New curing agent for benzyl alcohol-free epoxy primers: MEEDamine® 2444 S zero
Since years, SRS-MEEDER has a polyaminoamide-based epoxy hardener MEEDamine® 2450 S in its portfolio, which imparts unique properties to various coating applications, especially excellent adhesion. Over the time this hardener type has proven very successful in primers on mineral and critical substrates, e.g. contaminated or moist concrete as well as in high-solid-coatings on metals.
Moreover, SRS-MEEDER offers MEEDamine® 2444 S, a modification which is free from SVHC-substances like alkyl phenols.
Consequently, we now take the next step and launch MEEDamine® 2444 S zero: a further development, which, being chemically analogous to MEEDamine® 2444 S, additionally is completely free from benzyl alcohol. Thus, we offer to users the possibility to formulate emission-free primers and other coatings, which are compliant with German AgBB-guidelines or comparable regulations in other countries. Respective emission-free coatings are required e.g. for sensible common rooms like in hospitals, kindergartens etc. Due to the substitution of benzyl alcohol in MEEDamine® 2444 S zero it yields higher glass transition temperatures after curing und thus improved mechanical properties. Potential fields of application are the same as with MEEDamine® 2450 S or MEEDamine® 2444 S.
MEEDamine® 2444 S zero complements our already existing portfolio of modern epoxy hardeners free from alkyl phenols and benzyl-alcohol*:
MEEDamine® 2100: special polyamine polycondensate hardener for top-coats
MEEDamine® 2633 S: special polyamine polycondensate hardener for top-coats
MEEDamine® 2644: special adduct hardener for top-coats
MEEDamine® 2462 S: low-viscous fast curing hardener for low-temperature applications
MEEDamine® 2761: special adduct hardener for flexible coatings
These epoxy curatives enable the formulation of coatings for various application profiles, which are completely free from alkyl phenols and benzyl alcohol.
A Technical Information Leaflet of our new MEEDamine® 2444 S zero is attached to this newsletter.
