Polyvinyl Alcohol 088-20(1788)
Polyvinyl Alcohol is a few kind of synthetic with water soluble high-molecular polymer. The main specification includes degree of polymerization & alcoholysis degree with other special 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.

Main Applications:
KP series can be widely used dry powder, powder putty, dry-mixed mortar, oilfield auxiliary chemical, in powder building materials, caking agent&bond of plastering anhydrite. Especially suitable to be used as interior & exterior wall putty and construction mortar, the main function is bonding, improving the flexility, water-retaining property, reducing friction, enhancing the work efficiency and quality(to prevent the crack &fall off from the floated coat, add adhesive strength and smooth texture).
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 total putty powder.
KP series use 100-120mesh when product dry glue powder, below 100 mesh it dissolves slow, difficult completely dissolve, when over 120 mesh, 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: kraft paper package with plastic film inside, 20kg&25kg per bag.
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 should use clean vehicles and avoid moisture, rain, sun and carry gently to prevent damage.
