Los adhesivos de fraguado f\u00edsico son termopl\u00e1sticos, los de fraguado qu\u00edmico forman termoestables, es decir, redes tridimensionales. Otro tipo de clasificaci\u00f3n se refiere al mecanismo de solidificaci\u00f3n. Aqu\u00ed, los adhesivos termofusibles se dividen en pol\u00edmeros amorfos, pol\u00edmeros semicristalinos y pol\u00edmeros de alto peso molecular, los dos primeros tienen una temperatura de transici\u00f3n v\u00edtrea superior a la temperatura ambiente y los \u00faltimos una temperatura de transici\u00f3n v\u00edtrea inferior a la temperatura ambiente. <\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Adhesivos termofusibles Intercol\" width=\"680\" height=\"383\" src=\"https:\/\/www.youtube.com\/embed\/Ypzhe41eUCU?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe>\n<\/div><figcaption>Adhesivos termofusibles Intercol<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">EVA y poliolefina<\/h2>\n\n\n\n<p>Los principales pol\u00edmeros utilizados para el endurecimiento f\u00edsico de los adhesivos termofusibles son resinas de poliamida, poli\u00e9steres saturados, copol\u00edmeros de etileno-acetato de vinilo (EVA), poliolefinas, copol\u00edmeros de bloque (estireno-butadieno-estireno o estireno-isopreno-estireno) y poliamidas. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PSA<\/h2>\n\n\n\n<p>Los adhesivos sensibles a la presi\u00f3n son sistemas de fraguado f\u00edsico que se caracterizan por su pegajosidad permanente. Los adhesivos logran su adhesi\u00f3n a los materiales a unir mediante una presi\u00f3n de contacto a ejercer - al aumentar la presi\u00f3n de contacto se produce una mejor adhesi\u00f3n. Como la uni\u00f3n de adhesivos sensibles a la presi\u00f3n puede tener lugar tanto antes como despu\u00e9s del proceso de fraguado, dependiendo de la fuerza de la pegajosidad permanente, a menudo se utilizan para el prerrevestimiento.
