Abstract
A solvent-based polyurethane retort adhesive composition for producing laminates including: (A) at least one isocyanate compound, Component A; and (B) at least one isocyanate (NCO)-reactive component, Component B, comprising (i) at least one phosphate ester compound and (ii) at least one polyester polyol having an average molecular weight of greater than 3,000 g/mol; a process for producing the above adhesive; a multi-layer laminate product including the above adhesive; and a process for producing a laminate product using the above adhesive.
Claims17
A solvent-based retort adhesive composition comprising:
- (A) an isocyanate compound, Component A, wherein the isocyanate compound, Component A, consists of a single aliphatic-based isocyanate;
- or wherein the isocyanate compound, Component A, consists of a single aromatic-based isocyanate;
- and
- (B) an isocyanate-reactive component, Component B;
- comprising:
- (i) at least one phosphate ester compound,
- (ii) an aliphatic polyester polyol having an average molecular weight of greater than or equal to 3,000 g/mol, and
- (iii) an optional polyether polyol, wherein (B)(i), (B)(ii), and (B)(iii) amount to 100 wt % of the isocyanate-reactive component (B).
A solvent-based retort adhesive composition comprising:
- (A) an isocyanate compound, Component A, wherein the isocyanate compound, Component A, is a blend consisting of (i) a single aliphatic-based isocyanate and (ii) a single aromatic-based isocyanate;
- and
- (B) an isocyanate-reactive component, Component B;
- comprising
- (i) at least one phosphate ester compound,
- (ii) an aliphatic polyester polyol having an average molecular weight of greater than or equal to 3,000 g/mol, and
- (iii) an optional polyether polyol, wherein (B) (i), (B) (ii), and (B) (iii) amount to 100 wt % of the isocyanate-reactive component (B).
A solvent-based retort adhesive composition comprising:
- (A) an isocyanate compound, Component A, wherein the isocyanate compound, Component A, is a blend consisting of (i) a first aromatic-based isocyanate and (ii) a second aromatic-based isocyanate different than the first aromatic-based isocyanate;
- and
- (B) an isocyanate-reactive component, Component B;
- comprising:
- (i) at least one phosphate ester compound,
- (ii) an aliphatic polyester polyol having an average molecular weight of greater than or equal to 3,000 g/mol, and
- (iii) an optional polyether polyol, wherein (B) (i), (B) (ii), and (B) (iii) amount to 100 wt % of the isocyanate-reactive component (B).
