New Hycar acrylic latex offers excellent resilience.
The nonwoven sample on the left was spray-bonded with a standard acrylic latex; the sample on the right with Hycar 2600X137. The greater resilience of Hycar 2600X137 is demonstrated by its quicker recovery.
Films, binders and adhesives made with our new Hycar 2600X137 latex offer exceptional resilience, lowtemperature flexibility, resistance to heat and light aging. Soft hand, washability, dry cleanability. Good coating holdout. Colloidal stability. Resistance to blocking and foam formation. This versatile acrylic latex can be used for fiberglass and permanent-press finishes. Flock adhesives. Pigment padding and binding. Resin modification. Backcoating. Paper coating and impregnation. Nonwoven binding, textile finishing, and hand building. Hycar 2600X137 contains a heat-activated curing mechanism. If desired, thermosetting resins can be added for tighter cures. Glass transition temperature is -18°C. And note these typical physical properties for a 15-mil film cured 15 minutes at 275°F (140°C). Tensile strength, 500 psi. Elongation, 600%. 300% modulus, 100 psi. Graves Tear, 25 psi. For more information, write B.F.Goodrich Chemical Company, Dept. CN-55,6100 Oak Tree Boulevard, Cleveland, Ohio 44131.
