WEFV is committed to the research of home decoration environmental protection materials, focusing on new home decoration seams, ceramic tile back adhesive, waterproofing, binders and other products. Formerly known as WEFV Research Institute in Florida, USA, it was founded in 1988 by Wefv Davis, a famous professor of new polymer material science at Florida State University, and 15 assistants, aiming to study new home decoration materials, and then a number of patented technologies were obtained. In the 1990s, Professor WEFV noticed that problems such as bacteria mildew and blackening caused by the use of traditional white cement to fill gaps in ceramic tiles affected home safety, and set up a project within the Institute to develop a new material to solve the gap filling of ceramic tiles.
