The Dow Performance Fluids Business anticipates increased demand for UCON™ TRIDENT AW Hydraulic Fluids because of its environmentally friendly performance profile and increasingly strict environmental regulations. Ship and dock operators, tunnel boring companies, loggers and even amusement park operators benefit fromUCON™ TRIDENT AW Fluids because they are readily biodegradable, fire resistant, and offer low aquatic toxicity to fish and wildlife.

UCON™ TRIDENT AW fluids have excellent anti-wear properties over a wide temperaturerange.These polyalkylene glycol (PAG) based fluids are available from Dow in three different grades and can be sourced through American Chemical Technologies (www.americanchemtech.com) in NorthAmerica and are available globally by contacting The Dow Chemical Company.

The Importance of Hydraulic Fluids

Hydraulic fluids are the workhorses of the systems they help run. Hydraulic fluids transmit power,lubricate and help cool equipment and prevent rust and corrosion. Viscosity is the strength of the fluids' cohesive force. It determines fluid friction and the drag moving parts exert, which pulls fluid over and between metal surfaces.UCON™ TRIDENT AW Fluids have a broad operating range and can replace two or threeviscosity grades of other, traditional fluids. Further, these fluids do not have to be changed outseasonally as do fluids like mineral oil. This feature is another money saver as companies using UCON™ TRIDENT AW Fluids do not have to shut down as frequently for maintenance and fluidchange out.

Features & Benefits of UCON™ TRIDENT AW Fluids

• Biodegradability: UCON™ TRIDENT AW 32 Fluid is readily biodegradable according toOEDC 301B, while UCON™ TRIDENT AW 46 and 68 fluids are inherentlybiodegradable, also according to OEDC 301B standards.

• Low Aquatic Toxicity: According to the U.S. Fish and Wildlife Service, UCON™TRIDENT AW Hydraulic Fluids meet requirements as "relatively harmless" or"practically non-toxic" to fish and other aquatic wildlife.

• No floating sheen on water: UCON™ TRIDENT AW Fluids are heavier than water,dissolve completely, and therefore leave no surface sheen, which can simplify cleanup andsecondary water treatment requirements.

• Fire resistance: FM Approvals, using the latest test procedures, has classified UCON™TRIDENT 46 AW and 68 AW as "Approved Industrial Fluids", and UCON™ TRIDENT32 AQ as a specification tested material.
