    Abstract: A method of preparing a thermoplastic, water-soluble, phenolic aldehyde resin and the composition are provided to enhance the flexibility and resistance to compression fatigue breakage of glass fibers to which the resin has been applied. The method involves two steps. In the first step, the phenolic compound and the aldehyde are reacted to less than 100 percent completion in an amount so that the aldehyde to phenolic compound ratio is in the range of about 0.6 to about 1.5 and at an acidic pH and for a period of time equivalent to about 3 hours to about 10 hours when the temperature is in the range of about 55.degree. F. (13.degree. C.) to about 90.degree. F. (32.degree. C.) to produce a resinous mixture. In the second stage the pH of the reaction is adjusted within the range above about 7.0 to about 7.

  • Patent number: 4443569
    Abstract: The invention relates to thermosetting, cathodically depositable, aqueous electrocoating compositions which are produced by reacting a nitrogen base-containing binder, which contains tertiary amino groups and primary and/or secondary OH groups, with metal compounds, which are sparingly soluble or insoluble in water, of cobalt, copper, lead, nickel and/or manganese at temperatures between 100.degree. C. and 150.degree. C. under an inert gas. The resultant products are subsequently protonated with an acid and diluted with water in a manner known per se to yield electrocoating paints having a solids content of from 5 to 25% and pH values of 5 to 8. Octoates, naphthenates, borates, and also acetyl acetonates are preferred to be used as the metal compounds which are sparingly soluble or insoluble in water.

  • Patent number: 4405744
    Abstract: A filler for paper, card or board which has a good retention and consists of an inert core material and a hydrophilic coating, which consists of polyacrylamide having a molecular weight of 10.sup.5 to 10.sup.7 or of a mixture of this polyacrylamide with a urea-formaldehyde condensation resin. The filler is prepared by suspending the inert core material in an aqueous solution of a polyacrylamide having a molecular weight of 10.sup.5 to 10.sup.7 or in an aqueous solution of such a polyacrylamide and a urea-formaldehyde condensation resin, and drying this suspension by spray drying or in a stream of hot air. This crosslinks the initially water-soluble polymer and forms a coating, adhering to the core, which is insoluble in water but is hydrophilic and swells, and becomes tacky, in the presence of water.

  • Patent number: 4355131
    Abstract: An aqueous alkaline dispersion of a rubbery graft or over polymerized copolymer of a diene and a vinyl pyridine on a polyacrylate seed (core or substrate), said acrylate polymer having a Tg of not above about -20.degree. C., desirably also containing a polybutadiene, and a water soluble, heat reactable phenolic resin, in certain amounts is useful in forming an adhesive for bonding glass fiber reinforcing elements or cords to rubber compounds or stocks. After dipping the glass fiber cord in the one-step adhesive dip, the coated cord is heated to dry it and heat cure or heat set the adhesive on the cord. Thereafter, the adhesive containing glass fiber cord is combined or laminated (calendered) with a curable rubber compound and the resulting assembly is cured to form a composite in which the glass fiber cord is bonded to the rubber by means of said adhesive.
