Special APOA Hot Melt Adhesive

Sprayshop® Special APOA Hot Melt Adhesive is a high quality unfilled polyolefine hot melt adhesive for profile wrapping decorative foils to cores made of MDF, chipboard and solid wood.

The product has a low viscosity and is therefore particularly suited for light weight and difficult to apply paper foils. It has a short open time and excellent wetting properties.

Directions of Use

  • Product must be applied in a uniform and continuous coat, with a glue thickness that is suitable for the materials to be bonded.
  • Porous substrates require a higher glue coat, whilst thin material requires a lower coat to avoid telegraphing problems on the surface to the foil.
  • To avoid irregular glue spread, and consequently bonding defects, regular checks should be made to ensure the glue roller is perfectly aligned.
  • The quantity of the glue spread will regulate the open time of the adhesive - the higher the spread of the glue the longer the open time, and vice versa.
  • The track speed should not normally be lower than 20 m/min. Low speeds may cause bonding problems due to the cooling of the adhesive.
  • If slower speeds are required, use a heavier glue spread to increase the open time. The use of hot air blowers on the glue line will also improve the wettability of the adhesive.
