Presentation title：
Environmental and Health Friendly PU (polyurethane) Adhesive Solutions in Woodworking

Abstract:
The concern of the health risk from volatile organic compouds (VOCs) has been rising in recent years. The organic solvents in conventional adhesives for woodworking and interior decoration are the major source of VOCs, and the solvents can cause irritations and negative health effects on woodworkers and also comsumers.
We have developed a noval solvent-free Liquid Polyurethane Reactive (LPUR) adhesive system suitable for laminating and edge joining applications. It can develop an excellent initial (green) strength whin a very short time, thus overcoming the drawback of weak green strength in the convensional PUR products. The LPUR system also performs low viscosity and good workability at room temperature, therefore it can save lots of energy comsuption and equipment investment when comparing to the hotmelt adhesives.
The environmentally friendly solvent-free moisture-reactive polyurethane adhesive contains highly reactive -NCO and -NHCOO- groups, which readily react with compounds containing active hydrogen and moisture in the air to form urea bond structures.
This study aims to develop liquid polyurethane reactive (LPUR) products that can be operated at room temperature and exhibit high storage stability, by selecting low viscosity polyol-based raw materials and incorporating additives.
