EPOMIN\u2122 also has polar group (amino group) and hydrophobic group (ethylene group) in its structure, which and enhances its bonding force with materials of different polarities. These comprehensive bonding forces of EPOMIN\u2122 are utilized in fields such as adhesion, ink, paint, and pressure-sensitive adhesive agents.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">High Cationicity<\/h3>\n\n\n\n<p>EPOMIN\u2122 exists as polycation in water, and it neutralizes and adsorbs all types of anionic materials. EPOMIN\u2122 also chelates heavy metal ions. This highly cationic property of EPOMIN\u2122 is utilized in fields such as paper manufacturing, water treatment, plating bath agents, dispersants, etc.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Highly Reactive<\/h3>\n\n\n\n<p>Because of its reactive primary and secondary amino group, EPOMIN\u2122 easily reacts with epoxy, aldehyde, isocyanate compounds, and acid gases. This highly reactive property of EPOMIN\u2122 is utilized in the modification of epoxy resins, aldehyde adsorbents and dye-fixing agents.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span style=\"text-decoration: underline;\">Improved Adhesion with EPOMIN\u2122 :Application Examples<\/span><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Exhibits Strong Adhesion Derived from Primary Amino Groups<\/strong><\/h4>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-2 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-top is-layout-flow wp-block-column-is-layout-flow\">\n<h5 class=\"wp-block-heading has-text-align-left\">Tape peel test<\/h5>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"311\" src=\"https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_1-1024x311.png\" alt=\"\" class=\"wp-image-17901\" srcset=\"https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_1-1024x311.png 1024w, https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_1-300x91.png 300w, https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_1-768x233.png 768w, https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_1-1536x467.png 1536w, https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_1.png 1905w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"402\" src=\"https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_2-1024x402.jpg\" alt=\"\" class=\"wp-image-17902\" srcset=\"https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_2-1024x402.jpg 1024w, https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_2-300x118.jpg 300w, https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_2-768x302.jpg 768w, https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_2-1536x603.jpg 1536w, https:\/\/www.shokubai.co.jp\/en\/wordpress\/wp-content\/uploads\/2025\/09\/epomin_image_2.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Photo:  <br>Substrate used: OPP film  <br>Coating resin: Acrylic emulsion<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<figure class=\"wp-block-flexible-table-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><th rowspan=\"2\">Substrate<\/th><th rowspan=\"2\">Coating Resin<\/th><th colspan=\"4\">Primer<\/th><\/tr><tr><th>None<\/th><th>SP-200<\/th><th>P-1000<\/th><th>P-3000<\/th><\/tr><tr><th rowspan=\"3\">OPP Film<\/th><th>Solvent-based Acrylic Resin<\/th><td>\u3007<\/td><td>\u3007<\/td><td>\u3007<\/td><td>\u3007<\/td><\/tr><tr><th>Acrylic Emulsion<\/th><td>\u00d7<\/td><td>\u25b3<\/td><td>\u25b3<\/td><td>\u3007<\/td><\/tr><tr><th>PVA Resin<\/th><td>\u00d7<\/td><td>\u3007<\/td><td>\u3007<\/td><td>\u3007<\/td><\/tr><\/tbody><\/table><figcaption>Drying conditions:80\u2103<br>EPOMIN\u2122 was applied as a primer onto the substrate to form a film.
