Definition of Foam and Defoamer

Foam can be defined as dispersing of gas in liquid. It can be generated during production of coating (grinding, mixing and filling), during application (brushing, rolling and low pressure spraying), or when application of coat in porous substrate like wood surface. To solve this problem, the producer of coating can use defoamers as an additive.


Orientation Agent

Orientation agent is needed on metallic coating, because it is difficult to ensure metallic pigments are eventually distributed in dry thin film. Touch OTAL 2000 series is recommended as a good orientation agent that base compound is Ethylene Vinyl Acetate.

Optical Brightening Agent

Optical brightening agent is additives that give brighten color appearance or mask yellowing the coating. Optical brightening agent that we recommended is from Lambson with brand Photine.
