|Warning : Flammable Liquid and Vapor
Keep away from heat, sparks and flame. Vapors may cause flash fire. Do not breathe vapors or spray mist. Avoid contact with eyes, skin and clothing. Use with adequate ventilation during mixing and application, Wear an appropriate properly fitted organic vapor cartridge-type respirator (NIOSH approved) during and after application unless air monitoring demonstrates vapor/mist levels are below applicable limits. Follow respirator manufacturer’s directions for respirator use. Wash thoroughly after handling. Wear protective cloves, chemical safety goggle and impervious protective clothing. Use skin cream. In confined spaces it is respirator (NIOSH approved). Use explosion-proof lights and electrical equipment. Use only non-sparking tools and equipment. Wear conductive and non-sparking footwear. Make certain all safety precautions and follow procedures described in OSHA regulations.

|Mixing & Application|
Mixing ratio is 1 part base and 1 part activator by volume. Base component has a thixotropic (gel-like) consistency and will become fluidized upon mixing. Mix base component separately to reduce viscosity and then combine activator component with base component in proper ratio and power mixer.
For immersion or underground service:
Important: Exposure to high humidity, moisture condensation, or strong sunlight during cure time may cause formation of surface haze or blush. Before re-coating, remove this by wiping down surface with Dampney 124 thinner.
|Apply only after through mixing. Thinning will result in reduced film thickness. During cool weather, if thinning is required to establish proper spray pattern, or to improve leveling or flow out for brush or roller application, use up to one pint maximum of Dampney 124 thinner per gallon of coating.
Roller: Use only chemical resistant mohair-type roller. Do not use plastic-type roller. Keep roller thoroughly saturated to obtain maximum film thickness. Do not squeegee coating or apply excessive pressure to roller.
Brush: Use only pure bristle brushes. Apply in sweeping strokes. Do not brush out to a thin line. Do not attempt to remove brush marks.

EPODUR 776 High Temperature Pipeline Coating
A modified epoxy coating for use on buried pipelines that will see elevated temperatures. It is a liquid coating system that can be sprayed applied using airless spray equipment in the field or shop. It is formulated to withstand buried soil conditions at elevated temperatures as well as to with-stand applied cathodic protection voltage encountered in actual conditions.
Epodur 776 protects steel surfaces subjected to immersion in fresh or salt water, exposure in tidal or splash zones, or buried in soil. This coating is recommended for long-term protection against corrosion under extreme conditions.
