My invention, on the other hand, relates to the formation of a so-called "dry" resin, which does not have to undergo any drying process in its manufacture, and which may be readily ground to a fine powder at room temperatures, and has much broader limits on its life because it is in a dry form and may be stored for an indefinite length of time. However, I prefer to use sodium hydroxide. Synthetic resins are of several classes. 2,430,736. All Purpose Adhesive gel. Sulfur 2.

It is exceptional in adhesion and increases the adhesive power of glues. The modifying materials and absorbing materials which have been found suitable for my process are the following: 1. ----------------- 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. These materials are refluxed in order to form a resin which, before or after the addition of the "absorbent" material, will form a product which hardens at about 20° C. in the presence of an alkaline catalyst such as caustic soda in the amount of about ten per cent (10%) figured on the basis of the furfural added. Accelerator (also see catalyst): Usually part B of an adhesive formula, it causes and/or speeds the resin’s curing process. Both of these t materials are very cheap in comparison to the c expensive resin-forming phenol and aldehyde. Aside from the matter of "defense" there is here a pronounced economic saving in that a relatively small amount of the more expensive phenol and aldehyde is made to do the work of a relatively large amount of said materials which are being used at the present time. 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 substance suitable for use as an adhesive. Used in a wide range of adhesives.

R 104 is a spray grade, non flammable upholstery adhesive based on a special synthetic resin rubber combination that displays good aging properties. Being non-toxic and having no odour, polyvinyl alcohol is another polymer that is specially useful as an adhesive in contact with food. I Parts by weight Cresylic acid ------------------------ 216 lulfur --------------. The phenols and aldehydes selected are of such a nature as to form a resin in the absence of water, except for the limited quantity of water which serves as the solvent for the catalyst, and the water of condensation formed in the reaction. 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. Styrene butadiene rubber. 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. This resin is added to paints for increasing their finish and durability. & Terms of Use.

This resin is made in a kettle with a reflux condenser so arranged that the water dispelled can be run off, whereas any of the cresylic acid or furfural that comes off can be returned to the reaction chamber. These resins have styrenic endblocks with mid blocks of either polyisoprene, (SIS) or polybutadiene, (SBS). Used as a base polymer for hot melt and solvent-based adhesives. Used in a wide range of adhesives. From the mixer in which the absorbent material is added the resin is allowed to flow into pans or some other similar receptacle to cool, or it may be cooled in any other suitable manner. One hundred (100) parts of insoluble blood (absorbing material) are then added and mixed in thoroughly and the resultant resin is poured on to trays to cool. 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.
