Polyvinl Alcohol - PVA Powder Applications
WOTAIchem PVOH powder is an excellent additive for building materials like concrete and cement mortar. It has impressive features in your construction projects.
PVA powder can effortlessly dissolves in cold water at room temperature. Eliminating the need for heating.
Ideal for producing cold water adhesives, putties, tile adhesives, dry mix mortars, and suitable for wallpaper and polypropylene fabric applications.
Polyvinyl alcohol powder will soften when heated. There is no obvious change below 40℃ or above 160℃. Long-time heating will gradually put on color.
The decomposition generates water, acetic acid, acetaldehyde, and butenal heating up to 220 ℃ or above.
Powdered PVA is particularly well suited for applications where chemical resistance is important.
It is virtually unaffected by weak acids, alkalis, or organic solvents and has high oil resistance. It’s great for applications where it will be exposed to chemicals.

FAQs
Have any questions? We are always here to help you.
The duration of dissolution doesn’t significantly affect the structure of PVA powder. However, the PVA viscosity may slightly decrease.
Inspecting the PVA solution for signs of mold or black spots is essential, especially if no preservatives were added. It can generally be used if the solution appears free of mold or discoloration. The risk lies in potential impurities causing mold growth.
Preparing and using the PVA solution as needed is recommended to ensure optimal performance.
PVA is generally stable in cement. Yet, various factors contribute to mortar consistency. Ensuring proper mixing procedures is essential to enhance stability. Then, consider the mortar formulation for an optimal balance.
> WOTAIchem recommendation: Add PVA-ADH or BGH models for your mortar formula.
Polyvinyl alcohol powder is heated and intensively stirred in water at temperatures ranging from 90 °C to 100 °C to create PVA solutions. This process requires two hours of stirring at a high speed, and the final result will be a clear and transparent solution that meets customer requirements.
Polyvinyl alcohol is produced through the polymerization of vinyl acetate and subsequent partial hydrolysis – resulting in vinyl acetate monomer as the primary raw material. This method yields a substance with various industrial applications.
The results of our studies show that PVA solution added to fresh cement paste reduces stiffness as well as compressive strength.
