Processing & Availability
- Additional product information
- The advantages of AFCONA 2524 are:
- Additional product information
- 1) Very easy to incorporate under low shear forces where it will not cause any craters and will not affect the levelling properties of the coating.
- Additional product information
- 2) Next to the good defoaming properties it also works as a good levelling agent. According to the theory adding defoamers normally will affect the levelling and adding levelling agents will cause foaming. Therefore, AFCONA 2524 is the perfect balance between defoaming and levelling. If in some cases the levelling is still not sufficient, a small amount of AFCONA -3570 or AFCONA - 3522 can be added.
