With a total of 2 patents, Lau's work has the potential to enhance the efficiency and sustainability of paper products.

Latest Patents

One of Lau's latest patents is for an epoxidized polyalkyleneamine-amide wet strength resin. This invention describes an improved cationic wet strength resin prepared from an epichlorohydrin-ammonia intermediate reaction product, polyalkyleneamine-amide, and epichlorohydrin. This resin not only efficiently imparts wet strength to paper but also ensures that the treated paper is easier to repulp than paper treated with conventional epoxidized polyalkyleneamine-amide.

Another notable patent is for a binder for pre-moistened paper products. This invention involves a premoistened towelette or wiper type paper product that maintains high wet strength when stored in an acidic pH medium and during usage. It also exhibits lower wet strength when immersed in a neutral or alkaline pH medium for disposal in conventional sewage systems. The product comprises a non-woven fibrous web treated with an improved polymeric binder made from a copolymer of glyoxal and polyvinyl alcohol. This binder maintains high wet strength during usage and readily breaks up during flushing, making it suitable for external cleansing of the human body.
