Click for automatic bibliography While Applicants' invention works well at room temperature, more rapid dissolution may be obtained by heating the 1,2-dialkyl imidazole-containing formulation to a temperature of about 50 to about 100° C. The 1,2-dialkyl imidazole-containing formulation may be applied to the polyurethane foam in any conventional manner. After said period of time, agitation of the surfaces to be cleaned of the foam via wiping, brushing or scraping is preferred. Rods that had been coated with cured fiberglass were treated with acetone to remove any fiberglass residue; those that had been coated with cured flexible or rigid polyurethane foam were treated with methylene chloride. Polyurethane polymers are traditionally and most commonly formed by reacting a di- or triisocyanate with a polyol.Since polyurethanes contain two types of monomers, which polymerise one after the other, they are classed as alternating copolymers.Both the isocyanates and polyols used to make polyurethanes contain, on average, two or more functional groups per molecule.. Polyurethanes are used in the … The other solvents are either toxic, suspected carcinogens, or very volatile, and thus present health and safety problems. Once it cures, you'll have to scrape or sand off unwanted foam. In the examples recorded in the table below, the following procedure was used. Copyright 2020 FindAnyAnswer All rights reserved.

Optionally, other additives may be employed in the formulations of the present invention. A high water saturation of the polyurethane foam would help to a reduce the extent of the chemical clogging of the geotextile. Those skilled in the art will appreciate that the portion of conventional solvent(s) in a formulation which should be replaced with 1,2-dialkyl imidazole for a given polyurethane foam involves a balance of possible reduction in dissolution power versus the reduction or avoidance of additional expense and/or environmental, health and safety risks associated with the conventional solvents. filed Dec. 13, 1990. It can also dissolve acrylic solvents, partially cured polysulphide sealants and de-bond hot metal butyl. Flexible polyurethane foam helps in providing comfort to everyone, every day. What is the meaning of dissolve for kids? The foams were then allowed to cure for two days or more before dissolution studies were begun. The polyurethane foam under the geotextile reduced the contact between the geotextile and air. Suitable surfactants include potassium oleate, the dioctyl ester of sodium sulfosuccinic acid, sodium alkylnaphthalene sulfonate, sodium alkylbenzene sulfonate, and the like. Preferably, the portion of conventional solvent replaced with 1,2-dialkyl imidazole in a formulation containing one or more conventional (non-1,2-dialkyl imidazole) solvents will be such that the 1,2-dialkyl imidazole and the conventional solvents in the formulation are present in a weight ratio of 1,2-dialkyl imidazole to total conventional solvent of about 4:1 to about 1:4. The rods were then coated with a rigid or flexible polyether-based foam formulation having the following components: Rigid Foam Thanol ® R-350-X 36.9 DC-1931 (silicon surfactant) 0.5 R11 (trichlorofluoromethane) 15.0 TEXACAT ® TD-33 0.3 Rubinate M2 (polymeric isocyanate) 49.6 1 Dow Corning; 2 ICI. The present inventive process, by substituting in whole or in part 1,2-dialkyl imidazole for the more hazardous prior art solvents, reduces many of the health, safety and environmental hazards associated with the prior art solvents. Since polyurethane is a chemical, we need to use a solvent to dissolve it. If polyurethane foam dries on your skin, rub off as much as you can with a pumice stone. How long does it take for dissolvable stitches to dissolve after septoplasty? Generally, rigid polyurethane foams are based on polyols having a molecular weight less than 1000, and more often from about 400 to about 800.
