Important Two-Component Material Information

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.

Keep Components A and B

Moisture Sensitivity of 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.

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.

Separate

Foam Resins with 245 fa Blowing Agents

Some foam blowing agents will froth at temperatures

above 90°F (33°C) when not under pressure, especially Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination of the equipment’s wetted parts, never interchange component A (isocyanate) and component B (resin) parts.

313872B 11

if agitated. To reduce frothing, minimize preheating in a

circulation system.

Page 12

Important Two-Component Material Information

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 ISOontheBside.

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

A (Red) and B (Blue) Components

IMPORTANT!

Material suppliers can vary in how they refer to plural component materials.

Be aware that when standing in front of the manifold on proportioner:

• Component A (Red) is on the left side. The A (Red) side is intended for ISO, hardeners, and catalysts.

• Component B (Blue) is on the right side.The B (Blue) side is intended for polyols, resins, and bases.

For ratios higher than 1:1, the higher volume is typically the B (Blue) side.

• Most polyurethanes use ISO on the A (Red) side and polyol on the B (blue side, but some use ISO on the B (Blue) side.

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

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

• Silicones often have the catalyst on the B side.

Loss of Air Pressure

Purge rod actuation is controlled by air pressure. In event of loss of air pressure, the purge rod will remain retracted, the impingement ports will remain open, and the gun will continue to pour. To stop pouring, do one of the following:

• Engage piston safety lock, see Piston Safety Lock section

• Close fluid valves A and B, see FIG.3

Hook Support

If necessary, use the hook support located on the top of the gun to support the weight of the gun. Connect a strong rope or chain able to support the weight of the gun to the hook, then connect the other end to a support. This will enable the user to use the gun without having to support the weight of the gun.

Adjust Orifices

In order to balance pressures between the A component and B component the needle in each orifice may need to be adjusted. Be sure that all necessary adjustments to the proportioner are made prior to adjusting the orifices, see proportioner manual.

If after adjusting pressures neither orifice can achieve the desired pressure both orifices should be replaced with a larger or smaller size. Note that a smaller orifice will provide higher pressure and a larger orifice will provide lower pressure.

If after attempting to balance pressures the pressure difference is over 500 psi one orifice should be replaced with a different size. If that is the case, adjust the needle in each orifice all the way open (counter-clockwise) and observe the pressures. The orifice whose pressure is farthest from the desired pressure should be replaced. Note that a smaller orifice will provide higher pressure and a larger orifice will provide lower pressure.

1. Insert a 5/64 in. hex key (supplied) into the opening in the hex on the orifice.

16. Perform a test pour into a waste container. Adjust pressure and temperature to get desired results, see proportioner manual. Also, see Adjust Ori- fices.
