PVA fine powder are specially designed for cement additives and contruction industry. They improve plaster properties such as flexibility, water retention, and increase plaster viscosity as well. In addition, they do not only reduce the friction of plaster but also enhance its working capacity and quality (Prevent cracking and shedding of plaster, increase adhesion and smoothness of cement.) To mix desired amount of PVA with cement well before water is added prevents the lumping of PVA.
