DefoamersDefoamers
Defoamer should have limited solubility (incompatibility)in the coating and side effects such as crater formation.
Lower surface tension.Works through direct destruction of macro foam at theair interface and by avoiding major air entrapment.

destabilization of lamella.4 Destabilization leads to the rupture of the lamella4. Destabilization leads to the rupture of the lamella.
Mechanism of Defoaming
Coalescence of micro bubbles
Deaerators (non polar) are oriented in such a way tosurround the air bubbles.
These bubbles come together and fuse to form bigger airbubbles. Fusion takes place because of the reducedinteraction of deaerator and binderinteraction of deaerator and binder.
At this moment coalescence takes place and leads to thebigger bubble formation.gg
Stoke’s law – Bigger air bubbles moves with higher velocity than small bubbles.

RheologyRheology
Rh l i th t d f fl d d f tiRheology is the study of flow and deformation
of materials under applied forcesof materials under applied forces
• When a force is applied to a liquid, the liquid will
flow to relieve the strain from this force
• Different systems will resist this flow differently from
other and the measurement of the resistance of theother and the measurement of the resistance of the
system is the measure of viscosity of the system
