PVA-based glues are often used during manufacturing, repair work or at home. PVA Glue is one of the most common adhesives for 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 bracket. The necessary brand of PVA glue is selected based on substrates to be bonded, for example: paper, wood, fabric or other surfaces. This narrows the selection process. PVA glues differ in color: from snow-white to yellow and have different properties.
PVA Glue for printing industry and packing
To fulfill such kinds of works 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 also economical in use, has a light color and dries quickly enough. The glue looks silky and smooth when applied to the 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 constant dry storage.
Waterproof PVA glue for woodworking and furniture production
Resistance to mold and moisture resistance are two main advantages when using waterproof PVA glues, although not all of them are watertight. Note that waterproofness refers to counteracting the effects of water or moisture ingress. Watertightness 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 glue has 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 help the manager who works with your company
PVA Glue for repair and construction works
During repair work, PVA-based glue can be used for gluing all types of carpets, linoleum, various types of wallpaper, facing tiles, synthetic decorative paper-based coats. When mixing 50/50 PVA glue and water, you get a very good sealant for plastering or priming wall surfaces before painting or wallpapering.
During construction works, PVA glue is used for installation of fiberboard, chipboard, OSB, MDF, plywood, as well as beams and rails. PVA dispersion is added to putty, concrete and plaster solutions to increase the strength and watertightness 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 glue PVA can be cleaned with warm soapy water.
- The 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 PVA glue is suitable for gluing wood, it is also suitable for gluing paper or cardboard.
- Glue PVA cannot be frozen. When freezing, the adhesive structure breaks down and the glue loses its adhesive properties.
- It takes 24 hours to reach the full strength of the adhesive joints.
