EZ-Spray® Silicone 20 and 22
Technical Bulletin
MSDS
EZ-Spray® Silicone 20 and 22 are sprayable platinum-cure silicones that cure quickly to soft rubbers with high elongation and tear strength. Liquid silicone is sprayed through the EZ-Spray® Junior Cartridge System or SilCon® III Meter Mix and Spray Machine.

After a suitable thickness is attained, EZ-Spray® Silicone 20 cures in about 20 minutes while EZ-Spray® Silicone 22 cures in about 45 minutes. EZ-Spray® Silicone cures with negligible shrinkage to strong, durable and flexible finish suitable for production casting of polyester, epoxy or urethane resins, gypsum, concrete and other materials.

EZ-Spray® Silicone 20 and 22 silicones are effective for making reusable cost-effective vacuum bags fast for producing composite parts. Newly fabricated vacuum bags can be removed from the tool assembly in a matter of minutes and be put into production service immediately.

Advantages of Silicone Vacuum Bags:

  • Fast – as low as 4 hours from bag fabrication to part production.
  • Cost Effective Production after 8 cycles vs. consumable bags.
  • Reusable for hundreds of parts with polyester-based resins; upto 50 times with epoxy and 100 times when using pre-preg thermoplastic. Also suitable for de-bulk.
  • Reduce Labor – silicone bag is reset in minutes; no taping or pleating.
  • Self-Releasing – no release agents required.
  • Perfect Fit even for complex shapes and undercuts.
  • Odorless – No solvents or VOC's.
  • High Service Temperature – up to 464°F / 240°C.
  • Built-in Vacuum Seal.
  • Ideal for Wet Lay-Up, Infusion, Pre-Preg (in or out of autoclave), and De-Bulk.
Read the EZ-Spray® Junior or SilCon® III Equipment Manuals prior to spraying.
