PropertiesWhere VOC is limited, but excellent weatherability characteristics of Gilsonite-based coatings are required, the proper use of chlorinated solvents helps meet VOC regulations without having to accept the limitations of water-borne paints. Gilsonite Low VOC coatings have VOC's of less than 250 grams/liter.
Formulation/Method of ManufactureHeat asphalt and Gilsonite to 350Â°F (175°C), cool, thin with Xylene, then add 1,1,1-Trichlorethane under reflux.
