Abstract
Aromatic mono-, di-, or trihydroxy compounds are used alone or containing peel strength-improving additives, in association with a polyurethane adhesive, for adhering a polyurethane-coated nylon fabric to another polyurethane-coated nylon fabric to form a polyurethane-coated nylon composite, and for adhering a nylon fabric coated with an aluminum flake-containing polyurethane to a polyurethane-coated nylon fabric. Additionally, aromatic mono-, di-, or trihydroxy compounds are utilized in association with a polyurethane adhesive for forming a lamina composition comprising a polyurethane film adhered to a nylon fabric.
Claims55
A precoat composition comprising:
- a compound AR(OH).sub.n, wherein AR is an aromatic moiety and n is an integer of from about 1 to about 3;
- a peel strength-improving additive;
- and
- a polar solvent, so that upon application of said precoat composition to at least one of first and second polyurethane-coated surfaces of a nylon fabric to be brought into contact, and subsequent application of a formaldehyde-free polyurethane adhesive to said surfaces, adhesion between said coated nylon surfaces is improved.

An adhesive admixture composition, comprising:
- a compound AR(OH).sub.n, wherein AR is an aromatic moiety and n is an integer of from about 1 to about 3;
- a peel strength-improving additive;
- and
- a formaldehyde-free polyurethane adhesive, wherein said admixture improves adhesion between first and second polyurethane-coated nylon fabric surfaces when said surfaces are brought into contact.
1 more element
An adhesive admixture composition, comprising:
- a compound AR(OH).sub.n, wherein AR is an aromatic moiety and n is an integer of from about 1 to about 3;
- and
- a formaldehyde-free polyurethane adhesive, wherein said admixture improves adhesion between two polyurethane-coated nylon fabrics, or an aluminum-filled polyurethane-coated nylon fabric and a polyurethane-coated nylon fabric.
An adhesive admixture composition, comprising:
- a compound AR(OH).sub.n in a polar solvent to precoat polyurethane-coated nylon fabrics or an aluminum filled polyurethane-coated nylon fabric, wherein AR is an aromatic moiety;
- and
- a formaldehyde-free polyurethane adhesive, wherein said admixture improves adhesion between two polyurethane-coated nylon fabrics, or an aluminum filled polyurethane-coated nylon fabric and a polyurethane-coated nylon fabric.
A precoat composition comprising:
- a compound AR(OH).sub.n, wherein AR is an aromatic moiety and n is an integer of from about 1 to about 3;
- and
- a polar solvent, so that upon application of said precoat composition to at least one of first and second polyurethane-coated surfaces of a nylon fabric to be brought into contact, or to at least one of the surfaces of an aluminum-filled polyurethane-coated nylon fabric and a polyurethane-coated nylon fabric to be brought into contact, and subsequent application of formaldehyde-free polyurethane adhesive to said surfaces, adhesion between said coated nylon surfaces is improved.
A lamina composition, comprising:
- a) at least two layers wherein at least one layer of nylon fabric is bonded by a formaldehyde-free adhesive layer to at least one layer of a polyurethane film, or
- b) one lamina of (a) is bonded to another lamina of (a) through surfaces of the polyurethane films, or
- c) one lamina of (a) is bonded to another lamina of (a) through surfaces of the nylon fabrics,
- wherein one side of one layer has applied thereon an AR(OH).sub.n precoat, wherein AR is a benzene or naphthalene nucleus and n is an integer of from 1 to about 3, wherein said adhesive layer is a polyurethane adhesive, and
- wherein said lamina composition has a peel strength improvement of at least about 10 percent.

A lamina composition, comprising:
- a) at least two layers wherein at least one layer of nylon fabric is bonded by a formaldehyde-free adhesive layer to at least one layer of a polyurethane film, or
- b) one lamina of (a) is bonded to another lamina of (a) through surfaces of the polyurethane films, or
- c) one lamina of (a) is bonded to another lamina of (a) through surfaces of the nylon fabrics,
- wherein one side of one layer has applied thereon an AR(OH).sub.n precoat, wherein AR is a benzene or naphthalene nucleus and n is an integer of from 1 to about 3, wherein said adhesive layer is a polyurethane adhesive containing from about 5 percent to about 25 percent by weight AR(OH).sub.n,
- wherein said lamina composition has a peel strength improvement of at least about 10 percent.
2 more elements
A lamina composition comprising:
- a) at least two layers wherein at least one layer of nylon fabric is bonded by a formaldehyde-free adhesive layer to at least one layer of a polyurethane film, or
- b) one lamina of (a) is bonded to another lamina of (a) through surfaces of the polyurethane films, or
- c) one lamina of (a) is bonded to another lamina of (a) through surfaces of the nylon fabrics,
- wherein one side of one layer has applied thereon an AR(OH).sub.n precoat wherein AR is an aromatic moiety and n is an integer of from about 1 to about 3, wherein said adhesive layer is a formaldehyde-free polyurethane adhesive containing AR(OH).sub.n, and wherein said lamina composition has a peel strength improvement of at least about 10 percent.
