Description

Pigment yellow 4 (PY4) is an organic compound that is a mixture of calcium pantothenate, cyclic peptide, polycarboxylic acid, glycol ether and hydroxyl group. PY4 can be produced by the reaction of calcium chloride, sodium hydroxide and phenol in a reaction vessel. It has a particle size of 1-20μm and is used as an additive to paints and plastics to increase their resistance to environmental pollution. PY4 also has a functional group that can be polymerized using an initiator such as benzoyl peroxide or AIBN.
