Coating agent, process of forming coating films, primer treatment process, process of repairing concretes, and process of constructing roads

A coating agent is capable of forming a coating film that has enhanced adhesion and adherence to a substrate, and enhanced water resistance as well and composed mainly of an aqueous material. A process of forming a coating agent uses the coating agent, a primer treatment process uses the coating agent, a process of doing repairs to concretes uses the coating agent, and a process of laying down roads uses the coating agent. The coating agent is composed mainly of a polyphenol derivative and containing a polymerizing agent, and has a pH of 9 or less. The polymerizing agent contains a compound having two or more functional groups selected from the group of an amino group and a mercapto group per molecule. In the process of forming a coating film, the coating agent is applied onto a substrate in an alkaline environment having a pH of greater than 9.

THERMALLY CURABLE PIEZOELECTRIC COMPOSITES AND USE THEREOF IN ADDITIVE MANUFACTURING

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. Printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles and a polymer material comprising at least one thermoplastic polymer and at least one thermally curable polymer precursor. At a sufficient temperature, the at least one thermally curable polymer precursor may undergo a reaction, optionally also undergoing a reaction with the piezoelectric particles, and form an at least partially cured printed part. The piezoelectric particles may be mixed with the polymer material and remain substantially non-agglomerated when combined with the polymer material. The compositions may define a form factor such as a composite filament, a composite pellet, or an extrudable composite paste, which may be utilized in forming printed part by extrusion, layer-by-layer deposition, and thermal curing.
