English to Italian Tech/Engineering Chemistry; Chem Sci/Eng Caratteristiche prodotti antigraffiti

Non mi viene come renderlo in italiano pur avendo afferrato il senso.
Non credo sia né "condizioni limite" né "condizioni ai limiti" qui. Grazie per ogni suggerimento dato.

A number of commercial anti-graffiti products for outdoor applications have been developed over the
years, which are distinguished by their mode of action (permanent, sacrificial semi-permanent) as well by
their key ingredients (e.g. wax, latex, polymer resins). Besides other ***boundary conditions*** such as the
local climate, the suitability of a given anti-graffiti coating is directly correlated to the material onto which it
is to be applied (metal, glass, plastics, concrete, stone, plaster, ...) as well as the morphology and
characteristics of said substrate (in terms of smoothness, porosity, natural water uptake, ...).
