MR. JO JH 8361 – Heavy-Duty Phenalkamine Hardener for Marine & Protective Coatings

When it comes to epoxy curing in real-world conditions, very few hardeners can match the performance of phenalkamines. JH 8361 is our high-performance phenalkamine curing agent, specially designed for marine coatings, heavy-duty floorings, and protective applications where humidity, moisture, and salt contamination are everyday challenges.

MR. JO Phenalkamine Hardener Selector Guide

MR. JO Phenalkamine Hardener Selector Guide Phenalkamines are the go-to curing agents for epoxy systems exposed to tough, humid, and variable site conditions. Derived from cashew nutshell liquid (CNSL), they offer excellent adhesion, chemical resistance, and tolerance to surface moisture and salt contamination — making them...

MR. JO JH 1037: Diethylenetriamine (DETA) – The Fast-Curing Workhorse for Epoxy Systems

When formulators need very fast cure, strong adhesion, and reliable chemical resistance, Diethylenetriamine (DETA) is often the first choice. JH-1037 brings this standard curing agent to you in reliable quality and flexible pack sizes, making it accessible for both industrial scale and smaller, specialized projects.

MR. JO JH 1027: Tetraethylenepentamine (TEPA) – High Functionality Hardener for Stronger, Faster Epoxy Systems

When epoxy systems demand higher crosslink density, faster cure, and improved chemical resistance, formulators look for curing agents with more reactive sites. JH 1027 (TEPA – Tetraethylenepentamine) fits that role perfectly as a multi-functional aliphatic amine.
