the Epoxy compound?
In essence, monolithic epoxy cannot have such wonderful properties. The whole epoxy needs to be combined with other substances, the same way as rubber.

We know rubber from a few decades ago, today rubber has become indispensable in human development. But the reason why rubber is so widely used is because the effect of sulfur on the raw rubber is so important. At first, raw rubber has a short-chain molecular structure, so it does not have valuable binding properties of polymeric compounds (long-chain form). Sulfur has the effect of bridging raw rubber molecules into long lattice circuits that give vulcanized rubber qualities that raw rubber cannot.

The effect of curing agent on primary epoxy is similar. Primary epoxy has a short-chain molecular structure, so it does not achieve the required properties. The curing agent connects the primary Epoxy molecules to the long mesh-like chains that make the finished epoxy resin have properties that the primary epoxy cannot fully. In terms of chemical nature, Epoxy functional groups cannot connect with each other, so Epoxy must have a participating substance that creates a connection as stable as possible.

1.2 Application of Epoxy compounds?
Now that Epoxy has become popular in the world, Epoxy has created a completely new and much more economical method. Epoxy becomes a film resistant to the mechanics, preserving for all surfaces of materials: cement, iron, wood, plastic ... Epoxy can be used to protect. Epoxy is also excellent in that it can be used with fiberglass, basalt fiber, and carbon fiber to cover places with strong forces such as masts, rudders, wire poles.

Because of these outstanding resistance properties, they are found from Epoxy, so that Epoxy is encased in places subject to both strong and continuous physical, chemical impact. Typical examples are boats, ships with iron shell or aluminum shell, first they are coated with rust-resistant epoxy. After covering the boat's hull with epoxy adhesive, they covered with an epoxy primer, then finished with epoxy-based gloss paints similar to those used in cars, resulting in a boat with a glossy surface like a car. the new car runs ashore and is still resistant to sea water exposure.

The peak of application Epoxy is probably the application in concentrated sulfuric acid (H2SO4) tanks. This concentrated acid solution is corrosive to most metal compounds, some of which are not corrosive are too expensive to store. Epoxy is used to coat the inside surface in contact with concentrated acid of these containers to bring safety and high efficiency savings. However, because of the too high corrosive properties of this acid, people still have to periodically repaint the coating in Epoxy, about every 6 months.

2.1 What is the composition of the Epoxy paint?
As mentioned above about Epoxy compound and its application. Overall, Epoxy is known for its excellent adhesion properties, resistance to heat and chemical effects, excellent mechanical properties and electrical insulation properties. Therefore, it is not surprising that Epoxy quickly is widely used in the coatings industry.

Epoxy paint consists of 2 components A and B, usually mixed in the ratio of 4: 1. Component A is mainly Epoxy mixed with super fine color particles, reinforcing agents, surfactants, solvents, additives ... the purpose is to make the Epoxy color and paintable. Component B is a curing agent as mentioned above, when mixed with component A they create really strong bonds in the network of epoxy molecules.

2.2 Epoxy paint applications Epoxy
paints have fast drying properties, low volatility properties. When the Epoxy paint is painted and cured to create a durable protective coating with excellent hardness, thanks to the added additives that the Epoxy coating has a high gloss, it is easy to clean with water and common tools. .

Epoxy paint is now widely used, used as flooring in factories, garages, basements for garages, hospitals, showrooms ... where there are no materials that can meet the requirements. Special techniques such as Epoxy paint demonstrate as resistance to frictional wear, wash resistance, dust free, mild acid resistance, water resistance and pressure from heavy objects.

2.3 Classification of Epoxy paint

In theory, there are many types of Epoxy paint, depending on the physical properties that people require that Epoxy paint is blended to create those outstanding properties.
Actually on the market today, the most common are 3 types of Epoxy paints:

+ Epoxy paint without solvent.

+ Solvent-based Epoxy paint.

+ Water-based Epoxy paint.
Each of these paint lines has properties and application methods suitable for the actual conditions, but in general, they have the basic criteria of good to very good mechanical and chemical resistance.

III. Characteristics of each Epoxy coating line.
3.1 Solvent-based Epoxy
Paint Oil-solvent (oil-based) Rpoxy paint is an early product when Epoxy paint was newly known in Vietnam. Epoxy oil-based paint period in 2000 must be imported, suppliers also produce very limited by orders and according to the specifications of customers.

Advantages of oil-based Epoxy paint: Hard bottle surface, impact resistant, resistant to corrosion of mild acids ...

Disadvantages of oil-based Epoxy paints:

+ Construction terrain is limited. Do not apply in environments with high humidity or surface.

The construction and usage environment becomes toxic due to the oil containing volatile solvent.

+ Especially, the climate in the North has 4 different seasons, the temperature and humidity of the year change greatly. Improper expansion coefficient leads to cracking, fracture of the paint film surface ...

3.2 Water-based Epoxy coating system.
Water-based epoxy paint was developed, born after oil-based paint. Thanks to modern scientific and technical innovations, water-based Epoxy paint achieves the features of hardened bottle surface, impact resistance, light acid corrosion resistance ... like oil-based paint but improves the weaknesses. points of oil-based Epoxy paint.

Water-based Epoxy paints are water-based, non-toxic, and environmentally friendly. This is an advantage that allows water-based Epoxy paints to gradually replace completely oil-based paints. Water-based Epoxy paint becomes the main floor coating material in areas with high hygienic requirements such as food factories, hospitals, swimming pools ...

Outstanding improvements in water-based Epoxy paints:

Completely chemical reaction occurs during mixing and evaporation. Therefore, water-based Epoxy paints are less problematic than oil-based and have a longer service life.

+ Paint quality is designed to suit the tropical climate of 4 seasons.

Good drying (curing) ability in humid environment. Water-based Epoxy paint expands the construction terrain and conditions much more than oil-based Epoxy paint, such as road tunnel walls, concrete structural items of hydroelectric projects.

+ High safety in construction and friendly with the environment in use.

3.3 Epoxy system without solvents.

Solvent-free epoxy paint, also known as self-leveling epoxy coating. This Epoxy paint does not contain volatile solvents, works on the principle of self-balance, so it is easy to conceal defects on the floor.

When painted, the self-leveling epoxy coating has an average thickness of about 3 mm while that of the water-based and oil-based solvent epoxy has an average thickness of 0.1 mm. Self-leveling Epoxy paint has features relatively superior to the other two lines, the self-flat Epoxy paint line in addition to features such as acid corrosion resistance, antibacterial, waterproof, oil repellent ... Advantages of this paint It has a thick coating, has strong bonding, self-flat epoxy coating is very stress resistant, can allow forklifts under 16 tons to move on the surface under standard conditions.
