XPREG® XA120 Prepreg Adhesive Film, 150g (1250mm) - 1m Roll

XPREG® XA120 is a structural epoxy adhesive film used to provide a high strength bond between composite laminate and core materials such as aluminium honeycomb, Nomex® or foam core (such as Rohacell®). This film adhesive can also be used to provide additional resin around bonding fasteners and inserts or underneath peel-ply when using peel-ply to provide a secondary bonding surface.

XA120's advanced, toughened epoxy formulation results in outstanding bond and peel-strength at the very forefront of adhesive film performance.

This prepreg resin film is suitable for autoclave, oven or heated platen press cure. XA120 cannot be cured at room temperature.

Features

• Industry leading bond and peel-strength
• Service temperature up to 120°C (subject to post-cure)
• Easy handling (4 week out-life)
• Minimal shrinkage, very low CTE
• Fully compatible with XPREG® XC110 and XC130 prepregs

Cure Cycle

The recommended cure cycle for XA120 is 8hrs at 90°C (ramp rate 2°C/min) which will result in a Tg of 100°C. Where the maximum Tg is required, a post cure of 120°C for 1hr should be followed (ramp rate 0.3°C/min).

See datasheet for full details including alternative cure cycles from 80°C.

Compatibility with XPREG® Prepregs

XA120 is fully compatible with XPREG° XC110 (out-of-autoclave) and XC130 (autoclave) cure prepregs and can be co-cured with these prepreg systems or used in a '2-shot' process to provide secondary bonding onto laminates made using these systems (peel-ply finish or surface preparation would be required).
