Abstract
Novel organopolysiloxane compositions that are storage-stable in the absence of moisture, but curable into elastomeric state in the presence of moisture, nonetheless devoid of any organometallic curing catalyst, include (A) an .alpha.,.omega.-dihydroxydiorganopolysiloxane oil, (B) a ketiminoxysilane crosslinking agent, (C) inorganic filler material, (D) an organofunctional silane and (E) a substituted hydroxylamine; the crosslinked elastomers produced from these organopolysiloxane compositions are well adopted for such applications as foodstuff packaging, medical bandaging and antifouling/antisoiling coatings.
