Arkema LOTADER® 4503 Terpolymer Ethylene - Acrylic Ester - Maleic Anhydride
Categories: Polymer; Adhesive; Thermoplastic; EMAAA Terpolymer

Material Notes: LOTADER 4503 is a random terpolymer of Ethylene, Acrylic Ester and Maleic Anhydride, polymerized by high-pressure autoclave process.

LOTADER 4503 is a versatile adhesive for extrusion lamination, designed as a ready for use resin to be used pure. LOTADER 4503 gives excellent adhesion to plain, primerless OPET films as well as to other plastic films like OPP, CPP and OPA. It also bonds to easier substrates like PE films, alu foil, metallized plastics, paper and board. Typical uses are:

  • Adhesive for extrusion lamination of polar and non polar films and foils, particularly for laminates involving OPET and aluminium.
  • Adhesive for coextrusion coating of LDPE / Tie / EVOH or PA / tie onto OPET or other films.
