描述
PRIMACOR 5980i EAA Resin is a high acrylic acid ethylene acrylic acid copolymer designed for water-based dispersion and coating applications. With very high acrylic acid content, this grade can be dispersed in aqueous alkali or amine systems and is widely used in solution-based coatings, foil primers and lamination adhesive structures.
Unlike standard extrusion coating EAA grades, SK PRIMACOR 5980i EAA Resin is mainly selected when customers need a dispersible EAA resin with excellent adhesion to polar substrates. It bonds well to metallic, cellulosic, glass and other polar materials, making it suitable for paper coating, metal coating, foil priming, flexible packaging and nonwoven binding applications.
This grade also provides low seal initiation temperature, high hot tack, excellent clarity, high gloss, low odor, oil and grease resistance and water hold-out performance. These properties make it useful in packaging structures where adhesion, sealing behavior and surface appearance are important.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original SK PRIMACOR 5980i EAA Resin with quotation support, technical document assistance and global delivery service.

Advantages
PRIMACOR 5980i EAA Resin is different from conventional EAA extrusion coating grades because it is designed for dispersion. Its high acrylic acid content improves polarity and makes it easier to prepare water-based coating systems using suitable alkali or amine neutralization.
For converters and coating manufacturers, this means the resin can be used in applications where solvent-free or water-based coating systems are preferred. It helps improve adhesion to paper, foil, metal and other polar substrates while maintaining heat sealability and packaging performance.
Compared with standard polyethylene materials, EAA provides stronger interfacial adhesion and better compatibility with polar surfaces. This makes PRIMACOR 5980i especially valuable in foil priming, paper coating and multilayer packaging structures.

Processing Recommendations
PRIMACOR 5980i EAA Resin is typically used for aqueous dispersions, coatings, primers and adhesive systems. Its high acrylic acid content allows dispersion in water-based alkali or amine systems. Processing conditions should be optimized according to dispersion method, neutralizing agent, coating solids, substrate type and final performance requirements.
For foil priming, paper coating or lamination adhesive applications, users should validate adhesion, sealing strength, coating weight and drying conditions under actual production conditions.
