26. ure Sensitivity of Isocyanates 4 311882T 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 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 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 Part 217374 ISO pump oil or grease when reassembling Isocyanate Hazard Foam Self Ignition Keep Components A and B Separate Changing Materials When changing materials flush the equipment multiple times to ensure it is thoroughly clean Check with your material manufacturer for chemical compatibility Some materials use catalyst on the A side but some applications may use catalyst on the B side Epoxies often have amines on the
