Cobalt
Chekad produces Cobalt accelerators for hardening and curing resins and gelcoats.Chekad cobalt types are as below:
AC-1000 Cobalt accelerator is based on cobalt naphthenate and it’s characterized by following features:
- More efficient than ordinary cobalt naphthenate such that you can save cobalt usage up to 10-15% compared to ordinary one.
- Suitable efficacy in temperature range of 10-25oc.
- Decreased cure time (without decreasing pot life during apply)
- Increase three dimensional polymer network.
- Providing more stiffness and solidity for building final part.
AC-1000 package is 5kg and 18kg plastic cans.
AC-2000 Cobalt accelerator is used for white and light-colored Gelcoats.
This product is an accelerator for hardening and curing particularly white and light-colored Gelcoats, since AC-2000 creates subtle color change on the finished product.
Some of its features are as follows:
- No negative impact on gel time and curing time of resin
- No color changed will occur at final products
- Dosage based on 25°C temperature would be: 0.2- 0.45 %
AC-2000 package is in 5kg and 18kg plastic cans.
Chekad Cobalt Accelerator – 10%
Chekad is a manufacturer of a 10% cobalt accelerator designed to promote the curing process of unsaturated polyester and vinyl ester resins at ambient temperature. It is recommended to use this cobalt accelerator at a dosage of 0.5% by weight of the total formulation. However, this amount should be adjusted depending on the type of resin used.
The shelf life of this product is one year when stored in tightly closed containers within a temperature range of 5°C to 30°C, in a dry, well-ventilated environment.
Important: Direct contact between cobalt and peroxide must be strictly avoided.
