Title: Innovations of Jinping Wu in Pressure Sensitive Adhesives
Introduction
Jinping Wu is an accomplished inventor based in Exton, PA (US). He has made significant contributions to the field of pressure sensitive adhesives, holding 2 patents that showcase his innovative approach to adhesive technology.
Latest Patents
His latest patents include advancements in 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 and an OH number between 0.01 mg KOH/g to 100 mg KOH/g. Additionally, they incorporate at least one mono (meth)acrylate functional monomer and at least one 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 application of heat, resulting in films with excellent peel strength, tack, and shear resistance. Notably, these systems contain less than 1 wt % of solvent and less than 1 wt % of water or are entirely free of both.
Another patent focuses on removable coating systems and methods. These coating compositions also include at least one urethane (meth)acrylate oligomer and at least one cycloaliphatic (meth)acrylate. They may optionally contain a photo-initiator, adhesion promoter, pigment, dye, and/or plasticizer. The compositions can be hardened 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.
