Application field


Liquid Paint


Features and Benefits: BYK-1788 It is a zero-emission polymer defoamer, especially suitable for 100% UV curing system with solid content, also suitable for high solid content
and solvent-free polyurethane or unsaturated polyester system. The additive does not affect the surface properties of the coating such as gloss or transparency and is therefore especially recommended for clear coats
0.3-0.5 % Adjuvant dosage (as supplied) based on total formulation.


The above recommended dosage is for reference, the optimal dosage should be determined through a series of experiments.


Joining method and processing guidance


BYK-1788 It can be added during the grinding process or added later. If post-added, a sufficiently high shear force is required to ensure that the additive is dispersed evenly.

Thermoset


Features and Benefits: Exhibits the highest efficiency in defoaming in almost all epoxy resin systems such as casting resins, vacuum infusion or winding systems. The additivealso exhibits excellent defoaming properties in acrylate and unsaturated polyester resins, providing the bestDefoaming efficiency. Used in some resins BYK-1788 can improve the surface quality and reduce the outgassing time of composite materials.


Recommended use

Epoxy resin Special recommendation
Unsaturated polyester resin Special recommendation
Acrylates Special recommendation
Polyurethane Tree Recommended

Recommended dosage


0.1-0.75 % Adjuvant dosage (as supplied) based on total formulation .


The above recommended dosage is for reference, the optimal dosage should be Determined after a series of experiments.


Joining method and processing guidance


Stir into resin before adding other ingredients.


Special Reminder


In two-component epoxy systems,BYK-1788 can be added to both resin components and amine curing in the agent component.
