Description
Solvent Red 149 is a brilliant blue light red dye that is commonly used for coloring thermoplastic resins. It has a stable melting point and exhibits good light fastness and heat resistance.
Uses
Used in Plastic Industry:
Solvent Red 149 is used as a coloring agent for thermoplastic resins due to its brilliant blue light red color. It provides a stable and long-lasting color to the plastic materials, enhancing their appearance and aesthetic appeal.
The dye is also heat-resistant, allowing it to withstand high temperatures during the manufacturing process without losing its color intensity. This makes it suitable for use in the production of various plastic products, such as toys, packaging materials, and automotive components.
Furthermore, Solvent Red 149 demonstrates good light fastness, ensuring that the colored plastic products maintain their vibrant color even when exposed to sunlight or artificial light sources for extended periods.
In addition to its use in the plastic industry, Solvent Red 149 may also find applications in other industries where coloring of thermoplastic resins is required. Its heat resistance, light fastness, and stable melting point make it a versatile dye for various applications.

Check Digit Verification of cas no
The CAS Registry Mumber 71902-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,0 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71902-18:
(7*7)+(6*1)+(5*9)+(4*0)+(3*2)+(2*1)+(1*8)=116
116 % 10 = 6
So 71902-18-6 is a valid CAS Registry Number.
