cross-linking activator particularly for fluoro elastomers used to achieve optimal compression set values at higher temperatures. It is normally used in combination with a fine particle size magnesium oxide. Packing Size: 9 kgs. Available Forms: Powder Technical Data Sheet Product Name : JC EG - 81 Function : Filler and Acid scavenger in FKM and other rubber and plastics. Technical Name : Calcium Hydroxide CAS No : 1305-62-0 Appearance : White Powder Calcium Hydroxide % ; 97.0 Min Sieve Residue (325 Mesh)% : 0.5 Max Moisture Content % : 1 Max Mode of action : JC EG - 81 is a cross-linking activator, particularly for fluoro elastomers used to achieve optimal compression set values at higher temperatures. It is normally used in combination with fine particle-size magnesium oxide. Processing : It is advisable to add JC EG - 81 together with the fillers or straight afterward, As JC EG - 81 is very hygroscopic therefore should, not be weighed until just before the incorporation in the mix Dosage : Normally 6-7 PHR JC EG - 81 in combination with 3PHR Magnesium oxide Packing : 9X1Kg EVA/PP Packet per box Storage : Stored in cool and dry atmosphere Advantages cross-linking activator particularly for fluoro elastomers used to achieve optimal compression set values at higher temperatures.
