Description
Sulphonyl diisocyanate, with the chemical formula C8H4N2O4S2, is a highly reactive diisocyanate compound characterized by the presence of two isocyanate functional groups. This feature allows it to readily crosslink with polyols, facilitating the formation of polyurethane polymers. Renowned for its high reactivity and swift curing properties, Sulphonyl diisocyanate plays a pivotal role in the production of a diverse range of polyurethane products. However, it is also recognized as a potent sensitizing agent, which can trigger allergic responses in certain individuals, necessitating stringent safety measures during its handling.
Uses
Used in Polyurethane Production:
Sulphonyl diisocyanate is utilized as a key ingredient in the manufacturing process of polyurethane foams and coatings. Its ability to crosslink with polyols results in the creation of polyurethane polymers, which are valued for their versatility and performance in various applications.
Used in the Foam Industry:
Within the foam industry, Sulphonyl diisocyanate is employed as a reactive component for producing polyurethane foams. Its high reactivity and fast curing properties contribute to the efficient production of foams with desirable characteristics, such as flexibility, durability, and insulation properties.
Used in the Coatings Industry:
In the coatings industry, Sulphonyl diisocyanate is used as a critical component in formulating polyurethane coatings. The resultant coatings offer excellent adhesion, abrasion resistance, and chemical resistance, making them suitable for a wide array of applications, including automotive, industrial, and protective coatings.
Safety Precautions:
Given its strong sensitizing potential, Sulphonyl diisocyanate requires careful handling to prevent allergic reactions in susceptible individuals. Appropriate safety measures, such as the use of personal protective equipment and proper ventilation, should be implemented during its production, storage, and application processes.
Check Digit Verification of cas no
The CAS Registry Mumber 4223-09-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4223-09:
(6*4)+(5*2)+(4*2)+(3*3)+(2*0)+(1*9)=60
60 % 10 = 0
So 4223-09-0 is a valid CAS Registry Number.
