NSF Approved Hydrophobic Elastomer
ELASTUFF 120 is a two component, 100% solids polyurethane elastomer coating containing no mocha or fillers such as clay or mica. It was designed for protecting surfaces subject to abrasion in aqueous solutions or environments, including water, salt water, various slurry systems, and numerous acid and base solutions. It is equally effective under dry abrasive and/or corrosive environments. ELASTUFF 120 is a highly crosslinked polymer coating, yielding a dense, tight finish. Its nonporous surface and excellent hydrolytic stability make ELASTUFF 120 an excellent barrier to corrosion. The high tensile strength of ELASTUFF 120 contributes to its resistance to abrasion and tearing. This toughness, combined with its elongation properties, also results in outstanding flexibility and impact resistance. ELASTUFF 120 is a solventless system enabling fast, high-build coats without solvent entrapment. It is available in Fast-Cure or Roller-Gradeversions.
ELASTUFF 120 is used over a wide variety of vertical and horizontal primed concrete, steel, iron, wood, fiberglass and polyurethane foam surfaces. Typical applications include interior tank lining, waste/water containment, sewer manholes, flumes, reservoirs, cooling tower basins valves, interior pipe and other areas subjected to aqueous chemical environments. The vertical hold attained by ELASTUFF 120 gives it the ability to uniformly cover coarse or pitted concrete as well as weld seams, bolts, angles and edges, and other irregular surfaces. Film builds from 10 to 250 mils and beyond can be achieved in one coat using multiple pass spray technique. For surfaces exhibiting rough texture or minor spalling, as well as surfaces exposed to seismic activity, settling or other movement, ELASTUFF 120 is available in an expanded version. ELASTUFF 120X3 rises and cures to a thickness approximately 3 times its liquid applied thickness. For applications requiring additional hardness, ELASTUFF 120 is available in a high durometer version, ELASTUFF 125, which has a hardness of 55-65 Shore D at 75'F. |
