Eagle Styrene Acrylic 72/ 50

Primary Uses

Paints & Coatings

Serves as a primary binder in interior and exterior water-based paints, delivering excellent film formation, hardness, and scrub resistance.
Improves adhesion to various substrates like drywall, metal, and wood.
Enhances flexibility to resist cracking and chalking under environmental stress.

Construction & Building Materials

Used in acrylic latex caulks, sealants, and joint compounds for excellent seal integrity and flexibility.
Acts as a binder in cementitious tile adhesives, masonry coatings, and patching compounds.
Improves water resistance, adhesion, and workability of cement renders and stucco finishes.

Adhesives & Binders

Incorporated into pressure-sensitive adhesives, enhancing peel and tack strength.
Used in hot-melt and cold-water adhesives for bonding paper, board, textiles, and laminates.
Employed in nonwoven fabric lamination as a binder to control stiffness and handle time.

Paper & Packaging

Serves as a binder in coatings that provide gloss, printability, and water resistance to paper and board.
Used in packaging adhesives for corrugated board lamination and box sealing.

Textiles & Fibers

Acts as a finishing aid for textile treatments to improve hand feel and dimensional stability.
Used in impregnation formulations for fabric reinforcement and coating.

Woodworking & Veneer

Used as a wood primer or sealer, improving adhesion of paints and varnishes.
Employed in laminating adhesives for plywood and particleboard products.

Secondary Uses

Industrial & Decorative Flooring

Used as binder in decorative concrete overlays and thin-set floor toppings.
Serves in maintenance coatings for concrete and sports surfaces.

Arts & Crafts

Available as a binder in art gesso, craft glues, and decorative coatings.
