SDF369AB Epoxy Resin

SDF369AB Epoxy Resin EPOXY RESINS

Product Code: SDF-EPO-027

SDF369AB Epoxy Resin: Solvent-free modified high-temperature epoxy adhesive for hand lay-up and lamination.

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 SDF369AB Epoxy Resin?
Solvent-free modified high-temperature epoxy adhesive for hand lay-up and lamination. 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 100:20 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.
