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.
