SafSil® pumice provides enhanced qualities in interior paints. By proper choice of pumice particle size, the following properties can be improved:
• Burnish resistance
• Flatting
• Abrasion resistance
• Touch-upThe larger particle sizes of SafSil® CT200 contribute most to improving these properties. SafSil® has also demonstrated excellent efficiency replacing natural diatomite in many paints.
- Exterior Paints and Stains
SafSil® is used to formulate exterior paints, primarily to improve the following properties:
- Tint retention
- Frost resistance
- Uses
- Floor Paints - The hardness, chemical resistance, and abrasive qualities of SafSil® pumice make it an ideal candidate for floor and deck coatings. SafSil® can also be used in driveway sealers. The material contributes to rheology and helps film reinforcement. Larger particle size Navajo Brand® pumice grades are used for non-skid floor coatings. Grades such as Grade ½ and Grade 3 have been used successfully.
- Primers and Undercoats - SafSil is used for both architectural and industrial primers. The low soluble salt content of SafSil , as measured by the ASTM D2448 Test Method, imparts improved corrosion properties to maintenance primers. Primers containing SafSil® demonstrate excellent “tooth” for subsequent topcoat adhesion. Even though SafSil® is a relatively hard material, with a Mohs hardness of 5.5-6.0, primers produced with SafSil® exhibit very good sanding qualities.
- Powder Coatings - The coarser CT200 and CT 450 grades work well for gloss control. SafSill® possesses greater Mohs Hardness than the more commonly used fillers in powder coatings. Dosages less than ten percent have increased film hardness and scratch resistance. Although SafSill® is relatively hard, it does not present any equipment wear issues. The exterior performance of SafSill® is well proven. Color and gloss retention are positive attributes of the material.
- Tennis Court Coatings - SafSil® is used successfully in tennis court systems. The material provides film reinforcement, sheen control and outstanding tint retention.
- Traffic Paint - SafSil® is efficacious for traffic paints. The hardness and abrasion resistance of the material makes it ideal for replacing some of the calcium carbonate in most systems. SafSil® can replace diatomite used by some formulators for flatting. Improved performance will occur due the obtaining increased “free binder”.
