MR. JO JH 8378 – Fast Reactivity with Site-Friendly Handling Every project has its own rhythm. Some demand faster turnaround, others need flexibility for applicators to work comfortably. Mr. JO Hardener 8378 has been developed to offer the best of both worlds — a phenalkamine hardener...

MR. JO JH 8362 – Reliable Curing in Cold & Damp Conditions Working on-site often means working with uncertainty — low temperatures, damp concrete, or even high humidity levels. Conventional curing agents struggle in such conditions, leading to delayed schedules and compromised performance. JH 8362 has...

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,...

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 1063 – Fast-Curing Epoxy Hardener for Quick Turnaround Applications When time is of the essence, you need an epoxy system that cures fast without compromising bond strength. JH 1063 is designed exactly for that—an unmodified amine hardener that delivers rapid cure, excellent hardness,...

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...

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...

MR. JO JH 1029: Isophorone Diamine (IPDA) – The Choice for UV-Resistant, Tough & Durable Epoxy Systems When epoxy systems are exposed to sunlight, outdoor weather, or demanding structural conditions, formulators need a curing agent that delivers UV resistance, toughness, and long-term durability. That’s where  JH...

MR. JO JH 1035: Polyetheramine Hardener for Flexible, Clear & High-Performance Epoxy Systems When strength must combine with flexibility, clarity, and toughness, formulators turn to Polyetheramines.  JH 1035 is a polyetheramine (D230 equivalent) that offers outstanding toughness, flexibility, and moisture resistance while retaining compatibility with a...

MR. JO JH 1036: The Versatile Triethylenetetramine (TETA) Hardener When it comes to curing epoxy resins, few hardeners offer the balance of reactivity, economy, and versatility like Triethylenetetramine (TETA). JH 1036 delivers exactly that — a reliable unmodified amine hardener that formulators trust across coatings, flooring,...
