Brushout Cards

Designed for informal brushout applications, the paper stock is almost twice the thickness of regular chart paper to give greater rigidity for more convenient handling - nominal thickness: 0.5 mm (20 mils)

Brushout Cards are also used widely for drawdowns and colorimetric measurements.

Checkerboard Charts

One of the earliest hiding power test surfaces was linoleum with a black and white checkerboard pattern. This was soon replaced by sealed paperboard charts of which Forms 10H and 10H-BG Spreading Rate Charts are typical examples. Designed for brushout tests at specified spreading rates such as in ASTM Method D 344 and Canadian1-GP-71, they are also used for drawdown applications like their smaller counterparts Forms 10A and 10B. Black and gray squares in Form 10H-BG provide reduced contrast for testing coatings with lower hiding power.

Opacity Charts

The term "Opacity Chart" refers to charts on which the test pattern is a simple combination of black and white areas, large enough for wide aperture reflectance instruments, as well as for visual opacity and color observations.

Penopac Charts

These combine the test areas and functions of a PENetration and an OPACity chart. They can be considered as universal test charts for research, development and quality control. The choices offered in size and design are responsive to individual laboratory needs and preferences. Form 19BR includes an un-lacquered black area, but is otherwise equivalent in functionality.

Scrub Test Panels - Plastic-Vinyl Chloride / Acetate Copolymer

In a typical scrub test, the coating is applied to the Leneta Scrub Test Panel at a specified film thickness, allowed to dry, then subjected to scrubbing with a straight-line scrub tester.

In ASTM D2486, a 10mil shim is inserted under the panel to accelerate failure and thereby reduce testing time. The scrub resistance is the number of scrub cycles required to remove the coating to a specified end point. Alternatively, the loss in weight is determined after a specified number of scrub cycles as a measure of scrub resistance, with calculation of equivalent loss in film thickness.

Used in ASTM D2486, ASTM D4213, ISO 11918 and Other Scrub Test Methods.

Fig. 1 and Fig. 2 show actual tests of latex flat paints. Note the films have worn down to a feather edge, with no sign of adhesion failure.

Form P121-10N Fig 1. Typical failure using shim per ASTM D2486 Method A Fig 2. Typical failure without shim.

Spray Monitors - Self Adhesive Hiding Power Labels

These are pressure sensitive labels with a hiding power test pattern and a sealed, solvent-resistant surface. They are used primarily with metal panels on which the uniform surface provides no visual clue as to the thickness of an applied paint film.

When placed on such a surface the Monitor presents a contrasting feature by which to observe the hiding during spray application, thereby facilitating film thickness control. It adheres firmly whether air-dried or baked, to present a permanent visual record of film opacity.

Available in Black/ White, Grey/ White and also Red/Grey (not shown).

Spray Strips - Hiding Power for OEM Coatings

These are used by industrial coatings laboratories, principally those involved with the automotive industry, to measure the hiding power of spraying enamels. The chart is attached to a steel panel and the test coating sprayed to produce a "wedge" varying from thin at one end to thick at the other.

After drying, a location on the chart of adequate visual hiding or 0.98 contrast ratio is determined, and the film thickness measured electronically on the steel panel adjacent to that location. Conversely, a location of specified thickness is determined on the steel panel and the contrast ratio measured adjacent to that location.

Available in Black/ White, Grey/ White and, for the S71, Red/Grey
