Final answer:
The flash-off time for Sika Activator Pro at temperatures between 0-15 degrees Celsius is the waiting period after application for the solvent to evaporate. It varies with environmental conditions, and the manufacturer's technical data sheet or direct inquiry is recommended for specific guidance.
Step-by-step explanation:
The flash-off time for Sika Activator Pro at temperatures between 0-15 degrees Celsius refers to the required waiting period after application of the activator and before the adhesive application.
This period allows the solvent in the activator to evaporate and the activator to properly prepare the substrate surface for the adhesive bonding process. Sika recommends a general flash-off time; however, the specific flash-off time can vary based on environmental conditions.
It is generally recommended to consult the Sika Activator Pro technical data sheet or contact the manufacturer for specific guidance in harsh or extreme temperature conditions, as colder temperatures can prolong the flash-off time required for optimal adhesion.
