LOTADER® 4503 is a random terpolymer of ethylene, acrylic ester and maleic anhydride, polymerized by high-pressure autoclave process.

Applications
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, primer-less OPET films as well as to other plastic films like OPP, CPP, OPA and reverse-printed films. It also bonds to easier substrates like PE films, aluminium foil, metalized plastics, paper and board.
Typical uses are:
  • Adhesive for extrusion lamination of polar and non-polar films and foils, particularly for OPET and
aluminium.
  • Adhesive for coextrusion coating of LDPE / Tie / EVOH or PA / tie onto OPET or other films.
