Latest Patents
Bergmann's latest patents include groundbreaking advancements in single-component sealing substances and polysulfide sheeting. The first patent details single-component sealing compositions based on mercapto-terminated polymers and/or oligomers, which utilize latent hardeners that are substantially water-free. These hardeners are specifically alkali perborate monohydrates, providing enhanced performance in various applications.
The second patent introduces a novel method for preparing polysulfide sheeting. This process involves mixing a curable polysulfide oligomer or polymer with carbon black and manganese dioxide as a hardening catalyst. The resulting sheeting exhibits exceptional short-term heat resistance, maintaining watertightness even when coated with hot-laid asphalt at temperatures of 240 degrees Celsius. Additionally, it offers superior resistance to ultraviolet light compared to conventional polysulfide sheeting, along with excellent penetration and compression set resistance. This sheeting can be laminated to a reinforcing layer and used to create continuous waterproofing layers for bridges, roofs, and other structures.
