Claims
- 1. A free-radical curable composition which is washable and self-emulsifiable upon mixing with water comprising:(a) a curable glycerol composition having the formula: wherein R1 is a C1 to C5 alkylene; R2 and R3 are independently selected from the group consisting of hydroxyl, (meth)acrylate and combinations thereof; q, s and t are independently from about 0 to about 35; provided that at least one of said R2 is said (meth)acrylate; at least one q, s or t, is not zero and that at least one of said R1 is ethyl or propyl; and(b) a free radical initiator to initiate cure of said composition, wherein said free radical initiator includes a heat-curing initiator to produce free radicals by thermal decomposition to cure said sealant.
- 2. The composition of claim 1 wherein the heat-curing initiator is selected from the group consisting of a peroxide, a hydroperoxide, a perester, an azonitrile and combinations thereof.
- 3. A free-radical curable composition which is washable and self-emulsifiable upon mixing with water comprising:(a) a curable glycerol composition having the formula: wherein R1 is a C1 to C5 alkylene; R2 and R3 are independently selected from the group consisting of hydroxyl, (meth)acrylate and combinations thereof; q, s and t are independently from about 0 to about 35; provided that at least one of said R2 is said (meth)acrylate; at least one q, s or t, is not zero and that at least one of said R1 is ethyl or propyl; and(b) a free radical initiator to initiate cure of said composition, wherein said free radical initiator includes an anaerobic-curing initiator to produce free radicals upon the exclusion of oxygen to cure said sealant.
- 4. The composition of claim 3 wherein said anaerobic-curing initiator is a peroxy initiator selected from the group consisting of hydroperoxides, peroxides, peresters and combinations thereof.
- 5. The composition of claim 3 wherein said anaerobic-curing initiator includes an anaerobic accelerator selected from the group consisting of tributyl amine, benzoic sulfimide, formamide, copper octanoate and combinations thereof.
- 6. The composition of claim 1 further including a poly(meth)acrylate ester having the formula: wherein R10 represents a radical selected from the group consisting of hydrogen, lower alkyl of from 1 to about 4 carbon atoms, hydroxyalkyl of from 1 to about 4 carbon atoms and R9 is a radical selected from the group consisting of hydrogen, halogen, and lower alkyl of from 1 to about 4 carbon atoms; R11 is a radical selected from the group consisting of hydrogen, hydroxyl and m is 0 to about 12, n is equal to at least 1, k is 1 to about 4 and p is 0 or 1.
- 7. The composition of claim 1 further including a monofunctional acrylate ester, said monofunctional acrylate ester being selected from the group consisting of lauryl methacrylate, cyclohexylmetharylate, tetrahydrofurfuryl methacrylate, hydroxyethyl acrylate, hydroxypropyl methacrylate, t-butylaminoethyl methacrylate, cyanoethylacrylate, chloroethylmethacrylate and combinations thereof.
- 8. The composition of claim 1 further including an ionic surfactant, an anionic surfactant and combinations thereof.
- 9. The composition of claim 1 wherein R1 is ethyl, propyl or a combination thereof.
- 10. A method of anaerobically or thermally sealing a porous article comprising:(a) selecting a curable glycerol composition having the formula: wherein R1 is a C1 to C5 alkyl or combinations thereof; R2 and R3 are independently selected from the group consisting of hydroxyl, (meth)acrylate and combinations thereof; q, s and t are independently from about 0 to about 35; provided that at least one of said R2 is said (meth)acrylate; at least one q, s or t, is not zero and that at least one of said R1 is ethyl or propyl; and(b) selecting a free radical initiation to initiate curing of said curable glycerol; (c) impregnating pores of said article with said curable glycerol and said initiator, and (d) washingsaid curable glycerol from a surface of said article in a wash tank containing an aqueous solution.
- 11. The composition of claim 3 further including a poly(meth)acrylate ester having the formula: wherein R10 represents a radical selected from the group consisting of hydrogen, lower alkyl of from 1 to about 4 carbon atoms, hydroxyalkyl of from 1 to about 4 carbon atoms and R9 is a radical selected from the group consisting of hydrogen, halogen, and lower alkyl of from 1 to about 4 carbon atoms; R11 is a radical selected from the group consisting of hydrogen, hydroxyl and m is 0 to about 12, n is equal to at least 1, k is 1 to about 4 and p is 0 or 1.
- 12. The composition of claim 3 further including a monofunctional acrylate ester, said monofunctional acrylate ester being selected from the group consisting of lauryl methacrylate, cyclohexylmetharylate, tetrahydrofurfuryl methacrylate, hydroxyethyl acrylate, hydroxypropyl methacrylate, t-butylaminoethyl methacrylate, cyanoethylacrylate, chloroethylmethacrylate and combinations thereof.
- 13. The composition of claim 3 further including an ionic surfactant, an anionic surfactant and combinations thereof.
- 14. The composition of claim 3 wherein R1 is ethyl, propyl or a combination thereof.
