1. Application

Modified MDI, is a mixture of polyol-modified diphenylmethane diisocyanate and

polyphenylmethane polyisocyanate. It is a brown liquid at room temperature. It can be main

used in the production of slow rebound foam.

4. Storage

Since XCG-6606A 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 XCG-6606A should be kept properly closed and stored indoors at ambient

temperatures (20-25℃) in a well-ventilated area. Storage at low temperatures (below 10℃)

may lead to some crystallization; this material must, therefore, be protected from frost. If

crystallization does occur, the material should be heated to 60-70℃ to melt it out, strictly

prohibit to heat over at local part and should then be thoroughly agitated before use.

Since XCG-6606A is very easy to react with moisture and leads to the formation of carbon

dioxide gas, containers must therefore be absolutely dry and sealed to protect from

moisture and water. In case water splashes into the containers, be careful to avoid sealing

it too tightly. It is important to leave holes to prevent containers from explosion.

5. Shelf Life

Under recommended storage conditions, the shelf life of XCG-6606A is 12 months. If the

production is overdue, but it’s main physical and chemical properties in the guide line, may

not effect on its using properties.

6. Safety

XCG-6606A is of low toxicity by inhalation and skin absorption. The very low volatility of

XCG-6606A means that it should be of little hazard for brief exposures under normal

conditions, e.g. in cases of small spillages.

Nevertheless, XCG-6606A is an isocyanate-based composition and should be of certain

toxicity. It may cause mild eye irritation and slight skin irritation. It may pose problems of

skin sensitization. XCG-6606A has a Ceiling Threshold Limit Value, TLV(C) of 0.02ppm

(0.2mg/M3 ). It is important to note, however, that a vapour hazard will arise if the material

is heated to temperatures above 40℃, or if it is reacted in an unventilated space. Another

hazard is the formation of air-borne droplets during spraying operations. Under such

conditions, it is essential to wear a gas mask and a respirator since repeated inhalation of

the vapour at levels above the TLV(C) could cause respiration sensitization.
