POLYMERIC PM200
Application
WANNATE ® PM-200 is a diisocyanate-diphenylmethane (MDI)-based composition containing
some higher functionality isocyanates. 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 flow
ability. It is, therefore, particularly suitable for the production which require strict flow
ability of systems.

Storage
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.
PM-200
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.
Shelf Life
Under recommended storage conditions, the shelf life of WANNATE ® PM-200 is one year
since the date of production.
