WACKER: SILRES® IC 368 is a new solvent-free (<0.2%) silicone intermediate that can be chemically bound to an organic binder to form an organosilicon hybrid binder for weather-resistant, low-VOC coatings. When this intermediate is cooked with the same proportion of alkyd and silicone resin, the resultant viscosity is one third of the value obtained with solid silicone resins.
This makes it very useful for combination resins that have an extremely high solids content, yet sufficiently low viscosity, e.g. for low-solvent, high-solids topcoats. This highly versatile new intermediate is suitable for modifying alkyd resins, hydroxy-functional acrylic resins and hydroxy-functional polyesters that are commonly used for the industrial coating of wood and metal, including coil coating.
