Latest Patents

One of Berndt's latest patents is titled "Heat cross linkable polyurethane coating compositions." This invention addresses the need for solvent-free or very low solvent coating compositions that are suitable for flexible sheet form substrates, especially textiles. The composition includes a urethane group-containing prepolymer with OH or CONH₂ terminal groups, mixed with a urea or melamine formaldehyde resin and a stable aqueous polymer dispersion or solution. The coating can be applied using direct or reverse coating techniques.

Another significant patent by Berndt relates to "Coating compositions." This invention focuses on compositions that are crosslinkable by heating to form polyurethane plastics for coating substrates, particularly textile sheet-form materials. The compositions are designed to be free from organic solvents or contain at most 10% by weight of organic solvent. They consist mainly of linear and/or branched urethane prepolymers with blocked terminal NCO-groups, aqueous dispersions of urethane polymers, and various amines as latent crosslinkers. The crosslinking reaction occurs at elevated temperatures in a coating tunnel after application to the substrate.
