The main goal of this project is to develop functional thermosetting polymeric adhesives, both solventborne and waterborne suitable for coating on flexible substrates. A significant part of the project is devoted to the development of a waterborne adhesive applicable on waterproof paper substrates targeting to environmentally friendly solutions. The adhesive systems will be developed by formulating thermosetting polymeric materials for achieving coated abrasives through thermal curing. Basic parameters of the formulations to be developed include type and form of the adhesive, curing agent and curing chemistry, curing temperature and pot life. Industrial procedures will be applied for the ultimate testing of the coatings properties. The project is further aiming at gaining an improved insight on the relation of adhesive composition and physicochemical parameters that affect the performance of the abrasive product. Towards the above goal a set of specific measurements will be adopted including thermal techniques, spectroscopic methods and surface characterization technologies to correlate grain topography and adhesive composition with performance.
