MR. JO JR 3005L: Low-Viscosity Modified Epoxy Resin for Flowable Systems

Introduction

When it comes to self-levelling floorings, flowable mortars, and construction adhesives, formulators face the constant challenge of achieving the right balance between workability and performance. Standard bisphenol-A epoxy resins are often too viscous for these applications, requiring external reactive diluents to improve flow. However,...

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....
