Factors of Selection
For the best results in lay down, through cure and ultimate performance of the coating, the selection of the correct Activator (and Reducer) is always of high importance.
Two of the biggest considerations when selecting the appropriate activator and reducer are:
- Ambient air temperature (the vehicle or unit will be sprayed in).
- The size of the job.
Failure to make the right selection can result in:
- Excess peel.
- Dry spray.
- Solvent entrapment.
- Solvent popping.
- Gloss loss, etc
