Product Description
WANNATE® PM-200
Application
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 which
require strict flowability of systems.
Typical Physical and Chemical Properties
Test Item(s) Specification(s)
Appearance Brown Liquid
Viscosity at 25ºC, mPa.S 150-250
NCO, % 30.5-32.0
Density 25ºC, g/cm3 1.220-1.250
Acidity (HCl), % ≤0.05
Hydrolysable Chlorin, % ≤0.2
Package(s)
210L iron drums, 250kg/drum
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.
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.

PM-200
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.
