Nordson Series 70 Mixers are designed for high-pressure applications that use two-component materials (adhesives and sealants). In-line mixer housings are made from 304 stainless steel. The spiral elements are made with 316 stainless steel and are NON-REMOVABLE. The elements are permanently joined to the housing by nicobrazing1. Non-removable element mixers can be cleaned for re-use by flushing with solvent after use. Alternatively, the mixer may be cleaned via furnace cleaning - the maximum furnace temperature should not exceed 1250° F (676° C).
