Isocyanate Conditions

Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates.

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 ventilation 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 personal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Material Self-ignition

Some materials may become self-igniting if applied too thickly. Read material manufacturer’s warnings and material MSDS.

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.

• Keep the ISO lube pump reservoir (if installed) filled with Graco Throat Seal Liquid (TSL), Part 206995. The lubricant creates a barrier between the ISO and the atmosphere.

• 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 contaminated from the other side.

• Always lubricate threaded parts with ISO pump oil or grease when reassembling.

Keep Components A and B Separate

NOTICE

To prevent cross-contamination of the equipment’s wetted parts, never interchange component A (isocyanate) and component B (resin) parts.

Moisture Sensitivity of

Blowing Agents

Some foam blowing agents will froth at temperatures

Isocyanates

Isocyanates (ISO) are catalysts used in two component foam and polyurea 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.

above 90°F (33°C) when not under pressure, especially if agitated. To reduce frothing, minimize preheating in a circulation system.

Changing Materials

• When changing materials, flush the equipment multiple times to ensure it is thoroughly clean.

• Always clean the fluid inlet strainers after flushing.

• Check with your material manufacturer for chemical compatibility.

• Most materials use ISO on the A side, but some use ISO on the B side.

• Epoxies often have amines on the B (hardener) side. Polyureas often have amines on the B (resin) side.

Grounding

This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current.

Metering valve: attach ground wire from grounding lug to true earth ground. See Component Identification starting on page 15.

Fluid hoses: use only electrically conductive hoses.

Feed system components: attach ground wire from

grounding lug to true earth ground. See feed system manual for grounding points. See Related Manuals on page 3.

Fluid supply container: follow local code.

Solvent pails used when flushing: follow local code.

Use only conductive metal pails, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.

Overview

This plural component meter, mix, and dispense device accurately meters liquid and semi-paste materials.

The machine is ideal for a two-component application requiring very small and precisely mixed shots.

The ratio of the pneumatic cylinder area to pump shaft area provides the adjustable pressure intensification needed to move the separate liquids through the mixer with a flow rate suitable for production requirements.

The complete system is enclosed. Mixing of the two materials takes place only in the mixer at the final stage of metering valve operation. See Sequence of Opera- tion on page 27.
