Determination of conditional viscosity

Standard method:
GOST 8420
This parameter is set by the customer, depending on the type of color coating line, technological equipment and applying technology.

Non-volatile-matter mass fraction

Standard method:
GOST 31939 (ISO 3251:2008)
This Parameter indicates the quantitative content of solid and non-volatile compounds in a colloidal mixture.

Fineness of grind

Standard method:
GOST 31973
The fineness of grind of pigmented PWM influences quality the resulting film, the anticorrosive and decorative properties of coatings.

Density (pycnometric method)

Standard method:
GOST 31992.1 (ISO 2811-1)
This parameter is set by the customer, depending on the type of color coating line, technological equipment and applying technology.

Thickness of a dry film of organic coating on a metal substrate

Standard method:
DIN EN 13523-1
This parameter is set by the customer, depending on the type of color coating line, technological equipment and applying technology.

Gloss of organic coating on a metal substrate

Standard method:
DIN EN 13523-2
Decorative property. This parameter is set at the request of the consumer.

Color difference-Instrumental comparison in the CIElab system

Standard method:
DIN EN 13523-3
The cumulative color difference ΔE between the laboratory colour dyeing and the reference sample of the customer is defined. This parameter characterizes the accuracy of conformity of the batch color shades produced by PWM with the reference sample of the customer.

Pencil hardness

Standard method:
DIN EN 13523-4
This parameter characterizes the resistance of the polymer coating to the deformation that arises during rolling the painted sheet in rolls.

Resistance to rapid deformation (impact test)

Standard method:
DIN EN 13523-5
This parameter characterizes the resistance of the polymer coating to the deformation that arises during rolling the painted sheet in rolls.

Adhesion after indentation (cupping test)

Standard method:
DIN EN 13523-6
This parameter characterizes degree of adhesion (sticking) of PLC to metal.

Resistance to cracking on bending (T-bend test)

Standard method:
DIN EN 13523-7
This parameter characterizes the resistance of the polymer coating to the deformation that arises during rolling the painted sheet in rolls.

Resistance to solvents (rubbing test)

Standard method:
DIN EN 13523-11
It determines the degree of polymerization of the coating by checking resistance of a film to influence of a certain solvent (usually methyl ethyl ketone, MEK),and also testing for wear resistance of the surfaces strength characteristics, coatings, materials and finished products.

Erichsen cupping test

Standard method:
GOST R ISO 20482
This parameter characterizes the resistance of the polymer coating to the deformation that arises during rolling the painted sheet in rolls.
