What is PVA Glue?

PVA glue, also called Polyvinyl Acetate glue or White glue, is a type of glue that is widely used for various bonding applications. It is a synthetic polymer emulsion that belongs to the polyvinyl acetate family. PVA glue is known for its versatility, ease of use, and wide range of applications.

What is PVA Glue's features?

1. Water-based

PVA glue is water-based, meaning it contains water as a solvent. This makes is easy to clean up with water and less toxic compared to some solvent-based adhesives.

2. Versatility

PVA glue is versatile and can be used for bonding a variety of materials, including paper, cardboard, wood, fabric and porous surfaces.

3. Drying Time

It has a relatively short drying time, and it dries to a clear or translucent finish. The drying time can vary depending on factors such as humidity and the thickness of the glue layer.

4. Non-toxic

PVA glue is generally considered non-toxic, making it suitable for use in various crafting projects, schools and household applications.

5. Flexibility

It remains somewhat flexible after drying, which can be advantageous in applications where some degree of flexibility is needed.

6. Solubility

PVA glue is soluble in water when wet, which allows for easy cleanup and adjustment of glued pieces before the glue sets.

7. Adhesion Strength

While PVA glue provides good adhesion for many applications, it may not be suitable for load-bearing or structural applications. Its strength is typically suitable for bonding materials with moderate stress.
