Hot melt Bimelt PA4884BB on the base of polyolefin

Latest-generation hot melt PA4884BB is is a very popular adhesive in modern bookbinding practices and arguably the most popular adhesive that exists on the market today.

Depending on substrates, this product can allow bonds with heat resistance up to +70 °C and cold resistance down to -25 °C. It is characterized by: good hot tack, long open time and short setting time, improved adhesion properties and excellent thermal stability that allow to reduce the consumption at least 50%, depending on application, in comparison with other adhesives.

This product compared to EVA adhesive has an improved thermal stability, stays constant in its viscosity, therefore no changes in the adhesion and in the processing quality, even after long resting time in the adhesive melting machines.  Resistant to vescosity change resulting in clean machining hour after hour.

Properties of hot melt adhesive:

  • Quick tack, even when hot;
  • Versability. Good adhesion to difficult substrates;
  • High resistance to heat;
  • Very high thermal stability;
  • High Cohesion, even when hot;
  • Good adhesion to difficult substrates;
  • Low consumption adhesive, with extremely low density;
  • Clean machining, no stringing and failing;
  • Odour and smoke-free;
  • Not-toxic;
  • Long storage life;
  • Convenience of storage.

Application: can be used in the nozzle, roller or another applicator system. Temperatures above 190 °C should be avoided. The equipment needs to be freed from EVA hot melt and cleaned since this product is not compatible with EVA-based hot melts. During extended machine stops it is recommended to switch off the heating.

Storage conditions: glue should be stored in a closed original package under normal cool and dry storage conditions and protected from direct sunlight. In such conditions glue can be stored for at least 24 months without negative impact on its quality.
