Silicone coating additives/Silicone resin modifier SL-4749

Due to its high surface activity, the additive accumulates on the surface of the coating where, on account of its OH reactivity, it can be integrated in the polymer network by reacting with suitable binders. If the additives are fixed to the coating surface via its reactive group, the properties, which are caused by the use of the additive, are maintained for a long period of time.

In a multitude of coating systems, SL-4749 increase the hydrophobic and oleophobic properties, which can significantly improve the water-and oil-repelling behavior. Moreover, it brings about a reduced dirt adhesion with a simultaneously increased easy-to-clean effect. The additive increases substrate wetting, leveling, surface slip, water resistance (blush resistance), anti-blocking properties and weather resistance. Therefore, we recommend that SL-4749 is initially evaluated in the formulation without using other surface additives. If additional leveling is required, leveling additives can be added in a second step. SL-4749 can also be used to improve anti-graffiti and tape release properties and organosilicone properties.
