Title: The Innovative Contributions of Karl Mechera
Introduction
Karl Mechera is a notable inventor based in Muttenz, Switzerland. He has made significant contributions to the field of thermosetting resins and adhesives. With a total of 3 patents to his name, Mechera's work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a process and plant for manufacturing heat-hardenable meltable mixtures. This innovative process produces a heat-hardenable mixture that forms thermosetting resin, such as a reactive hot-melt adhesive. The method involves preparing a first pre-mixture by melting together a heat-hardenable solid resin and liquid resin, along with a flexibilizer, adhesion-promoter, and/or plasticizer. A second pre-mixture is created by mixing a heat-activatable hardener with a thixotropic agent, hardening accelerator, and/or electrical conductivity-imparting additive. The melt is then introduced into an extruding zone, where the pulverulent pre-mixture is mixed with the first pre-mixture at a controlled temperature to avoid air occlusions in the final product.
Another significant patent involves compositions comprising an epoxy resin and mercaptan-containing compounds. These compounds serve as hardeners for epoxy resins and are particularly suitable for adhesive formulations. The cured products exhibit excellent moisture resistance, making them valuable in various applications.
