|Acetoacetate functional latex emulsions cured with phenolic resins and coating compositions formed therefrom|
The present invention includes coating compositions and methods for coating substrates using the coating compostions. In some embodiments of the invention, a coating composition is prepared by a method including the steps of: a) preparing a latex emulsion by a method including mixing an ethylenically unsaturated monomer component in a carrier to form a monomer emulsion, and reacting the monomer emulsion with an initiator to form the latex emulsion, wherein the latex emulsion is prepared using an acetoacetate compound, b) preparing a hydroxyl functional oil graft copolymer by a method including reacting an epoxidized vegetable oil with a hydroxyl functional material in the presence of an acid catalyst to form a hydroxyl functional oil polyol, and reacting the hydroxyl functional oil polyol with an ethylenically unsaturated monomer component in the presence of an initiator to form the hydroxyl functional oil polyol graft copolymer, and c) blending the latex emulsion and a crosslinker then adding the hydroxyl functional oil graft copolymer to form the coating composition.
|Methods for reducing the solubility of phenolic resins using latent acids|
Resin compositions having a reduced solubility and methods for making and using same are provided. In at least one specific embodiment, the resin composition can include a phenolic resin, a latent acid, a catalyst, and a liquid medium.
|Resin system for composite downhole frac plug and bridge plug tools and related methods|
A new resin blend is disclosed, which may be referred to as a hybrid resin. The resin blend includes an effective amount of benzoxazine resin or benzoxazine derivative mixed with at least one of epoxy resin, phenolic resins and other thermosetting polymers at varying ratios.
|Oil and gas well proppants of silicone-resin-modified phenolic resins|
Proppant particles coated with an arylolic resin/silicone resin copolymer, wherein the silicon resin contains d units and t units, are suitable for fracturing operations in geological formations and retain their deformability over time without becoming excessively brittle.. .
|Methods for surface coating of cathode material lini0.5-xmn1.5mxo4 for lithium-ion batteries|
A high-voltage lithium-ion battery cathode material includes lini0.5-xmn1.5mxo4 (0≦x≦0.2, m═mg, zn, co. Cu, fe, ti, zr, ru, and cr), which is coated with a coating material, which may be a carbon coating material, a metal phosphate coating material, or a combination thereof.
|Alkyl phenolic resin and method of preparation thereof|
Described herein are alkyl phenolic resins and methods of producing them. The content of residual phenol in the alkyl phenolic resin may be less than about 2% w/w, the softening point of the alkyl phenolic resin may be about 85° c.
|Carbon-ceramic brake disk and method for manufacturing same|
A method of manufacturing a carbon-ceramic brake disc of the present invention includes a first step of mixing carbon fibers with phenolic resins to produce a mixture; a second step of putting the mixture into a mold pressing the mixture by a press to produce a molded body; a third step of carbonizing the molded body; a fourth step of machining the carbonized molded body; a fifth step of coating the machined molded body with liquid-phase phenol to be cured; a sixth step of melting silicon to be infiltrated into the cured molded body that has been coated with the liquid-phase phenol; and a seventh step of grinding the molded body that has been infiltrated by the silicon. According to present invention, the cracks do not occur in the anti-oxidation coating layer..
|Low free formaldehyde phenolic resins for abrasive products|
The present invention provides process for the manufacture of an aqueous resin composition comprising a phenolic formaldehyde (pf) resin, which process comprises the steps of: providing a formaldehyde and phenolic compound, reacting said compounds in a condensation reaction in the presence of a catalyst, after completion of the condensation reaction to react with free formaldehyde, determining the free formaldehyde content of the resin composition, adding a pre-calculated substantially stoichiometric amount of modifying compound containing a primary amine group to reduce the amount of free formaldehyde in the resin composition to less than 0.1 wt % (relative to the total weight of the aqueous resin composition), and optionally distillation of the reaction product.. .
|Powder coatings compositions|
A solid epoxy resin powder coating composition which includes a divinylarene dioxide resin as one component; and wherein the solid epoxy resin powder coating composition can be formed by blending or reacting various other components with the divinylarene dioxide resin. For example, other components can include other epoxy resins; phenolic resins; or monomeric and/or polymeric isocyanates.
