Expancel WE is a brilliant cost-saving, weight-reducing lightweight filler for a number of industries where these objectives need to be met. Used in waterborne products, the tiny spherical particles of Expancel WE (20μm - 55μm) will allow for a higher PVC (pigment volume concentration) with less binder requirements. The high solar reflectance of the microspheres helps cool roof coatings decrease roof temperatures, lessening the need for air con. While it achieves incredible filling capacity for upgrading genuine or artificial leather.

Product-enhancing benefits of Expancel WE

  • Reduces weight and improves application in paint and crack fillers
  • High solar reflectance and increases thermal insulation
  • Reduces shrinkage
  • Achieves better leather upgrades compared to conventional methods
  • Saves costs on binder/resin
