US Patent:

53709080, Dec 6, 1994

Filed:

May 24, 1993

Appl. No.:

8/065009

Inventors:

James M. O'Connor - Branford CT
Fred A. Stuber - North Haven CT
Kiran B. Chandalia - Cheshire CT
Adam G. Malofsky - Huntington CT

Assignee:

Olin Corporation - Cheshire CT

International Classification:

B05D 302

US Classification:

4273855

Abstract:

The present invention relates to a process for coating a substrate which comprises (a) contacting said substrate with a low volatility organic (so-called "low VOC") coating composition having a viscosity as measured by ZAHN cup 2 of less than about 200 seconds and consisting essentially of at least one polyisocyanate, a solvent in an amount of between 0% and 45% by weight based upon the amount of said polyisocyanate in said composition, and an trimerization catalyst, said composition being essentially free of any volatile mono- and di-isocyanates, to form a coating on said substrate, and (b) heating said coating to a curing temperature of between 120. degree. F. and 350. degree. F. for a curing time of between about ten minutes and about six hours in order to cure said coating by trimerizing at least some of the isocyanate groups of the polyisocyanate to provide a heat-cured coating on said substrate. Also claimed is the coating composition itself.

International Classification:

C08G 1865
C08G 1866
C08K 505
C08K 506

US Classification:

521137

Abstract:

A stable dispersion of a polymer in a polyol is prepared by reacting an organic polyisocyanate with a short-chain polyol in a high molecular weight polyol containing a relatively high primary hydroxyl group content, the ratio of the content of primary hydroxyl groups in the short-chain polyol to that in the high molecular weight polyol being at least a critical lower limit of about 3. 5. The reaction is further carried out in the presence of a small proportion of water to achieve a reduction in the viscosity of the resulting dispersion. The dispersion is used in preparing high resilience polyurethane foam having desirable physical properties and which is of utility in a wide variety of cushioning applications.

Olin Corporation - Cheshire CT

International Classification:

C08K 512

US Classification:

523122

Abstract:

The present invention relates, in one aspect, to a process for preparing a storage-stable dispersion of a biocide which comprises the steps of: (a) mixing a plastisol, comprising a resin and a carrier, and a biocide to provide a mixture of said plastisol and said biocide (b) heating said mixture of plastisol and biocide to an elevated temperature of between about 30. degree. C. and about 100. degree. C. to provide a homogeneous, storage stable dispersion, said dispersion containing said biocide in an amount of between about one and about 30 weight percent based upon the weight of said dispersion, said resin being present in an amount of between about 5 and about 75 weight percent based upon the weight of said dispersion, with the proviso that when the weight percent of said resin in said dispersion is between about 30% and about 75%, then said elevated temperature is between 30. degree. C. and 45. degree. C. , and when the weight percent of said resin in said dispersion is between about 5% and about 29%, then said elevated temperature is between 46. degree. C. and 100. degree. C. , and (c) cooling the dispersion to a temperature of between about -20. degree. C.

Assignee:

Olin Corporation Research Center - New Haven CT

International Classification:

C08G 1882

US Classification:

528491

Abstract:

Unreacted diisocyanate is removed from a polyurethane prepolymer reaction product mixture by co-distillation of the unreacted diisocyanate with a compound which is at least partially miscible with the prepolymer and which boils at a temperature greater than the boiling point of the diisocyanate. A highly efficient removal rate is achieved in that the concentration of unreacted diisocyanate remaining in the reaction product mixture is generally less than about 0. 1 percent, and in many cases less than about 0. 05 percent, based on the weight of the prepolymer.
