Dr Christoph Thiebes
Senior Manager – Application Development Construction Adhesives & Sealants
Covestro Deutschland AG
Dr Christoph Thiebes studied chemistry at the University of Bonn and the University of Southern California in Los Angeles, where he received his Master of Science degree in 1997. After completion of his Ph.D. thesis in organic synthesis at the Technical University of Aachen, he joined Bayer (now Covestro) in 2001 as a research chemist. After assignments in research, manufacturing and global product management, he took over responsibility for application development in the area of raw materials for construction adhesives and sealants in 2012.
Fast curing means high productivity – Polyurea systems from polyaspartic amines
In a booming construction industry, the need for solutions that provide higher productivity are obvious. Due to their high curing speed, even at low temperatures, 2C polyurea-based sealants and polyurea / polyurethane hybrids are the materials of choice when high productivity systems are needed. They enable fast return to service and an extended working season in the construction industry. Due to their unique combination of performance properties, aliphatic polyurea sealants with light stability, mechanical properties and long pot life are especially favoured. The aliphatic polyurea sealants are based on aliphatic polyisocyanates and polyaspartic amines. This lecture will provide an overview on polyaspartic sealants, optimised formulations and results for formulations with a new polyaspartic amine. In addition, further potential use of such systems in the adhesive and sealants industry will be discussed.
