EK 580 Rosin Ester Dispersion in Construction Adhesives
Chemical Properties
EK 580 Rosin Ester Dispersion is a unique aqueous solvent-free emulsion with high solids content.
Pressure-sensitive adhesives based on acrylic resin emulsions (acrylates) or styrene-butadiene latex (SBR) that can greatly improve BOPP or initial bond strength, peel strength and maintain lasting bond strength.

Character
1. No alkylphenol polyoxymethylene ether (APEO), no phenol, no acid, no formaldehyde and no solvent.
2. High cohesion, good water resistance and less foam, suitable for high-speed (Min.500m/min) curtain coaters.
3. Compatible with acrylic resins, carboxylate SBR and NR polymers.
4. Higher solids content, less moisture delivery, thus increasing the versatility of the formulation.
5. The base resin has low color/odor and improves anti-aging properties.
6. Excellent mechanical stability, easy cleaning and excellent coating ability.
