SILRES IC 368 has been formulated so that an addition of only 15 percent is sufficient to improve the UV and weathering resistance of the organic binder in a coating system – without detracting from its mechanical properties. It is a low-viscosity liquid and can be processed without organic solvents. Cooking equal proportions of alkyd and silicone resins reduces the viscosity by up to a factor of three compared with silicone solid resins. VINNOL H 30/48 M’s solubility in pure ester results in a clear, color-free solution without having to use any ketones. With its higher vinyl acetate content in the polymer backbone, it can already be heat sealed at lower temperatures. It is suited for packaging thermosensitive pharmaceuticals and foodstuffs.
