Paint Laboratory

The paint laboratory consists of various equipments that enable us to analyze the liquid paint coating properties, the paint application and film formation in addition to the chemical analysis.
The methods used are those stipulated by ASTM and ISO.

Liquid coating properties:

Coarse particles
Condition in container (skinning)
Viscosity: Ford Viscosity cups
and digital Krebs stormer viscosimeter
Density
Dilution stability
Fineness of grind (Hegman)
Flash point (COC)
pH

Paint application and film formation:

Covering power
Drying time to touch
Hiding power (Pfund cryptometer)
Re-coating properties

Dry coating properties:

Adhesion (Elcometer, cylindrical and conical mandrels)
Aging by light exposure
