SPECIALTY RUBBER CHEMICALS
Calcium Hydroxide C-2000
C-2000 is a cross-linking activator specially for fluoroelastomer. It is used in polyol & polyamine cure type fluoroelastomers. In both type fluoro rubber, magnesium oxide is used as acid acceptor and CALCIUM HYDROXIDE, C-2000 is used as cross linking activator. Magnesium Oxide 3 to 40 Phr can be absorbed in fluoroelastomers by adding C-2000 to reduce cost of compound.

Mode of Action :
Use of C-2000 improves properties such as high processing safety, very good stability of compound and optimum (low) compression set specially at high temperatures and high tensile strength.
Application :
- Add C-2000 6 Phr, magnesium oxide (Starmag® 150) 3 Phr to 5 Phr in polyol type fluoroelastomers
- Add C-2000 3 Phr polyamine cure type fluoroelastomers to improve metal to rubber bonding. Add min 15 Phr of low active magnesium oxide (Starmag® L)
- C-2000 should be added together with magnesium oxide and carbon black by premixing C-2000, magnesium oxide and carbon black, and then adding to masticated Fluoroelastomers.
Precaution of Handling :
C-2000 absorbs moisture quite fast, so please open container and measure just before adding to compound. Please seal the container immediate right after you take out necessary quantity from container
