BYK-070 is a silicone- and polymer-based defoamer and air release agent designed for adhesives, sealants, and ambient-curing acrylic systems. It effectively reduces foam and improves the flow and leveling properties of formulations. This liquid defoamer is compatible with a wide range of solvents including ethylbenzene, toluene, xylene, butyl acetate, and 1-methoxy-2-propyl acetate, making it suitable for diverse applications.

Product Application

Adhesives & Sealants
Special Features and Benefi ts
Prevents foam and bubble formation during manufacturing and application.


Recommended Use
Especially recommended for systems on acrylic resin basis.


Recommended Levels
0.3-1 % additive (as supplied) based upon total formulation. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.


Incorporation and Processing Instructions
Incorporate into resin before adding the other components.

Ambient Curing Systems
Special Features and Benefi ts
Prevents foam and bubble formation during manufacturing and application.


Recommended Use
Recommended for ambient curing acrylic resins (syrup).


Recommended Levels
0.5-1 % additive (as supplied) based upon syrup. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.


Incorporation and Processing Instructions
Incorporate into resin before adding the other components.
