Pigments commonly used in powder coatings are as follows: Pigment manufacturers
1. Lightfast yellow G is a monoazo structural pigment yellow, which has good dispersibility and temperature resistance, and its low price also determines its general application in powder coatings, but lightfastness of lightfast yellow G is 6- Class 7, not recommended for outdoor products.
2. Everlasting Yellow GG, also known as Everlasting Yellow 2G, is a green pigment yellow with high tinting strength, high saturation, good solvent resistance and migration resistance, but when the temperature of Everlasting Yellow 2G exceeds 200 degrees Discoloration will occur, so it is not suitable for powder coatings with baking temperatures exceeding 200 degrees.
3. Pigment yellow 83 belongs to red pigment yellow. This pigment is generally divided into three types in China according to its use. One is transparent permanent yellow HR, which is cheap and has poor temperature and light resistance (light resistance 6-7, temperature resistance 180 degrees), mainly used for ink. Product; another kind, translucent permanent yellow HR, which has better temperature and light resistance than transparency (light resistance level 7, temperature resistance 180-190 degrees); Tianjin Zhengzhong Honghua Chemical Co., Ltd. also produces a covering permanent Solid yellow HR02 is more expensive, but has excellent temperature and light resistance, and can be used in outdoor products (light resistance level 7-8, temperature resistance 220 degrees).
4. Pigment red 254, DPP red series, excellent pigment performance, temperature resistance 300 degrees, light resistance level 8, can be used for outdoor powder coatings with relatively high requirements.
