Hiding Power Charts
These black and white charts are available in the a variety of sizes and patterns to meet the requirements of most popular tests such as hiding power, contrast ratio, colour etc. of paints, Inks, varnish and similar coating materials.
They are constructed of high quality paper based card, sealed and UV cured with solvent resistant lacquer, they are suitable for use with the majority of coating materials.
The uncoated versions are recommended where coatings of paints, varnishes, stains and sealants etc. are intended for application on porous surfaces, plasterboard, wood, bricks.
Some of the properties that can be determined by applying coatings to the charts, either visually and or by instrumentation include; Gloss, Opacity, Contrast ratios, Colour, Levelling, Sagging.
Determination of Coating Properties
Visual determination can be carried out under suitable lighting conditions (See SHCAC Light Booths) or where a more precise determination is required, suitable measuring instruments are available, Gloss Meters, (On coated charts) Opacity Meters, and colour measuring instruments, Spectromatch and Micromatch instruments.
Method for Applying Coating Materials
The charts should be placed on a firm flat surface, an Impression Bed (See above) or Automatic Film Applicator (See range above) or a suitable glass plate.
Fluid materials can applied to the charts by the use of Bar Applicators, Wire-Bars, (See above) brushes, rollers and spray gun/can, (Own supply)
Identification & Traceability
Each individual chart and a cover sheet are identified with the product code and batch number. The top section of the charts have a printed legend for recording sample data; batch, date and time, also there is a 5 mm diameter hole positioned at the top for hanging the charts.
Charts can be supplied in accordance with your specifications in either the same format but printed in less contrasting colours for testing coatings with lower hiding power, also alternative colours in place of black over white and other patterns. (Minimum batch size 5000 pcs)
ASTM D 2243, (Checking the effects of freeze thaw resistance of water-borne coatings) hiding power, gloss, speckling, agglomeration, Coagulation, or colour change.
ASTM D3022, Colour & strength of pigments.
A choice of three charts consisting of plain black and white areas designated for testing hiding power of coating materials, the areas are of sufficient size for reflectance measurement by instruments.
Opacity & Drawdown Charts
The checkerboard and chevron patterns charts are designed for visual assessment for opacity of coating materials.
Combined chevron pattern with black and white areas offers both visual and measurement by instrumentation for opacity and gloss
Plain White Opacity Charts
These cards are for determination of opacity/covering power of coatings intended for white substrates.
Penetration Charts (Uncoated)
In addition to those shown, other charts within the Sheen range can be supplied uncoated, subject to minimum order of quantity of 5000.
