Flexitec - Powder Hardener 1kg - (1kg per 20kg Resin)

Flexitec requires powder hardener at a minimum of 2% and a maximum of 4% depending on temperature. 
To ensure that the curing process is not impeded: 
Never use less than 2% even in hot conditions 
Never use more than 4% even in cold conditions. 
Always test the pot life in the prevailing conditions by performing a test mix at the suggested powder hardener level before you start application. 
Adjust powder hardener levels up or down as required to gain the pot life you require. Remember it is always possible to use intermediate levels (e.g. 2.5%) to gain close control of the pot life. 
It is not recommended to catalyse more than ~5 kg at a time. When working large areas decant the primer into manageable quantities and always be aware of your pot life.
