While epoxy resins first react by polymerizing an alcohol with epichlorohydrin to form a resin which is then cross-linked with various amines to form epoxy groups, the curing processes for polyurethanes, for example, are carried out by reactions between isocyanates and polyols, resulting in a softer and more flexible end product. This comparison can be helpful when selecting materials for specific applications.  <\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-66f1250 elementor-invisible elementor-widget elementor-widget-heading\" data-id=\"66f1250\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;fadeInUp&quot;}\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Conclusion<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-99abda7 elementor-invisible elementor-widget elementor-widget-text-editor\" data-id=\"99abda7\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;_animation&quot;:&quot;fadeInUp&quot;}\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Thanks to its versatile properties, such as high abrasion resistance, strength, chemical resistance and excellent adhesion, epoxy resin offers a wide range of applications in industry and trade.  <\/p>\n<p>However, to achieve the best possible results, the curing process must be precisely controlled.
