Foaming solutions

By foaming the glue before application the volume can expand to more than 50%.

PVAc
Not all dispersions are useable at foaming, but many of them will work perfectly. We can foam PVAc dispersions to production of for example packaging, and we foam dispersions for lamination of paper foils to chipboards and MDF plates.

The saving in kilo is dramatic, and at the same time is the foamed glue extreme useable to humidify the surface by using half the consumption. An extra benefit is reduced content of water in the glue, which gives a lot of benefits under and after the production.

Hotmelt
For a lot of applications hotmelt can be foamed with dry air or nitrogen, which increases the volume of the glue at up to 60%. The process give longer open time and at the same time is the pressing time reduced when the air is pressed out of the glueline and the items are bonded.

For the PVAc dispersions and for hotmelt can we advice the correct equipment, and help for test and implementing of the glue adjusting all the parameters.
