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 thick. 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 pump wetcup or reservoir (if installed)
filled with Graco Throat Seal Liquid (TSL
206995. The lubricant creates a barrier between the ISO and the atmosphere.
Use moisture-proof hoses specifically designed for ISO.
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 TSL or grease when reassembling.

Foam Resins with 245 fa Blowing Agents

Some foam blowing agents will froth at temperatures 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.

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

Changing Materials

Changing material types used in your sprayer requires special attention to avoid equipment dam­age and downtime.
Always clean the fluid inlet strainers after flushing.
When changing between epoxies and urethanes or polyureas, disassemble and clean all fluid compo­nents and changes hose sets.
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.

Overview
The left side of the mix manifold is intended for the major volume material, or the higher viscosity material if using a 1:1 volume mix. This side is referred to throughout the manual as the resin side or “A” side.
The right side is referred to as the Hardener side or “B” side. The “B” side incorporates an adjustable restrictor for balancing the system back pressure and flow.
See FIG. 2 to view flow of “A” and “B” material inside the Mix Manifold.
“A” Inlet Ball Valve
F
The resin and hardener enter the mix manifold through the manifold inlet ports and spring loaded carbide ball checks. The “A” material flows through the manifold to the material outlet port. The injector tube creates a hollow stream of “A” material for the “B” material to fill once the hardener exits the injector tube. The resin and hardener material mix after they have left the mix manifold block (B).
When the manifold is mounted remote from the propor­tioner, adjust the “B” side restrictor (F) to balance the sys­tem back pressure and flow.
On the standard mix manifold, mixed material is flushed out by sending a flush solvent through the B side center tube. On the quickset mix manifold, solvent is also flushed across the A side fluid check valve.
