It has unique features that other coating processes do not have, allowing for the extraction of various possibilities such as material performance, quality, and even process improvements.
Please feel free to contact us at i-kaihatsu@nittobogrp.com. "Dot Coating" is a technology that coats functional agents in dot form on various materials. It has the following technical features and will support your company's problem-solving. Technical Features: - Can fix particles in an exposed state on the surface. - Can coat on coarse fabrics. - Can provide high-performance materials. - Can form two layers of dots. - Can coat hot melt and thermoplastic resins in dot form on the substrate. Expected Problems to be Solved: - Want to effectively utilize the functions of additives such as particles and powders. - Want to increase the productivity of the lamination process. - Want to reduce the amount of adhesive used. - Want to bond and laminate without compromising the properties of the substrate (such as sound absorption, stretchability, breathability, flexibility, etc.). - Want to bond different materials. - Want high-performance materials or to impart high functionality (such as windproof, thermal insulation, reinforcement, ultra-thin fabrics, etc.). - Want to expand the application of our own materials (functional powders, high-performance textiles, non-woven fabrics, resins, etc.).

Applications/Examples of results
Two-layer dots: Two layers of dots are used for bonding ultra-thin fabrics. By using a thermosetting resin for the lower layer and hot melt for the upper layer, adhesion can be achieved without the adhesive bleeding through the ultra-thin fabric. (For apparel applications) Improving productivity in the lamination process: If adhesives were originally used for laminating multiple materials, pre-coating those materials with hot melt adhesive dots can reduce the adhesive application process. Additionally, it is solvent-free and environmentally friendly. Adhesion of functional powders: By double dot-coating deodorants, equivalent deodorizing effects can be achieved with a smaller amount of additive compared to mixing.
Detailed information
-
Double Dot Coating A binder is applied in dot form on the substrate, powder is scattered, and after removing the excess, heating and drying are performed to form two layers of dots. Single Dot Coating Thermoplastic resin powder is filled into an engraved roll and transferred onto the substrate, then heated and melted to form dots of thermoplastic resin.
