摘要： Disclosed herein are an aqueous dispersion including cationic polyvinyl alcohol modified polymer particles, an aqueous electrocoating material containing the dispersion and a process to produce an at least partially coated substrate using the aqueous electrocoating material. The aqueous dispersion can be prepared by reacting an intermediate including at least one polyvinyl alcohol polymer chain with a compound including at least one epoxide group and a least two blocked primary amino groups. Aqueous coating compositions including the aqueous dispersion result in improved leveling properties during film formation as well as an improved edge protection of the substrate without negatively influencing the surface roughness and adhesion as well as the deposition properties.

摘要： The invention relates to a method of sealing, coating or/and aerodynamic smoothing of at least one connecting element that protrudes from a surface or/and for sealing, coating or/and aerodynamic smoothing of a surface at a gap or at an uneven connection site with a sulfur-containing SCOD sealing compound at at least one application site, especially on an aerospace component, with at least one nozzle element and with at least one irradiation unit, which is characterized in that i) a nozzle element contains a mixed sealing compound and is guided or/and mounted over the connecting element protruding from a surface, over the gap or/and over the uneven connection site, ii) the connecting element protruding from the surface, the gap or the uneven connection site is covered fully with sealing compound, the sealing compound forming a sealing compound cover essentially in the form of a sealing compound cap, a coating or/and a mound-shaped or bead-shaped elevation, iii) the nozzle element or at least a portion is raised if required from the surface having the sealing compound cover, and iv) the curing of the sealing compound is initiated with the aid of at least one irradiation unit by energy input and by release of a latent catalyst or is brought about by direct activation of at least one reaction component, such that the mixed sealing compound subsequently cures or/and cures further. The invention also relates to a corresponding apparatus, to the aerospace vehicle treated in this way and to the use of the method and the apparatus.

摘要： Some variations provide a thermoformable and thermosettable bismaleimide-thiol-epoxy resin composition comprising: a thiol-endcapped bismaleimide monomer or oligomer; a thiol-containing species; an epoxy species; a curing catalyst; and optional additives. Other variations provide a method of making a bismaleimide-thiol-epoxy resin composition, comprising: providing a starting bismaleimide, a starting multifunctional amine, a starting multifunctional thiol, an acid catalyst, and a solvent to form a starting reaction mixture; reacting the bismaleimide, the multifunctional amine, and the multifunctional thiol to form a thiol-endcapped bismaleimide monomer or oligomer; providing a thiol-containing species; providing at least one epoxy species; providing a curing catalyst; and combining the thiol-endcapped bismaleimide monomer or oligomer, the thiol-containing species, the epoxy species, and the curing catalyst, to form a bismaleimide-thiol-epoxy resin composition. Other variations provide a method of thermoprocessing comprising: thermoforming, but not completely curing, a bismaleimide-thiol-epoxy resin composition; and, at a later time, completely curing the thermoformed bismaleimide-thiol-epoxy resin.

摘要： This invention relates to fusion bonded epoxy rebar powder coating compositions of enough latency overtime, which cure in seconds upon residual heat up to 239.0° C., exhibiting low temperature flexibility to achieve crack-free rebar bending at −45° C. and a glossy finish without yellowing or discoloration. This invention further relates to rebar powder coatings compounded using suitable dihydrazide amines as the curing agent, in combination with an executive resin blend including a compatible toughening epoxy, and a synergic catalyst package to meet the intended application challenges.
