Patent number: 6797789Abstract: This invention relates to the process of preparation and application of a plural component, fast cure phenolic/polyurea elastomer coating co-polymer system. The disclosed coating system is prepared from the reaction of an isocyanate component and an amine terminated resin blend component. Each of the two components may individually or both contain a phenolic resin based product as part of the active hydrogen donation for the reaction with the isocyanate. These phenolic/polyurea co-polymers are characterized as having significantly improved chemical resistance and lower moisture vapor transmission through the coating system over conventional polyurea elastomer coating systems, thus making the coatings suitable for highly corrosive environments.Type: GrantFiled: October 19, 2001Date of Patent: September 28, 2004Assignee: Visuron Technologies, Inc.Inventors: Thomas E.

Patent number: 5962618Abstract: Spray polyurea elastomer systems have improved adhesion to a substrate with the incorporation of a functional alkoxy silane and water. Such systems typically also include a quasi-prepolymer of an isocyanate and an active hydrogen-containing material, and at least one amine resin, and preferably an amine-terminated chain extender. The system may also benefit from the incorporation of a higher than usual proportion of 2,4'-isomer methylene diisocyanate (MDI). The viscosity of the various components, as well as various processing characteristics, may be improved by the addition of an alkylene carbonate. The spray polyurea elastomer systems of this invention also have improved abrasion and impact resistance.Type: GrantFiled: March 17, 1998Date of Patent: October 5, 1999Assignee: Huntsman Petrochemical CorporationInventors: Dudley J.

Patent number: 5962144Abstract: Polyurea elastomer systems have improved adhesion to a substrate with the use of a primer that is applied first. The primer is composed of hydrophobic, primary hydroxyl-containing compound, for example, castor oil, and an isocyanate. It is not necessary to wait for the primer to cure prior to applying of the polyurea elastomer system. The primer system is particularly useful on wet substrates, where the primer penetrates the sub-strate prior to polyurea elastomer spraying. Regardless of whether the substrate is dry or wet, adhesion is improved.Type: GrantFiled: April 3, 1998Date of Patent: October 5, 1999Assignee: Huntsman Petrochemical CorporationInventor: Dudley J.
