GILSONITE POWDER SOLUBILITY

GILSONITE POWDER SOLUBILITY

GILSONITE POWDER SOLUBILITY – Gilsonite powder is willingly soluble without heating in aromatic solvents like Benzene, Toluene, Xylene and in most chlorinated solvents. It is also soluble without heating in aliphatic and low aromatic solvents (VM&P and other Naphtha, Ink Oils and Mineral Spirits), but mixing time is longer. Without heating, the pulverized grade is recommended.

 In paint usages, Gilsonite is generally exerted in combination with bitumen (asphalt). Usually, if Gilsonite is used alone, the ultimate paint will be so hard and brittle after drying. In the other had if normal straight-run bitumen is used alone, the final paint is too soft and tacky. So, a mixture of Gilsonite and bitumen is the best to get the sought hardness (penetration) and drying time of the finished paint. In addition to imparting hardness to the paint

 Gilsonite is also increasing the paint’s:

  • adhesion
  • gloss
  • chemical resistance
  • water resistance

 For hardness, Gilsonite has a zero penetration (at 25°C; 100 gm. 5 sec.) compared to the 60-70 pen, 80-100 pen or softer bitumen commonly available from petroleum companies or asphalt manufacturers.
