Leneta Staining Medium
Article No. 12793
Leneta ST-31 Staining Medium
The Leneta ASTM Staining Mediums are used for washability and stain-porostiy testing of paint and films.
Features
There are two types available:
ST-1 - A finely ground dispersion of high jet carbon black in a blend of mineral oil and odorless mineral spirits. It is specified in ASTM D3450 to meet the laboratory requirement for a reproducible composition of matter, representative in a general way of soilants encountered in the field.
ST-31 - A proprietary composition of pigment and dark colored dye dispersed in an organic liquid vehicle. When applied and then removed from a paint film, the intensity of the resultant stain indicates the degree of film porosity. It is more effective than other media recommended for this purpose.
Manufactured and control tested to assure batch-to-batch uniformity.
Their usefulness extends not only to ASTM tests, but to any soil and stain removal test procedure.
Supplied in 4 fl.oz. (118 mL) cans or jars.
