    Polyphenylene Isocyanate Diisocyanate-Diphenylmethane MDI PM-200

    1, General Description
    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.

    4, Application:
    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 which
    require strict flowability of systems.
    5, Storage properties:
    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 (15-35) in a well-ventilated area. Storage at low temperature (below
    5) 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 70-80 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 50 is not recommended to prevent from the
    formation of insoluble solids and viscosity increase.
    6, Handing precautions:
    Product may cause skin and eye irritation. In cases of skin contact wash
    immediately with soap and water. For eyes, flush with plenty of water for 15
    minutes and seek medical attention immediately.
    Under recommended storage conditions, the shelf life of WANNATE® PM-200 is one year
    since the date of production.
