Abstract
Abstract A hardenable composition for use as an adhesive in sealing, spackling, filling, stamping and the like composed of a first component of a monomeric, oligomeric or polymeric compound and a hardening promoting agent, wherein the first component or the hardening promoting agent is encased in a protective casing to prevent rupturing of the casing or hardening of the composition, and a casing rupturing agent composed of microspheres which break under pressure into fragments which have angular edges or are acutely tapered.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
100 words
In a hardenable composition of the type composed of a mixture of a first component of a monomeric, oligomeric or polymeric compound and a hardening promoting agent wherein one or both of the first component and the hardening agent is encased in a protective casing which prevents the reaction and subsequent hardening of the composition until rupture of the casing and which further contains a casing rupturing agent, the improvement which comprises said rupturing agent being microspheres which break under the pressure applied in the normal use of the composition into fragments possessing angular edges or which are acutely tapered.
Claim 2
Dependent Claim
100 words
In a hardenable composition of the type composed of a mixture of a first component of a monomeric, oligomeric or polymeric compound and a hardening promoting agent wherein one or both of the first component and the hardening agent is encased in a protective casing which prevents the reaction and subsequent hardening of the composition until rupture of the casing and which further contains a casing rupturing agent, the improvement which comprises said rupturing agent being microspheres which break under the pressure applied in the normal use of the composition into fragments possessing angular edges or which are acutely tapered.
Claim 3
Dependent Claim
10 words
The composition of claim 1 wherein the microspheres are hollow.
Claim 4
Dependent Claim
13 words
The composition of claim 1 wherein the microspheres are composed of inorganic materials.
Claim 5
Dependent Claim
10 words
The composition of claim 3 wherein the microspheres are silicates.
Claim 6
Dependent Claim
13 words
The composition of claim 4 wherein the microspheres are composed of calcium silicate.
Claim 7
Dependent Claim
25 words
The composition of claim 1 wherein the microspheres are selected from the group consisting of hollow glass bodies, hollow ceramic bodies and hollow plastic bodies.
Claim 8
Dependent Claim
16 words
The composition of claim 1 wherein the microspheres have a diameter of less than 1,500 millimicrons.
Claim 9
Dependent Claim
19 words
The composition of claim 1 wherein the microspheres have a specific weight of less than 1.0 g/cm 3 .
Claim 10
Dependent Claim
31 words
The composition of claim 1 wherein the microspheres are present in an amount of about 1 to 600% by weight, based on the weight of the monomeric, oligomeric or polymeric compounds.
Claim 11
Dependent Claim
23 words
The composition of claim 1 wherein the individual microspheres have a volume one to three times greater than that of the protective casings.
Claim 12
Dependent Claim
35 words
The composition of claim 1 wherein the hardening promoting agent is selected from the group consisting of inorganic oxidation agents, organic oxidation agents, metal oxides, peroxy acids, peroxides, hydroperoxides, amines, imines, mercaptans and azo compounds.
Claim 13
Dependent Claim
16 words
The composition of claim 1 wherein the hardening agent has a particle size of <1500 μm.
Claim 14
Dependent Claim
10 words
The composition of claim 1 which further contains filling materials.
Claim 15
Dependent Claim
27 words
The composition of claim 1 wherein the microspheres, protective casings or filling materials are pretreated with compounds selected from the group consisting of silanes and chromium complexes.
Claim 16
Dependent Claim
29 words
The composition of claim 13 wherein the microspheres or the filling materials are treated with antichemisorption agents selected from the group consisting of fatty acids and fatty acid derivatives.
Claim 17
Independent Claim
87 words
A method for making a hardenable composition comprising admixing a first component of a monomeric, oligomeric or polymeric compound, a second component of a hardening promoting agent said first or said second component being encased in a protective casing which prevents the reaction and subsequent hardening of the composition until rupture of the casing and a third component of a rupturing agent composed of microspheres which break under the pressure applied in the normal use of the composition into fragments possessing angular edges which are acutely tapered.
Claim 18
Independent Claim
87 words
A method for making a hardenable composition comprising admixing a first component of a monomeric, oligomeric or polymeric compound, a second component of a hardening promoting agent said first or said second component being encased in a protective casing which prevents the reaction and subsequent hardening of the composition until rupture of the casing and a third component of a rupturing agent composed of microspheres which break under the pressure applied in the normal use of the composition into fragments possessing angular edges which are acutely tapered.
