H317: May cause an allergic skin reaction. H318: Causes serious eye damage. H412: Harmful to aqua tic life with long lasting effects. Precautionary Statement(s) P101: If medical advice is needed, have product container or label at hand. P102: Keep out of reach of children. P26 1 : Avoid breathing vapours.

Note Gorilla Epoxy contains 2,2,4(or 2,4,4) - trimethylhexane - 1,6 - diamine CAS No. 25513 - 64 - 8 which, according to Annex 1, Table 3.2.3 of CLP carries the H314: corrosive classification. Product level dermal corrosivity testing for Gorilla Epoxy confirms the product is classified as a skin irritant rather than corrosive. Positive results in a valid and acc epted skin corrosion test (Corrositex test) classifies the mixture as Non - corrosive utilizing multiple replicate samples indicating highly reproducible results. As a result, the health hazard and transport classification have been changed to reflect the Ep oxy results: UN Non - Corrosive and not a GHS Category 1.
