Diglycidylether of bisphenol A resin is the most important sensitizer in epoxy systems, but a minority of patients develop concomitant or solitary contact allergy to epoxy hardeners. At the Finnish Institute of Occupational Health, several in‐house test substances of epoxy hardeners have been tested in a special epoxy compound patch test series. 
Contact allergy to reactive diluents and related aliphatic epoxy resins
Diglycidyl ether of bisphenol A resin (DGEBA‐R) is the most common sensitizer in epoxy systems, but a minority of patients also develop contact allergy to reactive diluents.
Occupational contact allergy to the epoxy resin hardener 2‐methylpentane‐1,5‐diamine
TLDR
This case report describes the development and clinical trials of 2-methylpentane-1,5-diamine as well as contact allergy in relation to epoxy-like properties and the use of resin as a hardener in humans.
Sensitization to reactive diluents and hardeners in epoxy resin systems. IVDK data 2002–2011. Part II: concomitant reactions
TLDR
Reactive diluents and hardeners are important sensitizers in epoxy resin systems (ERSs) because of chemical similarities, immunological cross‐reactivity may occur.
Occupational contact dermatitis caused by 1,3‐benzenedimethanamine, N‐(2‐phenylethyl) derivatives in hardeners for epoxy paints and coatings
Amines in epoxy hardeners are significant causes of occupational allergic contact dermatitis among workers who use epoxy resin systems.
Sensitization to reactive diluents and hardeners in epoxy resin systems. IVDK data 2002–2011. Part I: reaction frequencies
TLDR
In order to develop less sensitizing ERS formulations, knowledge of the sensitizing properties of single components is mandatory.
Occupational allergic contact dermatitis caused by epoxy chemicals: occupations, sensitizing products, and diagnosis
TLDR
Diglycidyl ether of bisphenol A resin (DGEBA‐R) is the most important sensitizer in epoxy systems.
Allergic contact dermatitis caused by triethylenetetramine: the glue is the clue
A 51-year-old woman consulted because of suspected allergic contact dermatitis, recurring over the last 17 years. The patient had been working in an abrasive fibre production factory for the last 20

Skin exposure to epoxy chemicals in construction coating, assessed by observation, interviews, and measurements
TLDR
Epoxy resin systems (ERSs) are among the leading causes of occupational allergic contact dermatitis and need to be addressed to protect against future outbreaks.
Unrecognized leather sofa dermatitis complicating chronic plaque psoriasis
TLDR
This research presents a case study of contact dermatitis caused by epoxy chemicals in a construction site, which highlights the need to understand more fully the role of epoxy resin in the human immune system.

Contact allergy to epoxy resins–a 10‐year study
TLDR
Epoxy resins, widely used as adhesives or coatings in construction, boat and aeroplane building, plastic and other industries and trades, are a frequent cause of occupational allergic contact dermatitis but sensitization can also develop to other components, including the hardeners and reactive diluents.
Screening occupational contact allergy to bisphenol F epoxy resin
Epoxy resins based on diglycidyl ether of bisphenol F (DGEBF) are widely used as such in applications requiring chemical resistance, and also together with diglycidyl ether of bisphenol A resin
182 patients with occupational allergic epoxy contact dermatitis over 22 years
TLDR
Keywords: cycloaliphatic epoxy resin, dipropylenetriamine, methylhexahydrophthalic anhydride, polyamine hardeners, reactive diluents, tetraglycidyl-4,4′-methylene dianiline, triglycids-4-aminophenol, occupational.
Occupational airborne allergic contact dermatitis in a concrete repair worker
TLDR
By patch testing with the available epoxy resin series only, allergens responsible in the individual case might be missed and potentially allergenic components ofEpoxy resin systems are commercially available as a patch test substance.
OCCUPATIONAL ALLERGIC CONTACT DERMATITIS CAUSED BY 2,4,6‐TRIS‐(DIMETHYLAMINOMETHYL)PHENOL, AND REVIEW OF SENSITIZING EPOXY RESIN HARDENERS
TLDR
A large number of sensitizing chemicals such as epoxy resins (ER), hardeners (curing agents), and reactive diluents are found in ERCS, which is often occupational.
Airborne allergic contact dermatitis in a parquet fitter
TLDR
A case of severe airborne allergic contact dermatitis in a parquet fitter is reported and individual patch testing is essential for effective treatment.
Occupational contact allergy to monomeric isocyanates
Background. The monomeric isocyanates diphenylmethane diisocyanate (MDI), 2,4‐toluene diisocyanate (TDI), isophorone diisocyanate (IPDI) and 1,6‐hexamethylene diisocyanate (HDI) are used in
Concomitant contact allergy to the resins, reactive diluents and hardener of a bisphenol A/F‐based epoxy resin in subway construction workers
TLDR
An outbreak of suspected contact dermatitis among subway construction workers was suspected to be due to a new bisphenol A/F‐based epoxy resin system (ERS), and patch testing for reaction to all components was performed.
An attempt to improve diagnostics of contact allergy due to epoxy resin systems. First results of the multicentre study EPOX 2002
TLDR
Patients with suspected contact allergy due to ERSs and patients with a prior positive patch test reaction to epoxy resin (ER) in the standard series were patch tested, with agreement between positive reactions to 1,6‐HDDGE and 1,4‐BDDGE was even better than with the 2 resins, but the sample size is considered too small to decide reliably whether 1, 6‐ HDDGE alone could serve as a marker allergen for both.
Occupational dermatoses from exposure to epoxy resin compounds in a ski factory
TLDR
Immediate transfer of workers sensitized to epoxy resin from epoxy exposure prevents aggravation of their dermatitis and broadening of the sensitization toEpoxy hardeners, diluents and other compounds.
