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-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...
