PVA 0588 Powder 20mesh
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
Polymer emulsion.

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 Application:
KP series can be widely used dry powder, powder putty, dry-mixed mortar, oilfield auxiliary chemical, in powder building materials, caking
& 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.
