WM 8678

WM 8678 is a liquid Molybdate based corrosion inhibitor designed for use in closed recirculating water
systems such as chilled water loops and combined
chilled-hot water loops. It is a newly developed
formulation that combines organic and inorganic
chemicals which act synergistically to form a
continuous film to protect both ferrous and nonferrous
metal surfaces against pitting and general
corrosion. It also prevents scale formation and
conditions the sludge for easy removal through blowdown
or bleed off.

WM 8688

WM 8688 is a liquid borax pH adjuster designed for
use in closed recirculating water systems such as hot
water, chilled water and glycol loops. It is designed to
raise the system pH to provide optimum corrosion
protection.

WM 8703

WM 8703 is a highly effective Thermal Fluid and Heat
Transfer Fluid Corrosion Inhibitor. Corrosion protection is
one of the most important duties of a Thermal Fluid. WM
8703 contains extra-strength corrosion inhibitors designed
to protect all metals commonly found in HVAC and other
heat transfer systems. The effectiveness of WM 8703 in
preventing corrosion has been proven both in use and in
extensive laboratory testing. WM 8703 is CFIA approved for
use in registered food plants. WM 8703 does not contain
molybdates, nitrites or borax, eliminating environ- mental
and toxicity concerns.

WM 9400

A ready-to-blend, stabilized, bacterial spore liquid concentrate designed to biologically digest and deodorize organic wastes.

WB 8102

WB 8102 is an alkaline liquid treatment designed for
use in steam boilers where adjustment of alkalinity is
required.

WB 8138

WB 8138 neutralizing corrosion inhibitor is a blend of
three volatile amines designed for use in steam
systems. The three-amine blend provides distribution
ratio synergy, such that 1 product will neutralize
carbonic acid formation in the entire steam/
condensate run. This blend of amines will condense to
neutralize low pH where condensate first forms,
midsections, off runs from the main, lags and also the
farthest reaches of the condensate system.

WB 8299

WM 8299 is a 100% active liquid anti foam. It
effectively prevents air entrainment, froth and foam
generation in a variety of operations. It coalesces
minute air bubbles in the liquid, allows them to rise
easily to the surface, and promotes rapid bubble-film
rupture on the surface of the liquid.

WB 9211

WB 9211 is a concentrated blended liquid metal
passivator / oxygen scavenger formulated to control
oxygen “pitting” corrosion in steam boiler systems
operating below 600 psi. WB 9211 functions primarily
through passivation of existing corrosion sites and
creation of passive oxide protective films on metal
surfaces.

WC 8302

WC 8302 is a low molecular weight, very high charge
density cationic polyamine. It is supplied as a clear to
opaque liquid, low viscosity aqueous solution. WC
8302 operates over a wide pH range and is effective
at low dosages. WC 8302 controls organic deposits
and improves heat transfer in cooling systems.

WC 8304

WC 8304 is a microbicide concentrate with broad
effectiveness against microorganisms that cause the
fouling of, and loss of efficiency in industrial water
systems. The product is used for the following specific
applications:
1. Controlling sulfate-reducing bacteria in
petroleum water flood systems
2. Controlling algae, bacteria, and fungi in
recirculating commercial and industrial cooling
water systems
3. Controlling bacteria in industrial air washers

WM 8565

WM 8565 is a concentrated caustic based liquid
cleaner formulated to remove oil, grease and
particulates in new and retrofit steam boilers prior to
operation. WM 8565 is suitable for all steam
applications where rapid boiling will ensure total
contact and provide some scouring action. WM 8565
is formulated to be 3 - 5 times more effective than
standard alkaline cleaners in removing oil and grease
preservatives as well as metal oxides and particulates.
Cleaning time of 4 - 6 hours is normally adequate.

WM 8570

WM 8570 represents a new generation of scale
removers and industrial strength cleaners. The major
ingredient is an acidic organic salt which provides
hard water scale removal capabilities exceeding those
of most mineral acids. WM 8570 is an excellent
replacement for sulfamic acid and will outperform
other organic acids. WM 8570 contains inhibitors and
dispersants to facilitate deposit removal with minimal
effect on system metallurgies.

WM 8580

WM 8580 represents a new generation of a liquid water
treatment where adjustment of alkalinity is required. The major ingredient is an acidic organic salt which provides alkalinity and pH reduction in water systems. WM 8580 is an excellent replacement for sulfuric acid and will out-perform other organic acids. WM 8580 is relatively innocuous to humans and is classified as a mild skin irritant. When used as directed it is safe for use with most metals. WM 8580 is much safer and easier to use than sulphuric acid.

WM 8587

WM 8587 has long been known as an effective
compound for a variety of uses in the water treatment
industry. In cooling water, it is used both as a
biodispersant and as a dispersant that allows organic
contamination to be removed by bleed. In badly
corroded systems it assists in the breaking up and
removal of tubercles under which corrosion occurs. It
also inhibits further corrosion. In boiler water systems
it functions as a filming amine to protect condensate
system piping.

WM 8588

WM 8588 is intended for the removal of dirt, oil, and grease
surface rust that is found on new piping. This new piping may be part of a new system or an addition to an existing closed loop circuit.

WM 8600

WM 8600 is a 100% active liquid anti foam. It
effectively prevents air entrainment, froth, and foam
generation in a variety of operations. It coalesces
minute air bubbles in the liquid, allows them to rise
easily to the surface, and promotes rapid bubble-film
rupture on the surface of the liquid.

WM 8676

WM 8676 is a liquid Nitrite based corrosion inhibitor
designed for use in closed recirculating water systems
such as chilled water loops and combined chilled-hot
water loops. It is a newly developed formulation that
combines organic and inorganic chemicals which act
synergistically to form a continuous film to protect
both ferrous and non-ferrous metal surfaces against
pitting and general corrosion. It also prevents scale
formation and conditions the sludge for easy removal
through blow-down or bleed off.
