Properties of CERAFAK 110 Wax Dispersion

2021-12-08   Pageview:157

The additive CERAFAK 110 improves the orientation of effect pigments (e.g. aluminum, mica) and enhances the trigger effect. Short-wave defects (speckles, Benard swirls) are minimized and the leveling properties of transparent coatings are improved. Settlement in the container is also reduced. Aromatic free.

 

 

 

 

 

 

 

 

 

 

 

 

 

Because these accelerators are acidic, they are prone to slight cross-linking in the tank, especially under high-temperature storage and transportation conditions, resulting in an increase in the viscosity of the coating. These can be added to prevent gelation and viscosity stabilizers (such as Deu add DVP) to balance, or to restore slightly gelled paint to a reusable level.

Compatibility among additives (offset, negative influence and addition, synergy)
The application and addition of additives may seem simple, but sometimes it is the most complicated problem, because it is easy to get the best addition amount when evaluating the individual performance of individual additives, but due to the entire formulation and subsequent The added additives may produce positive additions or synergistic effects, and may also produce negative offsetting effects. It is even necessary to face up to the side effects that it may bring after preventing or solving the problem. Therefore, the specific additive amount needs a verification of compatibility and final performance, and adjust the variety or amount of additive when necessary. The following examples illustrate the compatibility of additives, and provide reference, reference and extension for formulators when applying additives.

Offset, negative impact
General polyether modified polysiloxane leveling agent has excellent compatibility, leveling, slippery and various characteristics, but its polyether modified structure is also prone to foam stabilization problems. Therefore, when formula The polyether-modified polysiloxane leveling agent was selected in the design, and when the defoamer was selected for evaluation, the formula used was a formula without polyether-modified polysiloxane, which was only for the evaluation of the resin base material. Finally, not only the amount of addition needs to be re-evaluated, but also the type of defoamer needs to be changed. Because the foam stabilization of different modified polyether structures is different, the corresponding defoamer should be selected instead of simply increasing the amount of defoamer added. This is because the polyether modified polysiloxane leveling agent will counteract the defoaming Examples of defoaming properties of foaming agents.
