CAS:52591-27-2，2-(Perfluorobutyl)Ethyl Acrylate

The invention discloses an anti-fouling resin and a preparation method thereof. The anti-fouling resin comprises grafted resin and an acrylic monomer, and the acrylic monomer comprises a fluorinated acrylic monomer; the grafted resin is prepared from a first solvent, a first catalyst, polyol resin and carboxylic acid derivatives. According to the anti-fouling resin provided by the invention, after the base resin is doped and added, excellent anti-fouling performance is provided, and meanwhile, the anti-fouling durability of the anti-fouling resin can be kept. According to the present invention, the acrylic acid monomer with the fluorine-containing benzene ring is introduced into the anti-fouling resin system, and the good hydrophobic and oleophobic performance of the aromatic group is utilized to form the anti-fouling effect similar to the anti-fouling effect of the fluoroalkyl chain;

The present invention is directed to a curable and debondable two-part (2K) adhesive composition comprising: i) a first part comprising: (meth)acrylate monomer; co-polymerizable acid; and, an electrolyte; and, ii) a second part comprising: a first curing agent for the monomers of said first part; a second curing agent for the monomers of said first part; and, a solubilizer.

A composite particle is provided that comprises a base particle comprising at least a pigment or dye and cross-linked polyurea, a plurality of hydrophilic oligomeric groups, and a plurality of amine groups on the exterior portion of the base particle, and a steric stabilization polymer which is chemically bonded or physi-sorbed on the surface of the base particle. The cross-linked polyurea may form a network throughout the base particle. A method of making the composite particle includes providing either a solution containing a dye or a dispersion containing a pigment in a water-dispersible polyfunctional isocyanate dissolved in a water-miscible solvent, forming an emulsion of the solution/dispersion in water, agitating the emulsion while the polyfunctional isocyanate is converted into a cross-linked polyurea, and separating the composite particle containing the cross-linked polyurea and the dye/pigment from the emulsion.
