  • Patent number: 9873761
    Abstract: A thermosetting resin composition has particular applications in three dimensional (3-D) printing. The thermosetting resin composition exhibits high performance and is characterized by a high temperature two stage cure resin composition. The thermosetting resin composition comprises cyanate esters and other high temperature resins, photo curable monomers, photo initiator, metal catalyst or ionic liquid catalyst. The thermosetting resin composition cures at room temperature to form 3-D objects and upon further post cure these objects exhibit high temperature properties enabling use at temperatures exceeding 150 C.

  • Patent number: 9596753
    Abstract: An ultra low loss dielectric thermosetting resin composition has at least one cyanate ester component (A) and at least one reactive intermediate component (B) that is capable of copolymerization with said component (A). The invention is a cyanate ester resin of the form: Tn-[W-(Z)f/(H)1?f-W]n?1-[W-(Z)f/(H)1?f-(OCN)f/(R)1?f]n+2, wherein T is a 1,3,5-substituted-triazine moiety (C3N3); W is a linking atom between triazine and either component A or component B; Z is component (A); H is component (B); OCN is a cyanate ester end group; R is a reactive end group of component B; n is an integer greater than or equal to 1; and f is a weight or mole fraction of component A. The composition exhibits excellent dielectric properties and yields a high performance laminate for use in high layer count, multilayer printed circuit board (PCB), prepregs, resin coated copper (RCC), film adhesives, high frequency radomes, radio frequency (RF) laminates and various composites.
