Introduction
PRIMACOR™ 5980ICopolymer is an ethylene acrylic acid copolymer with excellent adhesion to metallic, cellulosic, glass and other substrates.In dispersion form, it can be used effectively as a foil primer or laminating adhesive for polyethylene and metallized substrates.
PRIMACOR™ 5980I Copolymer exhibits:
· Dispersible in aqueous amines and alkali
· “Clean” dispersion requires no salts, surfactants or solvents
· Dispersions use existing waterbourne application equipment
· Low heat seal temperature, high hot tack
· High gloss, excellent clarity
· Excellent grease and oil resistance, water hold-out and excellent product resistance for flexible packaging applications
· Low odor

Application
Ethylene and acrylic acid (EAA) copolymer resins offer excellent adhesion to polar substrates without the need for primers. Applications include liquid aseptic, dry-food and laminated tube container packaging, and cable shielding.

Extrusion Notes
Equipment used to process this resin should be constructed of corrosion resistant materials. Dies and adapters are
recommended to be stainless and/or duplex chrome or nickel plated.
Notes
These are typical values and are not be construed as specifications. The physical properties are highly dependent on the
manufacturing conditions. So customers should confirm performances by their own tests.
