Leneta Form M12-BG Black Gray Opacity Chart 25x25mm

Form M12-BG

Lame plating card

Leneta Form M12-BG covering power papers are black and white/gray grid covering power papers, with self-adhesive on the back, and the four models correspond to different colors and sizes. Leneta Hiding Power Paper is imported from the United States and is specially used for testing the hiding power of paints and inks. It does not contain any fluorescent whitening agent and has good penetration resistance, which can well meet the needs of users for hiding power testing.

Seven advantages of leneta covering power paper

The choice of hiding power test paper is related to the coating process

Different paint formulations. Test cardboards are required to have different solvent resistance, stronger or weaker. Different types of resins need to use poor solvents. The polarity of the solvent determines that its organic components can be activated more or less. In response to this problem, leneta provides two types of test cardboard for testing hiding power: cardboard with varnish and no varnish.

Features

1. A test card with a varnish layer, which is very satisfactory for many coating systems: water-based and solvent-based coatings.

2. Ensure that no fluorescent agent is added, in line with ASTMD344 standard

3. Different batches of high color repeatability

4. The characteristics of adhesion, especially suitable for latex paint

5. Sturdy design. Can prevent warping and bending after coating

6. The box is packed with low-permeability shrink film. Protect from moisture during transportation and storage

7. The batch number is printed on each card

Penetration Jam: Used to evaluate the consistency of color and gloss on voided surfaces

Visual assessment of hiding power:

——Comparison/coverage jam

——Black and white grid/coverage rate jam

Brush card stock for informal painting

Special test charts for sag and leveling tests.

Coverage jams with varnish

Has very good resistance to solvents

Very good repeatability of color and gloss from batch to batch

Smooth surface without any texture

Super strong adhesion and extensibility, no deformation and no curling even when exposed to high humidity

Coating spread/hiding power measurement

The basic considerations for the sale of architectural coatings are hiding power and yield, namely

How many coats are required for a complete film?

how many buckets of paint are needed

Hiding power is a measurement of hiding power, also known as spreading rate.

Hiding power (%) = Y black/Y white *100 (%)

100% is complete coverage, i.e. there is no difference in the applied film between the black and white areas.
