Technical Guidance Information

01

Storage and Out Life

This material should be kept frozen at 0°F (-18°C). Good industry standard handling practices for epoxy prepregs dictate that it should be kept sealed in a polythene bag, which is typically opened once 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.

02

Health and Safety

This material contains epoxy resin which can cause allergic reactions with skin contact and must avoid repeated and prolonged skin contact.

Please refer to the product Safety Data Sheet before using this material. The following precautions must be taken when using epoxy resin prepregs:

  • Overalls must be worn

  • Impervious gloves must be worn

  • Curing schedule is meant to be as a guide only and is subject to local conditions

  • To avoid exotherm, particular care must be taken with thick laminates

  • Ramp rates must not exceed 5.4°F (3.0°C) /min during initial cure in autoclave and oven processes, and 0.5°F (0.3°C) /min during free standing post cure

Frequently Asked Questions

01

Is this a suitable prepreg for press moulding composite parts?

MTC580 is designed specifically for press moulding, with controlled resin flow to help produce consistent parts. It can also be processed in an oven or autoclave, giving manufacturers flexibility across different production methods. 

02

What prepreg is suitable for high-volume composite production?

MTC580 is a strong choice for faster, repeatable production. Its controlled flow and press-moulding capability make it well suited to automotive, motorsport, aerospace and sporting goods where consistent results are important. 

03

Is there a prepreg that is easy to shape around complex parts?

Yes. MTC580 has good tack and drape, meaning it sticks well during lay-up and follows complex shapes more easily. This can help when producing detailed or curved composite components. 

04

Can MTC580 be used with different fibre types?

Yes. MTC580 can be supplied on a wide range of woven fabrics and unidirectional tapes, allowing the reinforcement to be matched to the part’s strength, weight, cost and manufacturing needs. 

05

Is there a fast-curing prepreg for composite manufacturing?

Yes. Snap-curing versions of MTC580 are available for applications where shorter production cycles are important. SHD can advise on the most suitable version based on the part and manufacturing process.
