  • Additive for inhibiting photolytic degradation reactions in aminoplasts
    Patent number: 7368489
    Abstract: The invention relates to a UV additive for aminoplast resins, to a method for producing a UV additive as well as to uses thereof. Said UV additive contains soluble sterically-hindered nitroxyl compounds in an aqueous aminoplast precondensate. A UV additive for aminoplast resins with several application forms is thus obtained.

  • Anti-bacterial additive
    Publication number: 20070167543
    Abstract: The invention relates to an anti-bacterial additive for melamine resins, in particular for melamine-formaldehyde or melamine-urea-formaldehyde resins. The additive has at least one borate salt and a quaternary ammonium compound as the anti-bacterial active ingredients. As a result of the small number of individual constituents, said additive can be easily incorporated into the melamine resin, is extremely compatible with the latter and has an effective, long-lasting anti-bacterial action.
