Carbinol Functional Silicon-Based Technologies for Coatings
Traditionally, organo modification of silicones has involved incorporating polyether, alkyl and phenyl groups onto the silicone backbone. For this study, carbinol functionality has been incorporated onto the silicone backbone using a new capability in Dow Corning to functionalize silicone resins/polymers with organic moieties etc. These novel materials will be capable of co-reacting with many organic cure chemistries, resulting in improved compatibility and other performance aspects of the final coating.
This paper describes the initial study of carbinol functional materials where prototype materials were cold blended into standard parquet lacquer formulations. The next stage of the program will investigate chemically reacting the functional groups into the resin. A range of carbinol fluid structures were evaluated in terms of their performance in UV and waterborne parquet-type formulations. The silicone chemistry is described, as well as the relationship between chemical structure and suitability for particular parquet lacquer formulations.
