Rheology Control For Adhesives Based On Formaldehyde Resins

US Patent:
2006005, Mar 16, 2006
Filed:
Jul 2, 2003
Appl. No.:
10/518875
Inventors:
John Manka - Chagrin Falls OH, US
Todd Yonker - Chagrin Falls OH, US
John Perz - Mentor OH, US
International Classification:
C09B 67/00
US Classification:
524502000
Abstract:
Water soluble polymers are incorporated into cellulose adhesives comprising phenol formaldehyde and related formaldehyde resins to impart more resistance to sagging and to increase the open time of the adhesive. A preferred use of the modified adhesive is as an adhesive for assembling engineered wood products such as strand board, particle board, medium density fiberboard, plywood and engineered products such as I-beams. The water soluble polymers achieve the objectives of increased sag resistance and more open time by increasing the viscosity of the adhesive and slowing the loss of water to the cellulose products and the air during use of the adhesive.

Two-Component Urethane Coating System

US Patent:
4436855, Mar 13, 1984
Filed:
Jun 29, 1983
Appl. No.:
6/508992
Inventors:
William A. Higgins - Gates Mills OH
John S. Perz - Mentor OH
Assignee:
The Lubrizol Corporation - Wickliffe OH
International Classification:
C08K 552
US Classification:
524145
Abstract:
The present invention contemplates the provision of two-component urethane coating compositions comprising a first component comprising an organic polyfunctional isocyanate, and a second component comprising an acidic ester of a phosphoric acid, the alcohol portions of said acidic acid being selected from the group consisting of hydrocarbyloxy and hydroxy-substituted hydrocarbyloxy compounds, such compositions providing enhanced corrosion resistance properties as well as improved flame retardency and metal adhesion characteristics over the two-component urethane systems of the prior art. An essential ingredient in the compositions of the invention is a non-Newtonian colloidal disperse system which can be provided with either the first component and/or the second component parts of the compositions of the invention. The non-Newtonian colloidal disperse systems provided in accordance with the present invention comprise (1) solid metal-containing colloidal particles predispersed in (2) a disperse medium of at least one inert organic liquid and (3) as an essential third component at least one member selected from the class consisting of organic compounds which are substantially soluble in said disperse medium, the molecules of said organic compound being characterized by polar substituents and hydrophobic portions. The invention also relates to a method of coating a substrate comprising mixing the foregoing components and depositing the resulting composition on said substrate.

Curable Aminoplast Compositions And Catalysts For Curing Same

US Patent:
5115083, May 19, 1992
Filed:
Apr 15, 1991
Appl. No.:
7/686058
Inventors:
Carlos A. Piedrahita - Mentor OH
Robert E. Quinn - Cleveland OH
John S. Perz - Mentor OH
Assignee:
The Lubrizol Corporation - Wickliffe OH
International Classification:
C08L 6128
US Classification:
528230
Abstract:
The present invention relates to a curable composition comprising: (A) at least one aminoplast resin; and (B) an amount effective to cure the composition of at least one catalyst selected from the group consisting of (B-1) an acid, or an anhydride, ester, ammonium salt or metal salt of the acid that is represented by one of the formulae ##STR1## (B-2) an acid, or an ester, a metal salt or ammonium salt of a sulfo compound represented by the formula: ##STR2## (B-3) an acid, or an ammonium or metal salts of a reaction product prepared by the reaction of at least one amine and sulfo compound of (B-2); and mixtures thereof; where in Formulae I and II each R. sub. 1 and R. sub. 2 is independently a hydrocarbyl, hydrocarbyloxy or hydrocaryltho group; where in Formulae I, II and III X. sub. 1 and X. sub. 2 are each independently sulfur or oxygen; R. sub.

US Patent:
4443577, Apr 17, 1984
Filed:
May 12, 1982
Appl. No.:
6/376822
Inventors:
William A. Higgins - Gates Mills OH
John S. Perz - Mentor OH
Assignee:
The Lubrizol Corporation - Wickliffe OH
International Classification:
C08K 310
US Classification:
524590
Abstract:
A composition comprising: (A) a non-Newtonian colloidal disperse system comprising (1) solid metal-containing colloidal particles predispersed in (2) a disperse medium of at least one inert organic liquid and (3) as an essential third component at least one member selected from the class consisting of organic compounds which are substantially soluble in said disperse medium, the molecules of said organic compound being characterized by polar substituents and hydrophobic portions; and (B) an isocyanate-terminated prepolymer.

Method For Curing Concrete

US Patent:
4297399, Oct 27, 1981
Filed:
Jan 8, 1980
Appl. No.:
6/110294
Inventors:
John S. Perz - Mentor OH
Assignee:
Martin Marietta Corporation - Bethesda MD
International Classification:
B05D 100
US Classification:
4273855
Abstract:
A composition and process for improving the curing of concrete, the composition comprising a Singapore dammar resin dissolved in an organic solvent. In a preferred embodiment of this invention, the resin-solvent solution is dispersed in a water-based emulsion by the use of an appropriate emulsifying agent. A preferred organic solvent is mineral spirits, and preferably the organic solvent contains a low enough level of photochemically reactive liquids to meet air pollution requirements such as Los Angeles Rule 66.

Curable Aminoplast Compositions And Catalysts For Curing Same

US Patent:
5025085, Jun 18, 1991
Filed:
Nov 6, 1989
Appl. No.:
7/432233
Inventors:
Carlos A. Piedrahita - Mentor OH
Robert E. Quinn - Cleveland OH
John S. Perz - Mentor OH
Assignee:
The Lubrizol Corporation - Wickliffe OH
International Classification:
C08L 6128
US Classification:
528230
Abstract:
The present invention relates to a curable composition comprising: (A) at least one aminoplast resin; and (B) an amount effective to cure the composition of at least one catalyst which is a sulfo acid, or an anhydride, ester, ammonium salt or metal salt of the acid. The sulfo acid can be exemplified by sulfonic acids, such as 2-acrylamido-2-methylpropane sulfonic acid, or a reaction product of the sulfonic acid and a phosphorus acid or salt, such as a dihydrocarbyl phosphorodithioic acid. The catalyst allows curing of aminoplast resins to be accomplished at low temperatures, while imparting a high degree of water resistance to the cured coating.
