ER2074

Epoxy Resin

ER2074 is a flame retardant, thermally conductive, two part potting and encapsulating compound. The flame

retardant technology used is of a ‘clean’ type leading to relatively low toxicity fumes and low smoke emission.

• High thermal conductivity; ideal for heat dissipation within LED applications

• Good environmental protection; water and chemical resistance

• Does not contain abrasive fillers; low wear on dispensing machinery

• Meets UL94 V-0 approval; high level of flame retardancy

Page 3 Bulk Mixing When mixing, care must be taken to avoid the introduction of excessive amounts of air. Automatic mixing equipment is available which will not only mix both the resin and hardener accurately in the correct ratio but do this without introducing air. Containers of Part A (Resin) and Part B (Hardener) should be kept sealed at all times when not in use to prevent the ingress of moisture. Bulk material must be thoroughly mixed before use.
