311075U 7

Overview

The Reactor E-10 is a portable, electric-powered, 1:1 mix ratio proportioner, for use with a wide variety of coatings, foams, sealants, and adhesives. Materials must be self-leveling and pourable, and may be applied with impingement mix spray guns, disposable mixer guns, or flush-type mix manifolds.

Reactor E-10 is gravity-fed from 7 gal. (26.5 liter) supply tanks mounted on the unit. The tanks are translucent to allow monitoring of fluid level.

Severe duty, positive displacement reciprocating piston pumps meter fluid flow to the gun for mixing and applying. When set to recirculation mode, Reactor E-10 will circulate fluids back to the supply tanks.

Heated models include separate thermostatically controlled heaters for each fluid, and an insulated hose bundle with circulation return hoses. This allows the hoses and gun to be preheated to the desired temperature before spraying. Digital displays show the temperatures of the two fluids.

Reactor E-10 has two recirculation speeds, slow and fast, and an adjustable pressure output.

Slow Recirculation

• Slow circulation results in a higher temperature transfer in the heater, so hoses and gun heat up quicker.

• Good for touchup or low flow spraying, up to moderate temperature.

• Not used to circulate full tanks up to temperature.

• Use with 245 fa blowing agent foams, to minimize heat returned to tank and reduce frothing.

Fast Recirculation

• Use to support higher flow rates or higher temperatures by preheating the tanks.

• Agitates fluid within tanks, to avoid heating only the fluid at the top of the tank.

• Use for flushing.

An electronic processor controls the motor, monitors fluid pressures, and alerts the operator if errors occur. See STATUS Indicator, page 13, for further information.

8 311075U

Pressure Adjust

Automatically maintains selected pressure output for dispensing or spraying.

Isocyanate Hazard

Spraying 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.

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.

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 felt washers in the pump wet-cups saturated with Graco ISO pump oil, Part No. 217374. 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 (see page 63).

Foam Self-ignition

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

Moisture Sensitivity of

• 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 park pumps when you shutdown, see page 27.

• Always lubricate threaded parts with Part No. 217374 ISO pump oil or grease when reassembling.

Isocyanates

Isocyanates (ISO) are catalysts used in two component foam and polyurea coatings. ISO will react with moisture (such as humidity) to

311075U 9

Keep Components A and B Separate

NOTICE

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

Changing Materials

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

• Always clean the fluid inlet strainers after flushing, see page 28.

• 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.

Startup of Heated Units

Some models heat the fluid, which can cause equipment surfaces to become very hot. To avoid severe burns:

• Do not operate Reactor E-10 without all covers and shrouds in place.

• Do not touch hot fluid or equipment.

• Allow equipment to cool completely before touching it.

• Wear gloves if fluid temperature exceeds 110°F (43°C).

Perform Setup, pages 15-21.

Set function knob to Slow Recirc or

Fast Recirc . See Heatup Guide- lines, page 23, then continue with steps
