PVA Introduction:

 

       Polyvinyl alcohol (PVA) powder series of products is specializedin construction industry as an additive in all kinds of dry powder putty, dry mortar, tile adhesive, especially used for building putty and Mortar, improving  the flexibility, water retention and increase viscosity of mortar and putty. It’s adhesion very good and used to be widely with paper making, sizing material for textile, adhesive, film, and dry mortar field.

    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 couble be protective colloid as Polymer emulsion

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.
