Dahltexx® SP-3

Dahltexx® SP-3 is an air permeable fabric which can be used for techniques such as toolside breathing and bag side breathing to aid the removal of air but still contain resin. Due to a micro-porous membrane the Dahltexx® SP-3 fabric will allow the passage of air and restrict the flow of resin. Dahltexx® SP-3 is better at containing lower viscosity resin types.

Benefits

Dahltexx® SP-3 membrane contains resin in the part area to maintain vacuum and avoiding resin waste

Dahltexx® SP-3 is a fabric membrane permeable to air but not resins, suitable for very low viscosity resins.
It can be used for higher temperature infusions where low viscosity resin needs to be contained.
More complicated higher quality void free laminates achieved with all over vacuum applied through infusion process.
