Abstract

This project seeks to develop finished polyether silil-based adhesives and sealants for use in industry and civil engineering. This involves an important technological innovation in the science and engineering of polymeric materials, since they have adhesive properties equal to or superior to silicone and polyurethane adhesives in almost all substrates used in industry and civil engineering. Unlike other types of adhesive, they are free from solvents and isocyanates, being, therefore, harmless to the atmosphere and to the health of workers. They also form resistant and quick-setting bonds, which should encourage new production methods in industry and civil engineering. The project will determine the formulations which best suit the needs of the national market for adhesives and sealants. The physico-chemical properties of the formulations obtained will be optimized and compared with silicone and polyurethane based products currently used on the market. At this stage, the basic production processes of the most suitable formulations will be determined and tests carried out in pilot batches using potential customers. Once the product and process parameters have been defined, the intention is to produce and commercialize those products which demonstrate the best costbenefit relationship and market potential. (AU)
