PVA used for platen adhesive
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 .

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,
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.
pachage&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.
