JR 3000 vs JR 3001 vs JR 3003 vs JR 3125 — which unmodified epoxy resin should you use?
When engineers, formulators and shop managers pick an unmodified epoxy resin they’re solving a set of practical problems: matching viscosity to the process, getting the required optical clarity, tuning cure behavior via an appropriate hardener, and minimizing waste and handling issues on the shop floor....

MR. JO JR-3125 — Very-high-viscosity unmodified epoxy for adhesive formulators (revised)
Technical snapshot
Type: unmodified BPA epoxy resin (resin-only)
EEW: 200–250 g/eq (reactive backbone for formulators)
Viscosity: very high (formulator grade — significantly thicker than JR-3003)
Packaging: 10 / 20 / 30 kg packs and barrels; long shelf stability in company packaging
The real...

MR. JO JR 3003 — High-Viscosity Unmodified Epoxy for Adhesives & Decoupage Coatings
Technical snapshot
Type: Unmodified BPA epoxy resin (resin-only)
EEW: 200–230 g/eq
Viscosity: 20,000–40,000 mPa·s (high)
Packs: 10 / 20 / 30 kg and barrels; long shelf stability
Primary problem addressed
Many adhesive and decorative coating tasks require body — the ability to stay where applied, bridge gaps and avoid sag...

MR. JO JR-3000 — the practical, shop-ready unmodified epoxy resin
JR-3000 is an unmodified, multipurpose BPA epoxy resin with EEW 185–195 (typical 188) and viscosity 10,000–15,000 mPa·s (typical 11,800 mPa·s). It is engineered to behave like familiar industry baselines (YD128 / GY250 / KER828 / B11) while solving common...

Clear, thick epoxy adhesive made for artists — when you need a tough, glassy bond that’s easy to work with.
Clear, thick epoxy adhesive made for artists — when you need a tough, glassy bond that’s easy to work with.
If you make jewelry, glass art, small resin assemblies or decorative repairs, you know the pain: ordinary adhesives fog clear joins, run off curved edges, or...
