John Burn Introduce the Sprayomer Bio-Based Reusable Vacuum Bag

Green technology ensures a cost-efficient production process

BildSprayomer™ Elastomer provides a cost-effective “Green” solution over conventional vacuum bagging films.

Whether you work with polyester, vinylester or epoxy resins, the Sprayomer eliminates considerable waste stream associated with typical bagging films and systems and is a reliable, durable and environmental friendly solution.


  • Eliminates consumables and resin waste

  • Gain control over bag bridging and wrinkles
  • Build seamless, netshape vacuum bags in any size or shape
  • Tear resistant bags are lightweight, durable and easy to handle
  • Silicone-free single component material, cleans up with distilled water

  • Durable – 250 parts from one bag
  • Flexible – 600% elongation
  • Seamless – No leakage, unlimited moldsize
  • Repairable – Easy to repair with a brush
  • Sprayable – Perfect net-shape
  • Low Permeability – Effective diffusion barrier
  • Prevulcanised – No catalyst needed, 1K
  • Solvent free – Water based
  • Puncture resistant – Durable no reinforcement needed
  • Silicone-free – No problem bonding or painting
  • Time saving – No need to search for leakages
  • Minimise Waste – No foil or tacky tape needed

Production of a SprayomerTM bag
Sprayomer is sprayed on to your mould with a the Quick Mold SprayerTM. This heated airless spraygun is able to spray bags of 1,5mm – 2mm thickness . A few layers is enough to produce a highly elastic, vacuum tight bag. The material cures overnight and is ready to use very shortly after that.

Airtight Sealing
To connect the vacuum bag airtight to your mould we use a Zipperseal. This consists of two rubber parts that work similair to a zipper. One part is bonded onto the mould, the other part is integrated into the Sprayomer vacuum bag. The bag is in place and vacuum tight in minutes.

Vacuum transport throughout the bag
To ensure a full vacuum, an air/resin transport strip (Waste Fluid Transfer Conduit, WFTC) is sprayed inside the bag. The structure of the strips surface is copied into the Sprayomer bag and can transport air.
