Dry Formula -

Use the dry formula when mold downtime is at a minimum. Dry formula is easy to clean up and get the mold back into production quickly. It is self-cleaning in startup, thus eliminating the need to flush off with a cleaner. The dry formula will naturally “flash off” within the first few shots of plastic. A non-penetrating mist prevents marking of plastic parts when molds are put back in service. Also use Dry formula on “sweaty molds” to protect against condensation created during the cooling down process.


  • Dry coating is quick and easy to clean up!
  • Self-cleaning in startup.
  • Seals out condensation.
  • Up to 2 year protection indoors.
