Product Description Product DescriptionEnvironmentally Friendly Raw Materials For The Production Of High-elastic Foam And AdhesivesDescription:WANNATE? PM-200 is a diisocyanate-diphenylmethane(MDI)-based composition containing some higher functionality isocyanates. The functionality is about 2.6-2.7. It is a brown liquid at ambient temperatures.WANNATE? PM-200 can be widely used in the production of rigid PU foam heat-insulating materials; also used in isocyanurate foam, paints, adhesives, structural foam, cellular integral skin foam, automotive bumper and interior parts, high-resilience foam and synthetic wood, etc. Due to its unique composition structure, WANNATE? PM-200 can provide better flowability. It is, therefore, particularly suitable for the production whichrequire strict flowability of systems.PACKING SPECIFICATION :220KGS/Drum, Plastic drums Typical physical properties:Test Item(s) Specification(s)AppearanceBrown LiquidViscosity at 25oC 150-250NCO30.5-32.0Density 25oC1.220-1.250Acidity (HCl)≤0.05 Storage Recommendation:Since WANNATE? PM-200 is a reactive chemical, reaction with atmospheric moisture happens easily and leads to the formation of insoluble ureas and carbon dioxide gas, which can result in pressure build-up in closed containers and viscosity increase of the product. Containers must therefore be absolutely dry and carefully sealed after congested with nitrogen. Containers of WANNATE? PM-200 should be kept properly closed and stored indoors at ambient temperature (15-35oC) in a well-ventilated area. Storage at low temperature (below 5oC) may lead to some crystallization; this material must, therefore, be protected from frost. If crystallization does occur, the material should be heated by rolling the drum in a hot air oven at 70-80oC to melt it out, and should then be thoroughly agitated before use. Melting in a water bath is not recommended.Extended storage at temperatures above 50oC is not recommended to prevent from the formation of insoluble solids and viscosity increase.
