Title: Marcel Aschwanden: Innovator in High-Temperature Adhesive Technologies
Introduction
Marcel Aschwanden is a notable inventor based in Freienbach, Switzerland. He has made significant contributions to the field of adhesive technologies, particularly focusing on high-temperature applications. With a total of 2 patents, Aschwanden's work showcases his innovative approach to solving complex bonding challenges.
Latest Patents
Aschwanden's latest patents include formulations for high-temperature epoxy adhesives. This invention presents an epoxy resin system that is particularly useful as an adhesive for high-temperature applications. The system combines a diglycidyl ether bisphenol epoxy resin at amounts of 30-70% by weight, with 1-10% by weight of an epoxy novolac resin, and 10-30% by weight of a polyurethane toughener. The formulation also includes 1-8% by weight of a hardener and 0.1% by weight of a cure accelerator, which is preferably a latent urea cure accelerator. This combination provides a desirable balance of mechanical strength and elastic modulus. The epoxy novolac resin is characterized by specific features, including a viscosity at 25 degrees C. of less than 3000 mPa-s, an average number of epoxide groups per molecule of more than 2 but less than 3.7, and a molecular weight of less than 750 g/mol.
Another significant patent is the method for bonding using one-component epoxy adhesive mixtures. This invention allows for adhesive bonds to be applied by mixing two adhesives with different properties and dispensing them to form bondlines between substrate pairs. The adhesives are thermally cured and cooled, and varying the mix ratio permits adjustments to the properties of the adhesive mixture. This process is particularly beneficial in manufacturing settings where different adhesive properties are required for various bonding areas.
