MR. JO JR 3016: Modified Epoxy Resin for Adhesives, Topcoats & Flooring
Introduction
Formulators striving for high performance in adhesives, flooring, or clear topcoats often face compromises: either add diluents or reactive modifiers after purchase (which introduces variability), or settle for a resin that’s simply too viscous. JR 3016 is engineered to...

MR. JO JR-3013: Low-Viscosity Modified Epoxy Resin for Tile Grouts, Primers, and Coatings
Introduction
In the formulation of primers, coatings, and tile grouts, viscosity control is one of the most critical parameters. Unmodified bisphenol-A (BPA) epoxy resins provide excellent adhesion and durability but are typically too viscous for thin-film or highly filled applications. This leads formulators to rely on...

MR. JO JR 3012: Modified Epoxy Resin for Coatings, Primers, Mortars, and Flooring
Introduction
As industries continue shifting toward high-solids, solvent-free, and environmentally compliant epoxy systems, formulators need liquid resins that offer both low viscosity and high versatility. Unmodified bisphenol-A (BPA) resins deliver excellent adhesion and durability, but their viscosity often limits solids loading and ease of processing.

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....
