VTC401
Epoxy Component Prepreg
Introduction
VTC401 is an epoxy resin system designed to give an initial cure at low temperatures or snap cure at high
temperatures with enhanced toughness, honeycomb bondability and higher service temperature, giving
greater flexibility in component manufacture. It can be supplied on a variety of fabrics in UD format to meet
your cost and manufacturing requirements.
Typical applications: General purpose Visual
Key Features & Benefits
Cure temperature from 150 F to 250 F
Service temperature up to 275 F after post cure
Low CTE and shrinkage
Work life at 70 C: 21 days
Storage life at 0 F: 12 months
Very low VOC content no added solvents during manufacture
Snap cure available for hot press moulding consult SHD for details
Storage & Out Life
This material should be kept frozen at 0 F. It must be kept sealed in a polythene bag which must not be
opened until fully thawed to room temperature. If the material is not fully used, then the material must be
resealed in the polythene bag to prevent moisture absorption.
