Elastuff® 120 Coating


Description

Elastuff 120 Coating is a 100% solids ASTM Type V Butyl-polyurethane elastomer in a high-build, consistency. Elastuff 120 Coating is a two-component, 1:1 ratio material. Part A component contains the isocyanate. Part B component contains the curative solution.

This system provides a limited workable pot life, and therefore does not require specialized application equipment. Elastuff 120 Coating can be applied by trowel or can be thinned slightly to create a brush/roller-grade version for use on vertical and horizontal applications requiring either heavy or light film builds. Elastuff 120 Coating is a thermosetting polymer coating, which yields a dense, slick finish. The non-porous nature and excellent hydrolytic stability, coupled with resistance to cathodic disbondment, make Elastuff 120 Coating an excellent barrier to moisture and corrosion.

Designed to protect surfaces subjected to abrasion under immersion or wet environments, Elastuff 120 Coating can be used in potable water systems, salt water, various slurry systems, and numerous acid and base solutions.

The high tensile strength of Elastuff 120 Coating contributes to its resistance to abrasion and tearing. This toughness, combined with its high elongation properties, results in outstanding flexibility and impact resistance.

Basic Uses and Advantages

Elastuff® 120 Coating is used as a sealant, caulk, filler, bonding agent and finish where hydrophobic, abrasion and chemical resistance properties are required. It is used over sealed concrete and primed metal surfaces, and also has excellent adhesion to high density polyethylene (HDPE) products when applied in conjunction with a heat treated surface. Typical applications utilizing Elastuff® 120 Coating include interior tank lining, waste/water containment, manhole repairs, flumes, reservoirs, valves, interior pipe, and other areas subjected to aqueous environments.

Elastuff® 120 Coating is a non-toxic lining and can also be used in applications associated with potable water containment. It has been tested and classified by UL in accordance with ANSI/NSF 61, Section 5, Barrier Materials. Any primers or topcoats use in potable water applications should also be certified.
