Deuteron® MM 677

Aqueous preparation of polymethylurea. Acts as a matting agent. When producing clear varnish, only a small rate of shear is required to incorporate DEU-TERON MM 677. This prevents forming of micro foam in the production batch. Even when DEUTERON MM 677 is added to the mill base or the dispersion-medium, overmilling is practically impossible due to its excellent shear stability. Resulting from its favorable flow properties it is also suitable for post matting of produced aqueous batches, when it is required to adjust the exact degree of gloss. The matting liquid is kept free of wetting agent and binder. Their presence usually limits the compatibility. Waxes or similar products are not included either. Causes little cloudiness and is therefore also suitable for the use in clear varnishes. Does not spoil the recoatability. Has very good light fastness, weather and mechanical resistance. Used in wood glazings, wood- and furniture lacquers, printing inks as well as industrial finishes (air-drying and stoving enamels). In combination with suitable binders the use of DEU-TERON MM 677 allows for the production of weather resistant flat coatings for exterior applications. Can be used in many applications such as repairs, refinishings or the development of multi-coat systems. Dosage: Depending on the required degree of gloss the dosage can be increased up to 25 %.
