Important Two-Component Material Information

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 crystal- lization 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 con- taminated from the other side.

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

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 if agitated. To reduce frothing, minimize preheating in a circulation system.

Changing Materials

•When changing materials, flush the equipment mul- tiple 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.
