Application and analysis of water-based engineering mechanical coatings!

statistics show that China's construction machinery sales and sales, has both surpassed the United States, Japan, Germany, ranked first in the world, self-severity rate of more than 80%.
The 13th Five-Year Plan for China's Paint Industry predicts that by the end of the 13th Five-Year Plan, the total output of the paint industry is expected to grow to about 22 million tons, with environmentally friendly coatings accounting for 57% of the total production of coatings.
estimates, more than 3.7 million tons of oil-based coatings will be replaced by environmentally friendly coatings

.
according to the China Engineering Machinery Industry Association forecast, China's water-based construction machinery coating application scale will continue to grow steadily at an annual rate of 3-5%.
water-based paint as the main force of environmental protection paint will shine.
characteristics of water-based mechanical coatings
water-based mechanical coatings general-purpose products, including water-based epoxy primers and water-based polyurethane finishes.
can also include customized products such as water-based polyurethane varnishes and water-based polyurethane varnishes, depending on the specific needs of some customers, such as higher appearance requirements.
water-resistant epoxy primer has the characteristics of fast dryness, good matching with atomic ash and excellent salt spray resistance.
water-resistant epoxy primer, salt-resistant and spray-resistant properties, the gloss, appearance and weather resistance of the paint have outstanding advantages. Specifically as follows:
In addition, compared with the same type of products on the market, the appearance of water-based polyurethane paint plumpness is good, aging performance in the industry has outstanding advantages, as follows:

Sex epoxy primer , leveling 15min , 80c x 30min , scraping atomic ash , 80c x 30min , pneumatic grinding , blowing ash dust , spraying water-based polyurethane finish paint , leveling 15min , 80c x 30min , cooling the lower parts.
film thickness range of 50 to 60 microns, paint film thickness range of 40 to 50 microns.
image below shows the composition of solvent-based coatings (left) and water-based coatings (right):
can be seen from the figure, water-based coatings VOC content is low, high moisture content. Therefore, the construction and drying performance of water-based coatings are greatly affected by the temperature and humidity of the surrounding environment.
construction environment temperature is recommended at more than 15 degrees C, air humidity must be less than 80%, the temperature is too low, humidity is too high, water-type paint construction is prone to hanging, flash rust and other problems.
