Overview

Usage

XM plural-component sprayers can mix and spray most

two-component epoxy and urethane protective coatings.

When using quick-setting materials (less than 10 minute

pot life) a remote mix manifold must be used.

XM plural-component sprayers are operated via user

interface, air controls, and fluid controls.

Isocyanate Hazard

Material Self-Ignition

Moisture Sensitivity of

Isocyanates

Isocyanates (ISO) are catalysts used in two component

urethane coatings. ISO will react with moisture (such as

humidity) to form small, hard, abrasive crystals, which

become suspended in the fluid. Eventually a film will

form on the surface and the ISO will begin to gel,

increasing in viscosity. If used, this partially cured ISO

will reduce performance and the life of all wetted parts.

NOTE:

The amount of film formation and rate of crystallization

varies depending on the blend of ISO, the humidity, and

the temperature.

To prevent exposing ISO to moisture:

• Always use a sealed container with a desiccant

dryer in the vent, or a nitrogen atmosphere. Never

store ISO in an open container.

• Use moisture-proof hoses specifically designed for

ISO, such as those supplied with your system.

• Never use reclaimed solvents, which may contain

moisture. Always keep solvent containers closed

when not in use.

• Never use solvent on one side if it has been contam-

inated from the other side.

• Always park pumps when you shutdown.

• Always lubricate threaded parts with Part 217374

ISO pump oil or grease when reassembling.

XM OEM sprayers are not approved for use in hazard-

ous locations.

Spraying materials containing isocyanates creates

potentially harmful mists, vapors, and atomized partic-

ulates.

Read material manufacturer’s warnings and material

MSDS to know specific hazards and precautions

related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and

atomized particulates by providing sufficient ventila-

tion in the work area. If sufficient ventilation is not

available, a supplied-air respirator is required for

everyone in the work area.

To prevent contact with isocyanates, appropriate per-

sonal protective equipment, including chemically

impermeable gloves, boots, aprons, and goggles, is

also required for everyone in the work area.

Some materials may become self-igniting if applied

too thick. Read material manufacturer’s warnings and

material MSDS.

Location

Components A and B

IMPORTANT!

Material suppliers can vary in how they refer to plural

component materials.

Be aware that in this manual:

Component A refers to resin or major volume.

Component B refers to the hardener or minor volume.

NOTE:

This equipment doses the B component into the A com-

ponent flow. An integration hose must always be used

after the mix manifold and before the static mixer.

NOTE:

Please follow these recommendations for setup:

• use at least a 3/8 in. (10 mm) x 25 ft. (7 m) hose as

the integration hose.

• install a 24-element static mix tube after the integra-

tion hose.

Keep Components A and B Separate

Changing Materials

• When changing materials, flush the equipment mul-

tiple times to ensure it is thoroughly clean.

• Always clean the fluid inlet strainers and outlet filter

after flushing, Flush Mixed Material, page 16.

• Check with your material manufacturer for chemical

compatibility.

• Epoxies often have amines on the B (hardener)

side. Polyureas often have amines on the A (resin)

side.

NOTE:

If the amine will switch between the two sides, see

Flush Mixed Material, page 16.

Location

Grounding

Ground control box (ground wire attached) and both air

motors to a true earth ground.

NOTE:

If wall power is used, ground electrical connection prop-

erly according to local codes.

NOTICE

To prevent cross-contamination of the equipment’s wet-

ted parts, never interchange component A (resin) and

component B (hardener) parts.
