1. In road marking paint
According to the usage, road marking paint can divided into pavement marking paint and sign paint; according to the construction requirements can be divided into solvent - based paint and hot-melting paint. The hot-melt paint has the characteristics, such as fast drying, no pollution during construction, wear resistance, long service life under pressure, and the surface can be sprinkled with glass beads to increase the identification.
2. In architectural coatings
The development of architectural coatings is inseparable from the development of corresponding raw material, synthetic resin emulsion is the main film-forming material of building coating, which plays a decisive role in the variety performance and grade of coating. Because petroleum resin does not contain polar groups, it has the characteristics of water resistance, acid and alkali resistance and weather resistance.
3. In varnish and blending
The petroleum resin has good solubility in a solvent and can be miscible with most of the resins. the obtained paint has fast drying property, good brushability and leveling property, and has improved gloss of the coating film. Therefore, petroleum resins are often used to mix varnish and other paints.
4. In anti-corrosion coatings
Petroleum resins are widely used in coatings anticorrosion. Such as the preparation of steel plate anti-rust paint, ship primer, silver and aluminum paint. Used for metal corrosion and and a general decoration for silver and aluminum powder.
5. In other coatings
Petroleum resins are also widely used in some special coatings. The Marine Coatings Research Institute of the Ministry of Chemical Industry has developed a fishing gear antifouling coating. This is a surface protection coating applied to the net of the fishing tackle net, which can effectively prevent the attachment of marine life to the fishing gear, and the validity period is up to 6 months.
In the coating industry, petroleum resins can be combined with other resins to replace high-priced resins in whole or in part, thereby reducing costs and improving various properties such as gloss, hardness, water resistance, stability and chemical resistance.
