Is epoxy paint eco friendly? The difference between epoxy paint and ordinary paint

After the epoxy paint is completely dried, it has no smell and is safe and environmentally friendly. If there is still a smell, it means that the paint film has not dried thoroughly, and the thinner material has not volatilized clean, which is still harmful to the body, so it is recommended to choose a place with good ventilation conditions during construction, and take corresponding labor protection measures. Qirui brand epoxy paint quality, reputation, service AAA level!

The main varieties of epoxy paints are two-component paints, which consist of epoxy resin and hardener. There are also some one-component self-drying varieties, but their performance is somewhat different from that of two-component coatings. The main advantage of epoxy paint is that it has strong adhesion to inorganic materials such as cement and metal; The paint itself is very corrosion-resistant; Excellent mechanical properties, wear resistance, impact resistance; It can be made into solvent-free or high-solids coatings; Resistant to organic solvents, heat, and water; The coating film is non-toxic.

The disadvantage is that the weather resistance is not good, and there is a possibility of chalking after being exposed to sunlight for a long time, so it can only be used for primer or internal paint; The decoration is poor, and the luster is not easy to maintain; The requirements for the construction environment are high, and the curing of the coating film is slow at low temperature, and the effect is not good; Many varieties require high-temperature curing, and the investment in coating equipment is large. Epoxy resin coatings are mainly used in floor coating, automotive primers, metal anti-corrosion, chemical anti-corrosion, etc.

Epoxy paint is composed of epoxy resin, physique pigment and curing agent. It is suitable for painting the inner wall of oil tanks, and can be widely used on the surface of various light metal and cement structures indoors and outdoors, and can be coated in railway bridges, high-voltage transmission towers, containers, offshore drilling and oil production equipment, various vehicle chassis, heavy machinery, ships, chemicals, equipment and pipelines, and gas engineering gas storage cabinets used in different environments.

Epoxy paint has excellent adhesion and can adhere to the smooth surface of light metals such as stainless steel and galvanized sheet without falling off; It has good alkali resistance, and can be used as an anti-alkali primer for concrete and walls, and can also be used as an anti-corrosion topcoat under indoor alkaline corrosion. The paint film is tough, impact resistant, wear-resistant, toughness and bending resistance; And it can be used with a variety of topcoats, which is really easy to use.

Although when it comes to itEpoxy coatingsThe vast majority of people have never even heard of it, but it is widely used in our lives, such as supermarkets, parking lots and other floors are used in epoxy coatings, so what is epoxy coatings? How to apply epoxy coating? Below we will answer them one by one, I hope it will be helpful to you.

What is Epoxy Paint?

Epoxy coatings are composed of epoxy resins, physique pigments and curing agents. It is suitable for painting the inner wall of oil tanks, and can be widely used on the surface of various light metal and cement structures indoors and outdoors, and can be coated in railway bridges, high-voltage transmission towers, containers, offshore drilling and oil production equipment, various vehicle chassis, heavy machinery, ships, chemicals, equipment and pipelines, and gas engineering gas storage cabinets used in different environments.

How is epoxy paint applied?

1. Preparation method: first stir the paint thoroughly until there is no deposit at the bottom of the barrel, and according to the ratio of paint and curing agent 10:1 (weight ratio) special curing agent (when the temperature is lower than 10 in winter, according to the ratio of coating and curing agent 4:

1 (weight ratio) add winter curing agent), stir well and cook evenly for 10 15 minutes before use. It is best to do a curing test first.

2. Surface treatment requirements: when coating the metal surface, sandblasting, shot blasting and rust removal reach the international level, carry out the necessary cleaning after degreasing, keep the surface dry, and paint within 4 hours, when the concrete is painted, it must be air-dried to 10% moisture before painting, and the surface is cleaned.

3. Service life: It is recommended to use up the prepared paint within about 2 hours (20), and do not pour the unused primer back into the original paint.

4. Coating thickness: high-pressure airless spraying, air spraying, the thickness of the dry film is about 60 m, and the thickness of the dry film is 55 m.

5. Theoretical consumption: If you do not consider the influence of factors such as the coating environment, coating method, coating technology, surface condition and structure, shape, and surface area during the actual construction, the general consumption of primer is about.

6. Suggestions for coating methods: In order to make the coating smooth, it is best to use high-pressure airless spraying, and only choose air-spraying under the condition of no high-pressure airless spraying, and manual painting is selected as the third coating method.

7. Dosage of diluent: If the paint is indeed too thick, a special diluent can be added appropriately, and the dosage is 3 10%.

8. Tool cleaning: It can be cleaned with special thinner. If the ambient temperature is lower than 10, it should be extended appropriately.

9. After the last topcoat is finished, it must be cured naturally for 7 days before it can be put into use.

That's all for you: What is an epoxy coating? How to construct epoxy coating and slippery materials? All of it.

1. Film formation. Epoxy paint on the market is a two-component paint, and the film-forming characteristics are characterized by the cross-linking reaction between the epoxy resin and the curing agent, which is an irreversible film-forming characteristic.

In ordinary paints, nitro paint belongs to the physical drying type, and alkyd paint belongs to the oxidative polymerization form.

2. Performance differences.

Epoxy paint has outstanding adhesion to metal (steel, aluminum, stainless steel, etc.), concrete grinding Qingyun, wood and other substrates, and also has a certain adhesion to wet surfaces.

Nitro paints are commonly used on wood, and alkyd paints are more suitable for steel rust prevention with low surface treatment.

3. Chemical properties.

Epoxy paint has strong corrosion resistance, acid and alkali resistance, various solvents, salt water, etc., and the paint film is intact and poor. It can be used for the interior painting of oil tanks and hydraulic equipment.

Nitro paints and alkyd paints have relatively poor solvent resistance. Gasoline can be easily wiped off.

4. Mechanical properties.

The paint film of epoxy paint is tough, wear-resistant, and has strong impact resistance, toughness and bending resistance. It is suitable for coating mining machinery and engineering facilities that are often rubbed, impacted, and stone-hit.

The nitro paint film is thin and needs to be coated through multiple coatings to achieve a better decorative effect.

The hardness of the paint film of alkyd paint is very poor, and the wear resistance and impact resistance are not strong.

5. Moisture resistance.

Epoxy paint has the performance of resistance to damp heat and humidity, and is suitable for use in paint coating in humid air, underwater, sewage and other environments.

6. Weather resistance.

The weather resistance of epoxy paint is relatively poor, and it is not suitable for outdoor use, otherwise it is easy to chalize.

Alkyd enamel and nitro paint have ordinary weather resistance, and the service life in the outdoors is 2-3 years.

7. Supporting performance.

The primer varieties of epoxy paint can be matched with mainstream high-end topcoat varieties such as chlorinated rubber paint, acrylic polyurethane paint, fluorocarbon paint, etc., and then play a better protective role for blind beams, with an anti-corrosion life of up to 5-10 years.

Alkyd paint, nitro paint, etc. are not matched or unsuitable.

8. Paint cost (excluding construction, surface treatment and other expenses).

The market for epoxy paint is about 20-30 yuan a kilogram.

The ** of alkyd paint and nitro paint is relatively cheap, and alkyd paint is about 10 a kilogram.

Summary. Epoxy primer: strong adhesion, anti-corrosion and anti-rust, used for steel, carbon steel substrates;

Is epoxy primer an industrial paint.

Pro, epoxy primer is the <> of industrial paint

Epoxy primer: strong adhesion, anti-corrosion and anti-rust, used for steel, carbon steel substrates;
