In 1930s, synthetic resin adhesives were used in the woodworking industry. 467,909, filed December 4, 1942. This resin is used to make parts that have a high stiffness, low friction, and amazing dimensional stability. All Purpose Adhesive gel. Used in permanent paper labels and pressure sensitive adhesive. Water-based adhesives come in a variety of chemistries and compositions, and can be categorized as either natural or synthetic polymers. The resin comprises the reaction product of a phenol and/or its homologs with an aldehyde and a modifying material in an alkaline medium, the whole being absorbed by another material, which may be termed an absorbent. Within two years, phenolic resin was applied to plywood as a coating varnish. During the present emergency it is imperative that all so-called "defense" materials be saved or made to serve their maximum purpose. Offers... Polymerized butadiene-styrene multiblock copolymer. Type R (Reaction Resin): Single or multi-component mixture of synthetic resin, mineral fillers and other additives in which the curing occurs by chemical reaction. Cyanoacrylate is the main ingredient of synthetic glue, also known as superglue. This procedure results in a resin that is dry when brought to the completion stage since water of condensation is continuously removed, as it is formed, from the reaction vessel.

The cured adhesive film remains resilient, thus making Rainbow R-104 suitable for most upholstery materials such as … It was discovered by Dr. Harry Coover, in 1942, when he was working for Kodak Research Laboratories towards development of an optically clear plastic for gunsights. Home > Forum > Optimized formulations > Formular of synthetic rubber adhesive. After cooling the resin is ground to pass at least a one hundred-mesh (100) screen. Some are thermosetting plastics in which the term "resin" is loosely applied to the reactant or product, or both. These prior liquid resins, after being made, are hard to transport, have a short life due to the continued condensation, and necessitate the shipping of a large quantity of water at a relatively high cost. © 2004-2020 FreePatentsOnline.com. Proteinous materials, such as: 35 Dried activated sludge Insoluble blood Soluble blood Casein Oleaginous seed meals, as such, heat-treated, or aldehyde-treated; examples of which are: Soya Peanut Cottonseed Flaxseed 3. Actually, Coover first rejected cyanoacrylate … Report provides a comprehensive analysis from industry covering detailed reporting and … When compared to other similar resins, one can see the simple chain structure. The other family of synthetic rubber resins used in PSA formulations are Styrenic Block Copolymers, (SBC).

Both of these t materials are very cheap in comparison to the c expensive resin-forming phenol and aldehyde. Submitting this form implies your acceptance to SpecialChem Terms & Conditions. Starch containing materials, such as: Manioc Wheat flour The above materials may be used singly or in combination as modifying materials or as absorbents. Certain vinyl polymers are elastomers, and these together with the truly synthetic rubbers such as neoprene and nitrile rubber are discussed. & Terms of Use. Used in adhesives and sealants... Emulsion polymerized, styrene-butadiene copolymer. ----------------- 32 purfural ----------------- ------------9 Caustic soda dissolved in --------------- 10 Water --------------------------- 20 The above named materials are put in a reaction cettle fitted with a reflux condenser so that the water formed during the reaction period may be limnated and any of the furfural or cresylic acid that may be carried over through the condenser and formed in a layer below the water to be eliminated, may be returned to the reaction kettle. Provides high cohesive strength, low application viscosity, ease of mixing, low color and heat stability. generation, Resinous molding composition from synthetic aldehyde resins and hydrolyzed ligno-cellulose, Production of phenol-aldehydelignin resins, Corn gluten plastic and method of making same, Plywood board and process of making the same, Adhesive or cement and process for making the same, Furfural resin composition and process of making same. Styrene Butadiene Rubber (SBR) is the most widely used synthetic rubber in adhesives & sealants and is produced from copolymer of styrene and butadiene. This base may be used to form adhesives which in turn are used to glue plywood panels which range in moisture resistance requirements from the highly water resistant exterior type down to the moderately water resistant interior type as determined in tests set forth by the National Bureau of Standards (see above bulletin reference). You would find these materials most commonly used in the automotive and consumer electronic industry. The resin adhesive base described herein can be extended by materials heretofore thought unsuitable for plywood adhesive formulation due to the treatment undergone in their formation. Premium formula, dries clear. performance properties. They have many advantages for use in the woodworking industry. 5 I Neither of these extenders, also referred to herein i as modifying agents and absorbent materials, are t at present regarded as "defense" materials; consequently with a given amount of the "defense" resin-forming materials it is possible by my in-,10 vention to produce a much greater amount of adhesive base, by the addition of said "extenders," e than is achieved with the resin adhesive bases I now used by the plywood industry for a similar purpose. The above named materials are heated to melt the sulfur herein used as the modifying agent, the caustic soda solution is then added and the mixture boiled for twenty-five (25) minutes. 1 except that one hundred (100) parts of activated sludge is used to absorb the resin in place of the insoluble blood. I claim: A process which comprises reacting together cresylic acid, furfural and a modifying agent comprising sulphur at an elevated temperature in the presence of an alkaline catalyst to produce an alkaline dispersible potentially thermosetting resin, adding to the resin an absorbing material comprising insoluble blood, intimately mixing the mass and then cooling, thereby producing a hard, comminutable … Any alkaline catalyst may be used, for example sodium and potassium hydroxide, or any of the so-called alkali metal salts, singly or in combination. The product when cooled is a hard, comminutable substance. This base is now suitable for admixture, In varying proportions dependent upon the quality of adhesive desired, with alkaline-dispersible material to form a new and superior type of plywood adhesive, as set forth in my application Serial No. Resins heretofore used in the manufacture of plywood adhesives have required special equipment or special attention when mixed and applied to the panels. 467,909, filed Dec. 4, 1942, entitled Synthetic resin base adhesive and method of making same, now Patent No. No one single formula adhesive can be used with all stones/tiles and substrates. 16, 1940 2,292,624 Fanthrop --------- Aug. 11, 1942 FOREIGN PATENTS Number Country Date 280,144 Germany ---------.

Crystal-clear synthetic resin adhesive for a universal application. By "modifying agents" as used in the present description and claim, I refer to materials from the above list which, when added to the reacting ingredients before or during the reaction, serve to modify or change the characteristics of the initial resin. & Terms of Use.
