Description

Dahltexx® fabrics are air permeable membranes which can be used for techniques to aid the removal of air but still contain resin. Due to the micro-porous structure of the Dahltexx® it will allow the passage of air and restrict the flow of resin. Dahltexx® is intended for vacuum only applications. Dahltexx® SP-3 has been developed to contain lower viscosity resin types and operate at elevated temperatures.

Benefits

• Improve laminate quality by releasing trapped air from resin infusions.

• Reduce resin waste by blocking resin flow into vacuum manifolds.

• Infuse more complex parts faster and with simpler resin flow lines.

Notes

• To achieve release from a cured laminate, the membrane should be placed fabric side down as the
membrane side is not self-releasing.

• The maximum use temperature is dependent upon the duration at maximum temperature and is process
specific, Airtech recommends testing prior to use.
