PVA Powder is the selection of high quality of PVA, and environment-friendly water soluble polymer. It takes liquid nitrogen as a medium, Crushing

 processing in low temperature environments, have a good at film forming property,

 emulsibility, cohesive property .the film it product has great force , solvent resistance,

abrasion resistance,tensile strength and oxygen denial property.Due to PVA have

 hydrophilic group and hydrophobic group,so PVA could be protective colloid as

 Polymer emulsion.

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, 

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 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 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: 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 should use clear conveyance and

 avoid moisture,rain,sun and carry gently to prevent smash package.
