Pigment in Paint Coating Inks Definition Types and
The binder in the paint system plays a key role in terms of determining the pigment and the type of solvent in which it is dissolved. A common choice for a solvent is water as it is compatible with most polymers except some toners. White spirit is a commonly used solvent for long oil alkyd paints which are widely used in decorative gloss paints.

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150250 microns. The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges

Ball mills are used for small batches of difficult to disperse mill-bases. Ball mills are large porcelain lined rotating drums containing golf ball sized porcelain balls. Rolling and tumbling of the balls provides sufficient force to break up agglomerates. Bead mills are used for large batches and can maintain semi-continuous output.

An often used test method is described as follows 7.1 Method A 1. Preparation of a pigment slurry The pigment content is chosen such that after dispersion a non flowable pigment paste is generated. Normally a content of approximately 30 organic pigment and 70 inorganic pigment is necessary to obtain these conditions.
Chat OnlineDriers in Paint All you Need to Know About
Driers are one of the major components of paint. Driers also know as plasticizers are chemically added to the paint as they act as catalysts. The main function of a drier is to accelerate the drying of vehicle (linseed oil) in the paint and in consequence paint film becomes hard. Paint film gets hardened as drier absorbs oxygen from the air
