PVA-BASED GLUES

27.03.2018

PVA-based glues are often used in manufacturing, repair work and at home. PVA Glue is one of the most common adhesives and is used various applications. It is non-toxic, safe for human health and easy to use.

Many wholesale companies and stores offer diverse brands of adhesives in a wide price range. Selecting a brand of PVA glue is based on the substrates to be bonded, such as paper, wood, fabric or other surfaces. The material to be bonded determines the selection process. PVA glues differ in color from snow-white to yellow and have different properties.

PVA Glue for the printing industry and packing

To accomplish tasks such as binding, producing boxes, paper bags, we use polyvinyl acetate dispersion or PVA glue. Polyvinyl acetate is a vinyl acetate polymer used in adhesives and paints. It is economical to use, has a light color and dries relatively quickly. The glue looks silky and smooth when applied to a surface with tools or special equipment. Special properties of PVA allow long-term storage of printed products bonded together with this glue. Adhesive seams remain flexible, not brittle, and do not turn yellow during long term storage in a dry environment.

Waterproof PVA glue for woodworking and furniture production

Mold and moisture resistance are two main advantages of using waterproof PVA glues, although not all of them are watertight. Note that waterproofness refers to counteracting the effects of water or moisture ingress. Water tightness is counteracting the effects of water or moisture ingress, as well as immersion in water. According to the DIN norms, waterproof PVA glues are of four types and are marked from D1 to D4. The higher the number, the better resistance to water. To choose a type of glue for wood and furniture properly, we recommend that you read the label carefully or ask for assistance from the manager who works with your company.

PVA Glue for repair and construction

In repair work, PVA-based glue can be used for gluing all types of carpets, linoleum, various types of wallpaper, facing tiles and synthetic decorative paper-based coats. When mixing PVA glue and water in equal parts, you get a very good sealant for plastering or priming wall surfaces before painting or wallpapering.

In the construction trade, PVA glue is used for the installation of fiberboard, chipboard, OSB, MDF and plywood, as well as beams and rails. PVA dispersion is added to putty, concrete and plaster solutions to increase the strength and water tightness characteristics.

Tips for using PVA glue

  • When using PVA glue, at least one of the surfaces to be glued must be porous so that moisture can be absorbed. For example: glass with wood, but not glass with glass.
  • Remains of PVA glue can be cleaned with warm soapy water.
  • PVA glue dries faster in a well-ventilated room or an air-conditioned room.
  • PVA works best if the parts to be glued are clamped under pressure (clamp, machine, etc.).
  • Waterproof PVA adhesives are not watertight.
  • If a PVA glue is suitable for gluing wood, it is also suitable for gluing paper or cardboard.
  • PVA Glue cannot be frozen. If it freezes the adhesive structure breaks down and the glue loses its adhesive properties.
  • It takes 24 hours to reach full adhesive joint strength.
