Defoamers, both liquid and in powder form, perform three main roles:

1. They destroy air bubbles already during the mixing phase

2. They fragment the bubbles into smaller air bubbles

3. They foster the air release

The defoamers of Pentachem perform these roles with great success and offer the following advantages:

  • They increase the mechanical strengths
  • They increase the resistance to abrasion
  • They increase the density of the admixtures
  • They have extremely low VOC emissions (Antifoam PS 201)
  • They allow the final product to show a smooth surface without defects, craters, or stains
