Hold can perpendicular 6” to 8” from the surface being sprayed. Typical woven composite fabrics only need 1 dry gram / square foot to hold up to 6 layers vertically. Depending on layup and type of material, more adhesive may be needed.
- When using Infusion Mesh more 3M Adhesive 71 may be needed to avoid edge curling.
- Higher temperatures reduce normal storage life. Lower temperatures may cause increased viscosity of a temporary nature.
