Accelerator F
F is delayed action medium speed Accelerator. It show the desirable properties of MBT (fast cure with flat optimum, excellent ageing properties and freedom from discoloration) but produce higher levels of tensile strength/modulus and have a greatly improved processing safety. It is widely used in hose, footwear, cables and various types of general mouldings. Typical dosage varies from1.0 - 1.5 phr in most applications.
Storage and Handling
Stable indefinitely under normal storage conditions. No special handling precautions are necessary. Normal precautions to avoid contact with skin and eyes should be followed. For eyes, flush with plenty of water and seek medical advice.
