PVA Polyvinyl Alcohol pva 0399
0399 Polyvinyl Alcohol is a few kind of synthetic with water souble high-
molecular polymer.The main specification includes degree of polymerization & alcoholysis degree
with other specical performance. Polyvinyl Alcohol is manufactured by polymerization of vinyl
acetate in methanol solvent, then undergoing alcoholysis via advanced belt-process of low- alkali. After grinding, drying and packing, the end PVA products are achieved.

physical and chemical properties
aqueous solution, non toxic and harmless, security and environmental.
Chemical resistance: At normal temperature, its PH value is about 5-7, viscosity is steady,
hardly be impacted by weak acid, weak base and organic solvent(ester, ketone, higher alcohols,
hydrocarbon), has high oil resistance.
Compatibility: it can be miscible with starch, synthetic resin, cellulose
Main Applications:
PVA0399 main used in the field of paper manking,especially used as pigment
adhesive.With good adhesion,good filming and strengthing to paper, PVA water
solution can be used as pigment adhesives to substitute casein and starch
which is more expensive and easy to be corrosible.The whiteness and gloss
of the wove paper coated with PVA solution will be perfect,not easy to be
crimped and with lower cost.Therefore,it is widely used in art paper ,
craft paper,clothing paper and other high-grade paper.
Usage method
KP series can be used in powder building materials , after stirring and mixing evenly,
it could be use. Addition of advice: 0.3-3%of the totle putty powder.
KP series use 100-120mesh when product dry glue powder, below 100 mesh it dissolves slow,
difficult completely dissolve, when over 120 mewsh, it is easy to agglomerate.
Dry-mixed mortar use 80-120mesh. Powder putty use above 120 mesh, because
below 120 mesh it is difficult to dissolve and make the surface unsmooth.
Package&storage transportation
Packing: Paper-plastic package with plastic film, 20kg&25kg per bag.there are COA
in every product,and clear&firm mark in every bag.including trademark,name,model, lot number,
net weight,manufacturer ect...
Store: KP line products should be stock indoor where is dry& well-ventilated,
room temperature is 5-30℃, Stored in batches. do not near the power, prevent humid,
avoid sun exposure. strictly prohibit storage with volatile chemicals to prevent adsorption modification.
Transportation: when transport KP line products shuld use clear conveyance and
avoid moisture,rain,sun and carry gentlyto prevent smash package.
