SDF168AB-3 Epoxy Resin

SDF168AB-3 Epoxy Resin EPOXY RESINS

Product Code: SDF-EPO-024

SDF168AB-3 Epoxy Resin: Modified two-component epoxy system for filament winding and RTM.

Why does it matter?

Epoxy selection must consider viscosity, pot life, mix ratio, exotherm, cure cycle and Tg as well as final strength. A TDS mix ratio specified by weight must not be measured by volume.

Application checklist

  • Store components in dry, clean conditions.
  • Weigh A and B accurately and mix homogeneously.
  • Control pot life and exotherm for the part mass.
  • Record cure temperature and time.
  • Trial a sample panel/part before serial production.

Compare alternatives in the resin selection guide.

Frequently Asked Questions

Which application suits SDF168AB-3 Epoxy Resin?
Modified two-component epoxy system for filament winding and RTM. Final suitability must be verified for resin/hardener system, part geometry, temperature and production trials.
What is most critical in mixing and curing?
The A:B ratio is 100:80 by weight. Weigh accurately, mix homogeneously and follow the time/temperature cycle in the TDS.
Is a trial required before serial production?
Yes. TDS values are typical laboratory data. Mass effect, exotherm, humidity, tooling and reinforcement/core compatibility must be validated by a small-scale trial.
