Abstract
Abstract Composition for coating, filling, binding and protection, comprising rubber, whereby it comprises rubber having a particle size of at most 0.4 mm present in an amount of 20-50% by weight, and a curable polymer base present in an amount of 40-50% by weight, which components after curing of said polymer base are the elastic and adhesive part of the composition. The invention further relates to a process for preparation, and a process for applying said composition.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
48 words
A process for preparation of a composition for coating, filling, binding, and protection, which comprises mixing rubber powder having a particle size of at most 0.4mm with an isocyanate curable polyurethane, and an aliphatic polyether glycol; and subjecting the mixture to a vacuum of at least 0.9 bar.
Claim 2
Dependent Claim
48 words
A process for preparation of a composition for coating, filling, binding, and protection, which comprises mixing rubber powder having a particle size of at most 0.4mm with an isocyanate curable polyurethane, and an aliphatic polyether glycol; and subjecting the mixture to a vacuum of at least 0.9 bar.
Claim 3
Dependent Claim
18 words
The process according to claim 1, wherein the subpressure is 0.8 bar, but not lower than 0.5 bar.
Claim 4
Dependent Claim
16 words
The process according to claim 1, wherein the rubber has a particle size of 0.01-0.2 mm.
Claim 5
Dependent Claim
33 words
The process according to claim 1, wherein the composition further comprises an ingredient selected from the group consisting of a zeolitic drying agent, an active aluminum oxide, an aluminum silicate and mixtures thereof.
Claim 6
Dependent Claim
15 words
A process according to claim 1 wherein the rubber powder further includes a coloring pigment.
Claim 7
Dependent Claim
56 words
The process according to claim 1, wherein the composition comprises: 4 to 55% by weight of an isocyanate curable polyurethane; 20 to 50% by weight of a rubber having a particle size of at most 0.4 mm; 18 to 30% by weight of a polymer curing isocyanate; and 1 to 5% of an aliphatic polyether glycol.
Claim 8
Dependent Claim
101 words
A process for applying a composition for coating, filling, binding, and protection prepared according to the process of claim 1, by means of high pressure, which comprises drawing the composition into a modified twocomponent high pressure pump together with a hardener; placing a pressure plate on the high pressure pump; pressing the pressure plate down into the composition in order to press the composition up into the pump; and heating the composition to greater than 40° C. in connection with said pump, such that a spray of finely dispersed composition having a pressure of 150 kg/cm 2 or more is obtained.
Claim 9
Dependent Claim
59 words
The process according to claim 7, wherein the composition comprises: 4 to 55% by weight of an isocyanate curable polyurethane; 20 to 50% by weight of a rubber having a particle size of at most 0.4 mm; 1to 5% of an aliphatic polyether glycol; and wherein the hardener comprises 18 to 30% by weight of a polymer curing isocyanate.
