Isonel® 31 SA is a solvent based isophthalic modified varnish, which has an excellent long-term tank stability. The cured product gives a tough/resilient film with an excellent chemical and moisture resistance. Isonel® 31 SA has a thermal class of 180°C and exhibits compatibility with most types of insulation products and systems. It is ideally suited for processing of transformers, especially where a clean drain characteristic and fast cure is required as well as the impregnation of small stators and coils where flexibility of connection leads has to be maintained. It is designed for use in applications where also high bond strength and good moisture and chemical resistance is required. Polymerization is initiated by the effect of heat and proceeds as a rapid chain-reaction until a three dimensionally cross linked, duro plastic cured material is produced. The product fulfils the directive 2011/65/UE e 2002/95/CE (RoHS). The raw materials of the product are pre-registered according to directive to CE 1907/2006 and s.m.i. (REACH).
