Latest Patents

One of Isshiki's latest patents is a continuous process for producing reinforced resin laminates. This innovative method involves impregnating a fibrous substrate with a liquid resin that is free of volatile solvents and capable of curing without generating liquid and gaseous byproducts. The process includes laminating multiple resin-impregnated substrates into a unitary member, sandwiching the laminate between covering sheets, and curing it without applying significant pressure. An important improvement in this patent is the adjustment of the final resin content in the impregnated substrate to between 10 to 90% by weight based on the total weight of the substrate.

Another significant patent involves glass fiber-reinforced electrical laminates. This invention comprises a cured assemblage of glass fiber type substrates impregnated with a curable resin composition. The composition includes a halogenated bisphenol type unsaturated polyester resin and an optional halogen-containing epoxy acrylate resin. This laminate is characterized by high dimensional stability, improved through-hole reliability, and excellent mechanical strength. Additionally, a continuous production method for these laminates is described in this patent.
