Kohesi Bond manufactures a full range of chemical-resistant epoxy adhesives that maintain structural integrity and bond strength when exposed to the most aggressive chemical environments. Our extensive range spans everything from concentrated acids and solvents to sterilisation media and prolonged moisture immersion.
Discover our comprehensive range of custom-formulated epoxy adhesives designed for superior chemical resistance and performance in demanding industrial environments. For advanced chemical-resistant bonding solutions, explore our product line below.
Our chemical-resistant formulations use aromatic and cycloaliphatic resin systems combined with high crosslink density to create an adhesive matrix that resists chemical penetration, swelling, and plasticisation.
Our chemical-resistant adhesive systems are used in oil and gas, chemical processing, medical sterilisation, pharmaceutical and marine environments, and food and beverage processing equipment in non-food-contact locations. For food-contact applications requiring FDA 21 CFR compliance, contact our technical team to confirm applicable grades.
Our complete chemical-resistant epoxy resin portfolio covers acid, base, alcohol, solvent, fuel, sterilisation, and moisture resistance from a single product family. Streamline your vendor qualification process instead of auditing a different supplier for every chemical exposure type.
Chemical immersion performance is verified through rigorous testing to ASTM D543 and ISO 175, with complete data packages available upon request. Your engineering team receives certified chemical compatibility metrics rather than vague marketing claims.
Tell us the specific chemical mixtures, exact concentration percentages, and operating temperature profiles your bond line will encounter. Our R&D team adjusts crosslink density and resin chemistry around that precise exposure profile rather than recommending a generic standard grade.
Formulated in low viscosity potting compounds, thixotropic structural pastes, and thin-film chemical-resistant coatings. This allows you to apply the same validated, highly crosslinked chemistry regardless of whether your assembly process requires potting, structural bonding, or surface lining.

Access comprehensive technical documentation and expert support to ensure optimal performance in your chemical-resistant bonding applications.
Each application below covers a specific chemical resistance type with full technical guidance. Select the resistance property most relevant to your application environment.
Formulated to resist hydrochloric, nitric, sulphuric and phosphoric acid exposure, including grades validated as a hydrochloric acid-resistant sealant for tank lining and piping. We engineer each acid-resistant adhesive for continuous immersion rather than mere splash contact, verified against long-term chemical resistance testing.
Formulated to resist potassium hydroxide, sodium hydroxide and other alkaline media that attack many industrial coatings. Our systems provide a reliable corrosion-resistant adhesive and chemical-resistant sealant solution for metal equipment exposed to severe caustic environments.
Formulated to resist methanol, ethanol, butanol and isopropanol. Common in pharmaceutical, lab and cleanroom equipment specified with a methanol-resistant epoxy or an ethanol-resistant epoxy, where solvent wipe-down is part of the standard cleaning protocol. Also available as an alcohol-resistant glue for device assembly.
Formulated to resist acetone, toluene, methyl ethyl ketone (MEK), carbon tetrachloride and heptane; validated as an acetone-resistant glue and solvent-resistant adhesive for lab, cleanroom and processing equipment. A solvent-resistant epoxy with high crosslink density earns its place here over a general-purpose formulation.
Formulated to resist JP4 and JP10 jet fuels, gasoline and gasohol blends, including chemical-resistant seals for fuel line and tank connections. They’re commonly used in aviation, marine and automotive assemblies where hydrocarbon exposure is routine.
Formulated to resist ethylene oxide, hydrogen peroxide, peracetic acid and glutaraldehyde-based sterilants. Steam autoclave resistance at 121°C and 134°C applies to grades with Tg above 140°C. Gamma radiation resistance is validated for select grades at defined dose levels. Select formulations pass USP Class VI and ISO 10993-5 cytotoxicity testing; test documentation available upon request.
Formulated to resist water, humidity, salt water and steam, with select grades validated through extended 85/85 humidity testing (85°C at 85% relative humidity).

We test to ASTM D543 and ISO 175, immersing a cured sample in the specified reagent at a defined temperature for a set duration. We then measure weight change, dimensional change, and retention of hardness or mechanical strength against the unexposed baseline. A resin that passes on weight change alone but loses significant strength has still failed the practical test, which is why we report strength retention, not just mass uptake.
There isn’t a single best chemistry across every reagent. Aromatic and cycloaliphatic resin systems with high crosslink density resist chemical penetration, swelling and plasticisation broadly, and that’s our default for most chemical-resistant epoxy resin formulations. Aggressive chlorinated solvents such as carbon tetrachloride can still swell a network that handles acids and alcohols comfortably.
Usually, yes, within limits. Most grades cover acids, alcohols and fuels simultaneously, since high crosslink density resists swelling across several chemical classes at once. Chlorinated solvents and high-concentration polar reagents can exceed that shared resistance envelope and require grade-specific immersion data
Yes, and it’s one of the most commonly overlooked variables in a resistance spec. Chemical attack accelerates with temperature, since heat increases both the rate of diffusion into the resin and the rate of reaction between the chemical and the polymer network. We test and report resistance data at the temperature your application actually runs at.
Yes. Our chemical-resistant formulations are available in structural adhesive, potting compound and coating viscosities. The same validated resistance profile carries through, however your process applies it, whether dispensed as a structural bond line, cast as a potting compound, or applied as a protective coating.
Yes. If your reagent, concentration, temperature or exposure duration falls outside our published data, our technical team can run a custom immersion test against your exact profile. You’ll get the resulting weight change, dimensional change and strength retention data before you specify.
