Improved coatings which incorporate Trinidad Lake Asphalt (TLA), also known as Trinidad Natural Asphalt or Epure, as a raw material therein. The invention provides improved paints, primers, sealers, epoxies, roofing compounds, sound deadeners, road markings, membranes, and many other coating products. The coatings are environmentally friendly and provide improved characteristics relative to prior art coatings. The coatings are made by combining TLA and at least one other known type of raw material, such as solid carriers (e.g., carbon fibers, etc.), and/or liquid carriers (e.g. water, alcohol, etc.) and/or gaseous carriers (polar gases, non-polar gases, etc.).

L'invention porte sur des revêtements améliorés comprenant l'asphalte de la Trinité (TLA) connu également sous le nom d'asphalte naturel de la Trinité ou Epure et utilisé dans cette invention comme matière première. Ces revêtements améliorés sont des peintures, des amorces, des agents de scellement, des époxy, des matériaux de couverture, des matériaux insonorisants, des marquages routiers, des membranes et bien d'autres produits de revêtement. Ces revêtements sont sans danger pour l'environnement et présentent de meilleures caractéristiques que ceux de la technique antérieure. Pour obtenir ce type de revêtement, on combine l'asphalte de la Trinité et au moins un autre type connu de matière première tel que des supports solides (fibres de carbone, etc.) et/ou des supports liquides (eau, alcool, etc.), et/ou des supports gazeux (gaz polaires, gaz non polaires, etc.).
