Abstract

Isocyanate-reactive compositions, rigid polyurethane foam-forming compositions, rigid polyurethane foams, and methods for their production, and composite articles having a rigid polyurethane foam sandwiched between metal facer substrates. The rigid polyurethane foams are produced from an isocyanate-reactive composition comprising: (1) a polyol blend that includes an amine-initiated polyether polyol; (2) a hydrochlorofluoroolefin ('HCFO'); and (3) a catalyst that includes an arylalkyl tertiary amine, an aryl tertiary amine, or a mixture thereof. The foam can have excellent adhesion to metal substrates.
