Houghton Ensis DW 2462 - Dewatering Corrosion Inhibitor

ENSIS® DW 2462 — Premium Dewatering Rust Preventive

ENSIS® DW 2462 is Quaker Houghton's premium dewatering rust preventive — a solvent-based corrosion inhibitor that displaces water from metal surfaces and deposits a thin, waxy protective film providing up to 24 months indoor corrosion protection. Effective on both ferrous and non-ferrous metals, it is the trusted choice for protecting drill pipe, casing, subsea components, steel structures and precision components stored in coastal and offshore environments exposed to salt-laden, high-humidity conditions.

Supplied through Orbit Industrial as an authorised Quaker Houghton distributor. Available in 20L pails. Available by request for quote only — not available for direct checkout.

Product Data Sheet

How ENSIS® DW 2462 Works

ENSIS® DW 2462 is applied to metal surfaces neat — by spray, brush or dip immersion. The dearomatised solvent carrier rapidly displaces water from the metal surface, including from blind holes and crevices, and then evaporates — leaving a thin, dry, waxy protective film that is non-tacky, resistant to peeling and cracking, and effective at neutralising fingerprints. The protective film is easily removed with alkaline or solvent-based cleaners when access to the protected surface is required.

Features & Benefits

Feature	Advantage & Operational Benefit
Up to 24 months indoor corrosion protection	Long-term protection for drill pipe, casing and components stored between drilling campaigns — reducing corrosion-related equipment losses and maintenance costs
Outstanding dewatering properties	Rapidly displaces water from metal surfaces — including from threaded connections, blind holes and crevices where moisture accumulates in coastal storage environments
Thin, dry, non-tacky waxy film	Dry film is pleasant to handle and does not attract dust or contamination — unlike heavier wax or grease-based corrosion preventives
Neutralises fingerprints	Prevents corrosion from accidental bare-hand contact during application, inspection and storage — important for precision components with highly finished surfaces
Effective on ferrous and non-ferrous metals	Protects the full range of metals used in offshore and marine equipment — carbon steel, stainless steel, aluminium, copper alloys and non-ferrous components
Dearomatised solvent — barium free	Low-odour formulation for worker comfort. Free from heavy metals including barium — improved environmental and health profile vs legacy rust preventives
Medium flash point — limits evaporation and fire risk	Safer to use and store in offshore and port environments compared to high-solvent, low-flash-point alternatives
Easily removed with alkaline or solvent cleaners	No specialist removal process required — standard workshop cleaners are sufficient when accessing protected components for inspection or use

Protection Duration
