Improving Cutting and Layering Workability: Fray-Free and Shift-Resistant "Glass Cloth Dot"
Proprietary dot coating transforms the common sense of glass cloth. Suppressing fraying and weave misalignment to achieve both dramatic efficiency in layering processes and high-quality results.
Nittobo’s "Glass Cloth Dot" is an innovative new material featuring a uniform dot-pattern coating of hot-melt resin on the surface of glass cloth. It significantly suppresses "fraying," "weave misalignment," and the generation of "glass fuzz (dust)" during cutting and processing—common challenges with conventional glass cloth. This reduces the burden on operators and contributes to maintaining a clean working environment. The most significant feature is its self-adhesive function via heating. This prevents shifting during the layering process and makes shaping to the mold easier, strongly supporting shorter working times and labor savings. The amount and spacing of the hot-melt material can be optimally adjusted according to the application. This ensures product quality stability and improved impact resistance without compromising resin impregnation. It provides the ideal solution for modern composite molding sites where productivity improvements and advanced quality are required.
