Paint inspection

Basic introduction

Beitest undertakes coating (coating / coating film), paint (paint film), pigment and related chemical material composition analysis, performance testing, aging test and formula restoration, paint formula analysis, paint composition analysis, paint testing and other testing services .
North Test is guided by the needs and development of paint technology, based on resource integration, technology sharing, and based on performance testing, formula analysis, and new material development. Promote the development of China's paint industry. Beitest paint testing laboratory involves paint composition analysis, paint formula analysis, paint formula analysis, paint testing, etc. The formal third-party testing laboratory can issue globally recognized test reports for product development reference or major e-commerce platforms . Provide you with technical support for your product process improvement, formula upgrade, sales channel expansion, etc.

scope of test

1 Natural lacquer (also known as national lacquer, large lacquer)
There are raw lacquer and cooked lacquer. Sky soil paint film is tough, good durability, acid and heat resistance, good gloss.
2 Oil paints and coatings
(1) Clear oil (common name cooked oil, fish oil). Made from refined dry oil with driers. Commonly used as waterproof or moisture-proof coating, and used to mix original paint and blend paint.
(2) Oily thick paint
(3) Oily blending paint
3 Resin paint
(1) Varnish (resin paint)
(2) Magnetic paint
(3) Lacquer (common name Lac)
(4) Spray paint (nitro paint)
(5) Reconcile lacquer. Blended with dry oils, pigments, solvents and driers.
