Test material

Reference
Name:
Unnamed
Type:
Constituent
Details on test material:
Test material were epoxyresin based products containing diamines (Isophoron diamine, m-Xylylene diamine). Typical ratio hardener : resin=1 : 3, Content of Isophorone diamine 25%-80%. Hardener contained usually up to 50% Isophorone diamine .

Concentration
Location:
construction site
Substance or metabolite:
substance
Remarks:

Applicant's summary and conclusion

Conclusions:
Under the conditions of the study, all samples taken at breathing level during mixing and working procedures were shown not to exceed 34 µg/m3 Isophorone diamine in air.
Executive summary:

Concentration of diamines in air during flooring/duct relining procedures with epoxybased resins were determined at construction sites and in a laboratory test by BG Bau.

Personally taken samples at breathing level during flooring at four construction sites, during laboratory test focused on mixing of epoxy based resin and during duct relining at five construction sites were collected and analysed regarding Isophorone diamine. All samples taken at breathing level during mixing and working procedures were shown not to exceed 34 µg/m3 Isophorone diamine in air.
