When time is of the essence
Bote-Cote accelerator is a unique chemical that is totally compatible with epoxy resin and hardeners.
Small additions (a few percent) of accelerator catalyse the normal epoxy reaction, yet have no effect on the strength or any other properties of the final epoxy adhesive or coating. Bote-Cote accelerator presents users with a convenient system for controlling reactivity in response to changes in temperature, mix quantity, or desired setting rate. Users need to keep a stock of just one slower setting epoxy, such as Bote-Cote Standard Hardener, and can increase its reactivity at will according to their requirements. This represents a considerable economy in inventory, as well as avoiding possible waste from using an inappropriate hardener for the particular job in hand.
Typical reaction times (for standard 100 gm cup tests) are as follows:
|Time to Gel. (Minutes)
|Bote-Cote Standard Hardener
Please note, the cure of room temperature curing epoxies at temperatures less than 15ºC is often difficult. In particular, it takes the gelled epoxy a long time to reach near full strength when the temperatures are low. (Days, weeks or more). The use of accelerator instead of arranging to work in suitable temperatures is not considered to be best practice. We have supplied Gel Times for larger amounts of accelerator in good faith, however, it is possible that such large amounts could compromise the properties of the cured epoxy. Prior to deciding to use more than a few percent, the user should do a trial to ensure that the result is acceptable.
