Publication number: 20130245183Abstract: The present invention provides a water-based coating system that can be used to form a durable, abrasion resistant, tough, protective coating on a wide range of substrates. The coating system advantageously has excellent adhesion properties and can be directly coated onto stainless steel surfaces without requiring an intervening primer layer. Primer layers or other types of coatings can be used in combination with the coating system of the present invention if desired, however. The coating system is particularly effective for protecting metal-containing substrates such as intermodal, refrigerated cargo containers. The resultant coatings are flexible and impact resistant. Being water-based, the coating compositions have lower VOC emissions and less residual odor than solvent-based compositions.Type: ApplicationFiled: April 16, 2013Publication date: September 19, 2013Applicant: Valspar Sourcing, Inc.Inventors: Channing C. Beaudry, Donald W Boespflug, Wylie H Wetzel, Walter J Blatter, Feng Zhang, T. Howard Killilea

Patent number: 8535478Abstract: The present invention relates to a high-performance silicone elastomer composition that is adhesive and that can be crosslinked at high temperature for the assembly of silicone-based substrates, both by platinum and peroxide catalysis, and that may lend itself to a strip conformation. The composition comprises at least one gum, one catalyst and one adhesion promoter of polyorganohydrogensiloxane type, the nature and the amount of said adhesion promoter having been chosen so that Si—H groups are in excess following the reaction for crosslinking the composition, so as to obtain a potential surface density of covalent Si— bonds with the silicone substrate to be bonded of at least one covalent Si— bond per 60 nm2.Type: GrantFiled: July 30, 2008Date of Patent: September 17, 2013Assignee: Bluestar Silicones France SASInventors: Alain Pouchelon, Francis Lafaysse
