Need Datasheets?
Click Here to visit our Datasheet Server (TDS, SDS, Fact Sheets, Selector Guides, etc)Permabond Initiator 43 is used in conjunction with Permabond TA (structural acrylic) adhesives as a nomix resin and initiator system. Its solvent free formulation allows a long open time if required. Alternatively, parts can be bonded immediately after application (no need to wait for evaporation).
