Beschreibung
Zusammenfassung:	Curable compositions include: a) at least one (meth)acrylate monomer or oligomer and b) at least one mono-functional (meth)acrylate monomer comprising a polycyclic moiety having at least three rings that are fused or condensed. The compositions may comprise an initiator system to render the compositions as curable. The compositions may comprise both the a) and b) components in an amount from about 30% to about 70% by weight. The compositions described herein are advantageous with respect to properties such as viscosity, toughness, tensile strength and tensile elongation. Due to their advantageous properties, the compositions are viable for a wide range of applications including coatings, adhesives, sealants, inks and stereolithography. The compositions are liquid at ambient temperature and impart a high glass transition temperature, Tg, without sacrificing other properties, such as elongation. The compositions are useful in 3D printing.
