Processing Notes
PRIMACOR 4810 can be processed into dispersion systems for adhesive and binder applications. In dispersion form, it is suitable for use with existing coating and bonding processes depending on the final formulation, substrate and equipment conditions.
For processing stability, equipment used for this resin should be constructed with corrosion-resistant materials. Dies and adapters are recommended to be stainless steel, duplex chrome plated or nickel plated.
Final formulation, pH, dispersion conditions, coating weight, drying temperature and bonding performance should be confirmed by customer testing according to the final application.
Compliance and Additives
The technical data sheet identifies PRIMACOR 4810 as an ethylene acrylic acid copolymer adhesive resin for use with metallic, cellulosic, glass and other substrates. Final regulatory suitability should be confirmed according to the customer’s final product structure, application field and local regulatory requirements.
