Abstract
Official abstract text for this publication.
Accelerator solution suitable for forming a redox system with peroxides, comprising a Cu(I) compound, a transition metal selected from cobalt and titanium, a phosphorous-containing compound, a nitrogen-containing base, and a hydroxy-functional solvent.
First claim
Opening claim text (preview).
The invention claimed is: 1. Accelerator solution suitable for forming a redox system with peroxides, comprising a Cu(I) compound, a titanium salt or complex, a phosphorous-containing compound, a nitrogen-containing base, and a hydroxy-functional solvent wherein the weight ratio, based on metal weight, of the Cu(I) compound to the titanium salt or complex is in the range of 3:1 to 200:1. 2. Accelerator solution according to claim 1 wherein the phosphorous-containing compound is a dialkyl phosphate. 3. Accelerator solution according to claim 1 further comprising an alkali or alkaline earth metal compound and/or a 1,3-diketone. 4. Pre-accelerated resin composition comprising a curable resin, a Cu(I) compound, a titanium salt or complex, a phosphorous-containing compound, a nitrogen-containing base, and a hydroxy-functional solvent wherein the weight ratio, based on metal weight, of the Cu(I) compound to the titanium salt or complex is in the range of 3:1 to 200:1. 5. Pre-accelerated resin composition according to claim 4 wherein the phosphorous-containing compound is a dialkyl phosphate. 6. Pre-accelerated resin composition according to claim 4 further comprising an alkali or alkaline earth metal compound and/or a 1,3-diketone. 7. Two-component composition comprising a first component and a second component, the first component comprising the pre-accelerated resin composition according to claim 4 , the second component comprising a peroxide. 8. Two component composition according to claim 7 wherein the peroxide is selected from the group consisting of organic hydroperoxides, ketone peroxides, peroxycarbonates, and peroxyesters.
