Description
Form BH is a sealed Plain Black Chart with overall dimensions of 11-1/4 x 17-1/4 in (286 x 438 mm).
Its large black background is ideal for observing surface irregularities in clear and light-colored paints. Uses include:
- Open time testing as defined in ASTM D7488-11 Standard Test Method for Open Time of Latex Paints.
- Evaluating dry time with a dry time recorder. The chart can be cut in half and used instead of a glass plate for applying multiple strips of paint simultaneously with a Cube Film Applicator.
- Rating splatter during roller applications. In this test, the roller does not apply paint directly on the chart. Rather, the chart is placed horizontally, below the roller, to collect the splatter.
