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.

Have any questions? We are always here to help you.

Can PVA powder be used after dissolving for over a month? Will it affect performance?

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.

What is the role and mechanism of Polyvinyl Alcohol Powder (PVA Powder) in putty?
PVA Powder enhances putty by forming a strong framework structure as it dries. This structure combines a rigid skeleton from inorganic materials with a flexible film created by PVA, similar to small springs on a frame.
Adding PVA to mortar can boosts putty’s cohesion and resistance to cracking. It slightly reduces water resistance but doesn’t affect overall waterproofing in cement-based putty.
Is PVA powder stable in cement?

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.

How do you mix PVA powder?

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.

What is PVA powder made of?

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.

Does PVA fully dissolve in water?
Yes! PVA fully dissolves in water when you follow the instructions. It depends on factors like the type of PVA and water temperature. Stir it well for complete dissolution. Note that additives or high temperatures can affect it, so follow WOTAIchem guidelines for best results.
Can Polyvinyl Alcohol Powder (PVA Powder) replace VAE RDP powder?
No, PVA Powder can’t fully replace RDP powder. They serve different purposes. VAE RDP improves adhesion and viscosity during construction, but PVA Powder lacks durability and weather resistance, making it unsuitable for complete substitution.
Does PVA make concrete stronger?

The results of our studies show that PVA solution added to fresh cement paste reduces stiffness as well as compressive strength.
