Schaetti AG: Hot-melt equipment with flat die
Since many bonded fabrics may not be exposed to elevated temperatures after coating, hot-melt coating is often the preferred method for applying adhesives to the webs. Steatite AG,Switzerland, offers hot-melt equipment with flat film die and engraved roll technology. Besides low exposure of the substrate to high temperatures, the advantages of the process include the fact that it may be used with nonslip adhesives, long-lasting adhesives, self-adhesive coatings and crosslinkable polymers. Hot melts can be applied to almost all substrates, with less adhesive being required in comparison with conventional processes.
