Abstract
Abstract Described is a one package adhesive stable at ambient temperature and pressure comprising; a. a liquid phase comprising a polymerizable epoxy resin in the liquid state, an organic plasticizer capable of solubilizing the epoxy resin in an amount sufficient to impart flow to the adhesive; b. a solid phase comprising a carboxy reactive polyvinyl chloride and an effective catalytic amount of the reaction product of a saturated aliphatic polyamine and a saturated aliphatic carboxylic acid or anhydride or an aromatic or cycloaliphatic acid or anhydride. The one package adhesive is capable of being stable for long periods of time without curing thereof and is useful as an adhesive for securing metallic substrates.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
90 words
A one package adhesive stable at ambient temperature and pressure consisting essentially of; a. a liquid phase consisting essentially of a polymerizable epoxy resin in the liquid state, an organic plasticizer capable of solubilizing the epoxy resin in an amount sufficient to impart flow to the adhesive; and b. a solid phase consisting essentially of a carboxy reactive polyvinyl chloride and an effective catalytic amount of the reaction product of a saturated aliphatic polyamine and a saturated aliphatic carboxylic acid or anhydride or an aromatic or cycloaliphatic acid or anhydride.
Claim 2
Dependent Claim
90 words
A one package adhesive stable at ambient temperature and pressure consisting essentially of; a. a liquid phase consisting essentially of a polymerizable epoxy resin in the liquid state, an organic plasticizer capable of solubilizing the epoxy resin in an amount sufficient to impart flow to the adhesive; and b. a solid phase consisting essentially of a carboxy reactive polyvinyl chloride and an effective catalytic amount of the reaction product of a saturated aliphatic polyamine and a saturated aliphatic carboxylic acid or anhydride or an aromatic or cycloaliphatic acid or anhydride.
Claim 3
Dependent Claim
15 words
The adhesive of claim 1 wherein the ratio of epoxy:plasticizer:PVC:curing agent ranges from about 0.5-5:0.1-3:0.5-5:0.1-3.
Claim 4
Dependent Claim
12 words
The adhesive of claim 1 wherein the plasticizer is a dialkyl phthalate.
Claim 5
Dependent Claim
16 words
The adhesive of claim 1 wherein the curing agent is a compound of the formula: ##STR3##
Claim 6
Dependent Claim
17 words
The adhesive of claim 1 wherein the epoxy is the reaction product of a bisphenol and epichlorohydrin.
Claim 7
Dependent Claim
19 words
The adhesive of claim 1 wherein the catalyst is the reaction product of phthalic anhydride and an aliphatic polyamine.
Claim 8
Dependent Claim
13 words
The adhesive of claim 1 wherein the weight ratio of (a):(b) is one.
Claim 9
Dependent Claim
45 words
A method for securing substrates to each other comprising the steps: 1. applying the composition of claim 1 to a first substrate; 2. heating the substrate to a temperature of at least 65° C., thereby liquifying the solid amine curative; and 3. curing the composition.
