0588   

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

   Water-solubility: it dissolves quickly in room temperature water, its transparent is

 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 derivatives & surface active agent and has better stability

Main Application:

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, 

improveing 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 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 

avoidmoisture,rain,sun and carry gentlyto prevent smash package.
