Overview
The LENETA Form P300-7C transparent hiding power card is a colorless and transparent thin film substrate mainly used for performance testing and observation of coatings. It can be used as a carrier for coating Spreaders to evaluate the Appearance properties of coatings such as Color, Gloss and transparency; it can also be placed on a black and white background to evaluate the hiding power of coatings. In addition, the transparent card can also be used as a cover layer to provide protection after scratch drying without blocking the line of sight for continuous observation.
Features
1. Material Transparent: Colorless transparent film, easy to directly observe the coating Appearance.
2. Multifunctional: It can be used as a Spreader substrate to test Color, Gloss, transparency, and can also be used for hiding power evaluation.
3. Protection function: Can be used as a cover layer to protect the scraped coating sample without affecting visibility.
Specifications are clear: size 194 * 260mm, thickness 175 µm, Encasement 125 sheets/box, easy to use and manage.
Principle
This product is used as a transparent test substrate, and its Working Principle is based on its physical properties. When the coating Spreader is applied to it, its transparency allows rays of light to pass through, making it easy to directly observe and evaluate the Color, Gloss and transparency of the coating. When it is overlaid on a black and white contrast background, it is possible to clearly compare and judge the covering ability of the coating to the substrate due to the difference in background Color. When used as a cover layer, its transparent characteristics make it possible to protect the sample under the coating while still maintaining the visibility of the sample for subsequent inspection or comparison.
Applications
Coating performance test, coating Appearance evaluation, hiding power evaluation, laboratory scratch sample protection
Standards
The data did not mention specific compliance criteria.
Steps
1. As the test substrate: Spreader the paint to be tested evenly on the transparent hiding power card.
2. Appearance properties: Under natural light or Standard light source, directly observe the Color, Gloss and transparency of the coating.
3. Evaluation of hiding power: place the transparent card coated with paint on the black and white background and observe the degree of covering of the background by the coating.
4. As a protective coating: cover this transparent card on the sample after scraping and drying to protect the coating surface.
Notice
• Before use, make sure that the surface of the transparent card is clean and scratch-free, so as not to affect the test results.
• Spreader coating should be as uniform as possible to ensure the accuracy of the evaluation.
• When used for hiding power evaluation, ensure that the black and white background is clean and contrasting.
• When used as a cover, handle it with care to avoid scratching the coating sample below.
• The thickness of the product is 175 µm, please pay attention to its flexibility when operating to avoid damage caused by excessive bending.
• Please use it according to the specification (194 * 260mm), and pay attention to dust and moisture-proof when storing.
