Chemical Structure
Introduction
Skinning is the biggest nuisance in protective coatings. Skinning causes the avoidable waste of a costly coating material. Paint containers are not always filled to the brim. So air present in a void reacts with the paint, thereby causing oxidation and polymerization of the coating at the air/paint interface. This results in formation of a solid skin during storage. The lost of paint due to skinning is estimated to be as much as 3 to 5%. This not only worries the consumers but also the manufacturers when it comes to filling of small containers. The minute doze of an effective anti-skinning agent can alleviate the difficulty of skinning.
SiSiB® PB2002 is one of the finest anti-skinning agents. It has proved very effective in preventing the formation of surface skin in the packaged solvent based paint, varnishes and printing inks also.
