basic introduction

In order to promote energy conservation and environmental protection, with the approval of the State Council, from February 1, 2015, the consumption tax on coatings with a volatile organic compound (VOC) content greater than 420g/L under construction will be levied.

Paint refers to the general term for a class of liquid or solid materials that can be applied to the surface of an object to form a solid coating with protection, decoration or special properties.

The Chinese coatings industry defines VOC as "any organic compound with an initial boiling point less than or equal to 250 °C at a standard pressure of 101.3 kPa.

Test product range

The coating consists of primary film-forming substances, secondary film-forming substances, etc.

According to the main film-forming substance coatings: oils, natural resins, phenolic resins, asphalts, alkyd resins, amino resins, nitros, filter vinyl resins, vinyl resins, acrylic resins, Polyester resins (aqueous coatings), epoxy resins, polyurethane resins, elemental organics, rubbers, celluloses, other film-forming materials, etc. (Including solvent-based and water-based paint.)

Separate resins, curing agents, thinners and auxiliary film-forming substances in coatings do not need to be tested.
