PRIMACOR 5986
PRIMACOR™ 5986 by SK Chemicals is a ethylene acrylic acid copolymer. It is offered by Chinese suppliers in Jiangsu province. It offers low heat seal temperature, high hot tack, high gloss, very good clarity, grease and oil resistance, water hold-out and product resistance for flexible packaging applications.
Introduction
PRIMACOR™ 5986 Copolymer is an ethylene acrylic acid copolymer with excellent adhesion to metallic, cellulosic, glass and other substrates. It can be used effectively as a foil primer or laminating adhesive for polyethylene and metallized substrates.
PRIMACOR™ 5986 Copolymer exhibits:
· Low heat seal temperature, high hot tack
· High gloss, excellent clarity
· Excellent grease and oil resistance and excellent product resistance for flexible packaging applications

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.
