Paint and Surface Coating
Paints, varnishes & coating materials have widespread applications in industries especially in automobile industries. They are used in buildings, electrical & electronic components, infrastructural units, & military warfare’s as anti-corrosion property & aesthetic requirements. Application of paints on metals, wood & cemented materials prolong their service life to very high extend. In order to understand the protection properties & anti-corrosion properties the paints are required to be tested critically to national & international specifications. Accelerated testing to ensure prolonged shelf life has to be carried out on paints & surface coatings. In this direction protection against corrosion test, salts spray test & weather- metric evaluation are very important.To understand application properties of the paints & evaluation of paint films adhesion test, drying time, gloss test, impact test, and resistance to liquid have their own importance. All these facilities are available in our laboratory.
