Characteristics and application of acrylic resin coatings;
1, excellent weather resistance. Acrylic acid, a weather-resistant resin recognized at home and abroad, is the main film-forming material, and chlorosulfonated polyethylene rubber with excellent weather resistance and corrosion resistance is the main modifier.
2. The coating has good weather resistance and gloss retention, and good color retention.
3. Excellent corrosion resistance. The coating has excellent chemical resistance, water resistance, alkali resistance, salt resistance, seawater resistance, oil resistance and aging resistance.
4. Strong decoration. The coating is plump, smooth, bright, wear-resistant, easy to decontaminate, impact-resistant, colorful and beautiful.
5, the construction is convenient, and it is cured at room temperature. The coating can be cured at 5 ~ 40℃ or baked at 60 ~ 80℃ for 30 minutes to form a film, and has good adhesion to metal, cement surface, masonry, wood and plastic products.
use
It is suitable for anticorrosion coating of metal and nonmetal surfaces such as automobiles, ships, mechanical equipment, mines, mining, metallurgy, chemicals, furniture, instruments, internal and external walls of buildings, floors, metal products, outdoor advertisements, guardrails, etc.
shopping tips
The key to choose acrylic resin coating is environmental protection. Nowadays, home decoration is very polluted, and harmful substances such as VOC, CAC, benzene, toluene, formaldehyde and heavy metals will cause serious harm to health. Causes diseases such as reproductive system, cardiovascular and cerebrovascular diseases, and respiratory system. Severe cases can lead to leukemia and cancer. Therefore, environmental protection is the first key to choose acrylic coatings. So to see which brand of acrylic resin coating is good, it is necessary to see whether there is a test report from the National Chemical Building Materials Testing Center when buying acrylic resin coating. The lower the index value, the better the environmental protection performance of acrylic resin coating, which will protect the health of family members.
When choosing which brand of acrylic paint is good, we should first look for the 3C logo. In recent years, due to the uneven quality of building materials market, some harmful substances such as benzene and xylene in acrylic resin coatings have seriously exceeded the standard, posing a threat to people's health, and complaints about the quality of decoration building materials are also common. For this reason, the state began to implement compulsory 3C certification for solvent-based wood coatings, porcelain bricks and concrete antifreeze last year, stipulating that the above three types of building materials that have not obtained 3C certification shall not be produced and sold.
Then look at the packaging and production date. When consumers buy acrylic resin coatings, they should carefully check the packaging to see if there is leakage. Due to the volatility of acrylic resin coatings, the packaging of products must be well sealed. If the metal packaging shows signs of corrosion, it means that the sealing performance is not good or the product has been stored for too long, so it should be weighed carefully when buying. The net content indicated on the packaging of acrylic resin coatings produced by regular manufacturers refers to the pure weight of acrylic resin coatings without packaging objects. For example, if the packaging barrel weighs 5 kg and the net packaging content is 20 kg, then the total weight of the weighed acrylic resin coating should be 25 kg.
Choosing which brand of acrylic paint to buy depends on the price. Everyone likes good and cheap goods, but goods have a cost price, and goods below the cost price will inevitably have various hidden dangers. Friendship paint reminds you that acrylic paint is no exception. Before buying acrylic paint, consumers may wish to compare the prices of brand paint and mid-range paint horizontally to understand the market situation. If the price is ultra-low, they should consider it carefully and don't buy it blindly, so as to avoid the poor quality of acrylic paint.
How to use acrylic resin coating
Acrylic resin coating is a one-component self-drying weather-resistant and anti-corrosive coating based on traditional acrylic resin, which is prepared by adding long-life chlorosulfonated polyethylene rubber, weather-resistant pigments and fillers and weather-resistant additives recognized at home and abroad through advanced technology. Primer is type A, intermediate paint is type B, topcoat is type C, varnish is type D, aluminum paint is type E ... The construction process is as follows.
Process:
Clean up the base → bottom waterproof layer → detail additional layer → brush the middle waterproof layer → pave the reinforcement layer → brush the middle waterproof layer → brush the surface waterproof layer → the first water storage test of waterproof layer → construction of protective layer and facing → the second water storage test → project quality acceptance.
1, the surface of the coated object must be free of scale, rust, oil stain, etc.
2. The substrate temperature must be above 3℃ above the dew point. When the substrate temperature is lower than 5℃, the paint film will not cure, which is not suitable for construction.
3. Brush coating, air spraying and roller coating can be used.
4, must be constantly stirring in the process of coating, in order to avoid precipitation.
5. Recommended film thickness: 60-80um.
Conclusion: Through the above introduction, I believe everyone has a certain understanding of acrylic resin coatings, their uses and characteristics. Acrylic resin coating is a new type of coating made of acrylic resin. Compared with traditional coatings, this kind of coating has less pollution and almost no pollution to indoor air. I hope that through the above introduction, we can help you understand the uses and characteristics of acrylic resin coatings.
