## Abstract

An adhesive composition includes a first part comprising about 15 to about 60 wt % of an epoxy compound, about 35 to about 80 wt % of an epoxy novolac, and about 5 to about 25 wt % of an epoxy-based reactive diluent based on the total weight of epoxy compound, epoxy novolac, and reactive diluent; and a second part comprising less than about 20 wt % of a hydroxyaromatic solvent, about 80 to about 99 wt % of a Mannich base, and about 1 to about 20 wt % of a tertiary amine, based on the total weight of hydroxyaromatic solvent, Mannich base, and tertiary amine, the first and second parts being present in a volume ratio of about 0.8:1 to about 1.2:1. Additives to further enhance the properties may be included. A method of forming an adhesive layer includes applying the adhesive composition to a surface.

## Claims

### Claim 1

An adhesive composition comprising:
a first part comprising
about 15 to 30 wt % of a first epoxy compound,
about 30 to about 50 wt % of an epoxy novolac different from the first epoxy compound, and
about 7 to about 12 wt % of an epoxy-based reactive diluent different from the first epoxy compound and the epoxy novolac
based on the total weight of the first part; and
a second part comprising
about 1 to about 20 wt % of a hydroxyaromatic solvent,
about 80 to about 85 wt % of a Mannich base, and
about 5 to about 15 wt % of a tertiary amine,
based on the total weight of the hydroxyaromatic solvent, the Mannich base, and the tertiary amine,
the first and second parts being present in a volume ratio of about 0.8:1 to about 1.2:1;
wherein upon curing, the adhesive composition meets or exceeds all requirements of ICC-ES AC-308.

### Claim 2 (depends on 1)

The adhesive composition of claim 1, wherein the first epoxy compound is a bisphenol-based diepoxy compound including bisphenol-A epoxy, bisphenol-F epoxy, or a combination comprising at least one of the foregoing.

### Claim 3 (depends on 1)

The adhesive composition of claim 1, wherein the epoxy novolac comprises the reaction product of a phenolic compound with an aldehyde, wherein phenolic hydroxy groups of the epoxy novolac are substituted with at least one glycidyl ether group.

### Claim 4 (depends on 1)

The adhesive composition of claim 1, wherein the epoxy containing reactive diluent is a C6-30 aliphatic compound comprising two or more epoxy groups.

### Claim 5 (depends on 1)

The adhesive composition of claim 1, wherein the Mannich base is a C6-30 organic compound comprising two or more primary amine groups.

### Claim 6 (depends on 1)

The adhesive composition of claim 1, wherein the tertiary amine is a C6-30 compound comprising one or more tertiary amine groups.

### Claim 7 (depends on 1)

The adhesive composition of claim 1, wherein the first part, second part, or both the first and second parts further comprise an additive including filler, pigments, dyes, suspension agents, or a combination comprising at least one of the foregoing additives.

### Claim 8 (depends on 1)

An adhesive layer comprising the cure product of the adhesive compound of claim 1.

### Claim 9 (depends on 8)

The adhesive layer of claim 8, wherein the cure product forms after combining the first and second parts.

### Claim 10 (depends on 1)

A method of forming an adhesive layer comprising:
combining the first part and the second part of the adhesive composition of claim 1,
applying the adhesive composition to a surface.

### Claim 11

An adhesive composition comprising:
a first part comprising
about 15 to about 30 wt % of a first epoxy compound, wherein the first epoxy compound is a bisphenol-based diepoxy compound including bisphenol-A epoxy, bisphenol-F epoxy, or a combination comprising at least one of the foregoing,
about 30 to about 50 wt % of an epoxy novolac different from the first epoxy compound, wherein the epoxy novolac comprises the reaction product of a phenolic compound with an aldehyde, wherein phenolic hydroxy groups of the epoxy novolac are substituted with at least one glycidyl ether group, and
about 7 to about 12 wt % of an epoxy-based reactive diluent different from the first epoxy compound and the epoxy novolac, wherein the epoxy containing reactive diluent is a C6-30 aliphatic compound comprising two or more epoxy groups,
based on the total weight of first part; and
a second part comprising
less than about 20 wt % of a hydroxyaromatic solvent,
about 80 to about 99 wt % of a Mannich base, and
about 1 to about 20 wt % of a tertiary amine,
based on the total weight of hydroxyaromatic solvent, Mannich base, and tertiary amine, the Mannich base and the tertiary amine being present in a weight ratio of about 9:1 to about 8:1;
the first and second parts being present in a volume ratio of about 0.8:1 to about 1.2:1,
wherein upon curing, the adhesive composition meets or exceeds requirements of ICC-ES AC-308.
