High Temperature Oil: RPL-773ND

Product Description:

RPL773-ND is a PAO and ester synthetic oil formulation for use in high temperature applications involving chains, slides and bearings operating up to 500F (260C) and intermittently up to 600F (315C). It is a clear-amber ashless fluid which will not carbonize or produce hard varnish residue.

RPL-773ND cleans as it lubricates, gradually dissolve pre-existing residues. It is used in electronics processing and manufacturing where it exhibits low volatility and evaporation rates while uniformly coating metal surfaces for a long-lasting smooth surface finish that reduces consumption and extends re-lubrication intervals.

RPL-773ND will assure maximum anti-wear protection and has excellent anti-corrosion and rust protection against water, chemical, lint and dirt contamination environments. It features a cohesive, non-drip additive treatment to resist fling-off onto processing or product materials.

Typical applications include a wide variety of extreme temperature applications, includings chains and sprockets, bearings, conveyors, ovens, slide ways and pulleys found in the textile, electronics, chemical, pharmaceutical, ceramic, plastics, pulp and paper industries
