Product Description

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.

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.

Application

Wanhua PM200 isocyanate curing agent is a commonly used curing agent, widely used in coatings, adhesives, elastomers and other fields. Its main features include fast curing speed, low viscosity, good chemical stability and good temperature resistance1.

Application fields
Coating industry: Wanhua PM200 isocyanate curing agent can be used in various types of coatings, including water-based coatings and solvent-based coatings, and can improve the drying speed and hardness of the coating film12.
Adhesive industry: This curing agent is used for the curing of various adhesives, which can improve the adhesion and temperature resistance of adhesives1.
Elastomer industry: In the manufacture of elastomers, Wanhua PM200 isocyanate curing agent can be used as a cross-linking agent to increase the strength and wear resistance of elastomers12.
Other fields: In addition, this curing agent is also used in the manufacture of polyurethane rigid foam insulation materials, isocyanurate foam, anti-seepage plugging, structural foam, microporous self-skin foam, automobile bumpers, interior parts, high resilience foam and synthetic wood, etc.23. Instructions and precautions
Instructions:

Preparation: Stir the curing agent thoroughly.
Mixed curing agent: Add the curing agent to the base material of the coating, adhesive or elastomer according to the formula requirements and stir evenly.
Curing process: Curing treatment can be carried out by heating or oxidation.
Testing the curing effect: The cured product should undergo necessary testing methods to ensure that the required curing effect is achieved1.
Precautions:

Operating environment: When using, a well-ventilated working environment should be maintained to avoid inhaling curing agent vapor.
Protective measures: Appropriate protective equipment such as gloves and protective glasses should be worn during operation to prevent the curing agent from irritating the skin and eyes1.
