| Use | There are 14 types of this product. Given a strong red light yellow, the importance is lower than C.I. Pigment Yellow 12, pigment yellow 83, can be made according to user requirements with different specific surface area of the transparent and non-transparent type. Mainly used in industrial packaging printing ink; Can also be used for PVC and rubber products, in the soft PVC migration trend, color strength ratio C.I. Pigment yellow 83 is about 1 times lower, light fastness is 7%(1/3SD); Can also be used for pigment printing paste. |
