Latest Patents

Dong's latest patents include innovative pressure-sensitive adhesive (PSA) compositions. These compositions feature at least one urethane (meth)acrylate oligomer with a molecular weight ranging from about 2,000 g/mol to about 50,000 g/mol, along with a mono (meth)acrylate functional monomer and a tackifying resin. The PSA systems are designed to be liquid at a temperature of 25°C ± 2°C, with a viscosity of 15,000 cPs or less. They are capable of forming smooth, uniform coatings or films upon curing without the need for heat, resulting in films with excellent peel strength, tack, and shear resistance. Additionally, these systems contain less than 1 wt % of solvent and water or are completely free of both.

Another significant patent involves removable coating systems and methods. These coating compositions also include a urethane (meth)acrylate oligomer and at least one cycloaliphatic (meth)acrylate. They can be cured through various methods, including exposure to radiant energy, electron beam radiation, heat, or chemicals. Upon hardening, the coating typically exhibits two phases: a soft phase with a Tg between -50°C and 0°C, and a hard phase with a Tg between 60°C and 120°C.
