Viton® B-202
Viton® B-202 is designed to be cured with either Viton® Curative #30 or Viton® Curative #50. When using Viton® Curative #30, use Viton® Curative #20 in a ratio of about 1.8 Viton® Curative #30 to Viton® Curative #20. When using Viton® Curative #50, use 0.3-0.5 phr of Viton® Curative #20 to ensure a fast cure rate. Note that Viton® Curative #20 can be difficult to mix into low viscosity stocks, such as those based on Viton® B-202, and careful attention needs to be paid to mixing procedures
Compared with other B-family terpolymers, Viton® B-202 provides:
- Low viscosity
- Improved processing
- Increased mold flow
- Excellent mold release
Applications
- Transfer and injection molding of complex shapes
- Extrusions (e.g., fuel hose and tubing)
- Solution coatings of fabrics, tanks or chemical containers
Viton® B-202 can be blended with other Viton® types to modify viscosity, enhance processability and/or improve flow.
