pva for construction
PVA fine powder PVA HWP-05S,HWP-20S and HWP-24S are specially designed for cement additives and building
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 quali-
ty.(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.

b.construction :upholstery industry 107 glue, it's used as an additive of cement and mortar, inner and outer wall paints, and moulding board binder.

c.chemical industry: it's used as a polymer emulsifying agent, dispersing agent and used to produce PVOH formal, PVOH acetal and PVOH butyral.

d.paper industry:It's used as an adhesive in lumbering and paper-making industries.


The advantages of PVA as a mold release agent are listed as following.

●Good film forming property, without cracking

●Anti-adhesive release effect, even when thinly applied

●Impermeability of PVA film to the organic material used, e.g. styrene

●The PVA film which adhesives to the cast article can be peeled off by hand
