VTF261 surfacing materials are based on Cytec's 'ZPREG®' selective impregnation surfacing technology and are recommended for use with the VTM®260 Series rapid lay-up prepregs and ZPREG materials. VTF261 surfacing materials are capable of achieving high quality cosmetic finish or paint ready surfaces direct from the mould.
In common with all VTM260 Series materials, VTF261 can be cured under vacuum bag pressure at temperatures between 65°C and 120°C (149°F and 248°F). The maximum end use service temperature is 100°C (212°F) after post- cure.
Differentially coated prepreg formats are recommended for relatively thin components where a clear cosmetic finish is required. ZPREG formats are recommended for large or thick components where flaw-free paintable surfaces may be achieved from standard tooling.
