EPOXY RESINS

Product Code: SDF-EPO-028

SDF5050AB-1 Epoxy Resin: Flowable black epoxy system for electronic-component potting and moisture protection.

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 SDF5050AB-1 Epoxy Resin?

Flowable black epoxy system for electronic-component potting and moisture protection. 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.
