Application Method:

    MAC-838 can be applied as received, or diluted with one to four parts of deionized or distilled water to meet specific production needs. All previously used release coatings and compound residue should be removed by an appropriate method. McLube Mold Cleaner may be used. A clean surface will assure proper adherence of MAC-838 to the mold surface. MAC-838 should be applied to a heated mold surface, 200ºF (93ºC) or higher, to allow the coating to dry quickly. To assure complete coverage, a second coat is recommended.
