Latest Patents

One of Henkel's latest patents is a method for generating thin layers on a silicon base. This invention provides a technique for creating high-purity, thermally stable, and dielectric property-enhanced thin layers. The process involves photochemically polymerizing and/or cross-linking non-functionalized organosiloxanes with alkyl groups using pulsed laser radiation. The parameters of this method include a wavelength of less than 400 nm, pulse durations ranging from 10 ps to 1 ms, and energy densities of at least 1 J/cm². These layers are particularly useful as passivating and insulating layers for semiconductor components and circuits.

Another notable patent focuses on electric insulation with a polyolefin base for medium and high voltage applications, starting from about 10 kV. This invention aims to prevent the formation of water trees while minimizing dielectric losses. The process involves adding silicic acid, which is prepared by melting SiO₂-containing mineral substances with various additives to form a homogeneous glass phase. The resulting porous SiO₂ bodies are well-suited for use in cables and wires, enhancing their performance and reliability.
