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 Separate
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.

Shandong Reanin Machinery Co.,Ltd
K2000 Pneumatic Spray Machine User Manual

Moisture Sensitivity of Isocyanates
Isocyanates (ISO) are catalysts used in two component foam and polyurethane 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.
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 DOP. 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
loosed 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.
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 RED drum, and POLY on the BLUE drum.
