Waterborne general leveling agent LD-91082
Waterborne general Leveling Agent LD-91082
(Similar to BYK-333and TEGO-450)
First, summary
The product is a kind of high viscosity polyether modification organic polysiloxane, belonging to a new type silicone surfactant (long-chain alkyl and polyether modified silicone oil). It possesses a character of low surface tension. It applies to waterborne, solvent and solventless ink and ink system. And it has an excellent intersolubility with alkanes oiliness material and polymer film forming matter. The product has many performance like flow defoaming, emulsification, percolation, antistatic electricity, soft, lubrication, moisture retention and solubility enhancement. It has a good leveling effect in waterborne coatings. What’s more, it also has best compatibility, best breaking oil point, and can lower the skin-friction force effectively. It can prevent pinhole and not affect the overcoatability. The effect is good.

Third, product application
1. It can improve wettability and exhibition cloth performance of pigments or fillers in the system. So it increases the compatibility and dispersion between fillers and liquid to make coatings smoother and steadier.
2. It can make the surface more smooth and improve the wettability of the substrate, as well as the flow-spreading property, surface smoothness of ink, improving the glossiness of the product and preventing shrinkage cavity.
3. Defoaming, oil shrinkage prevention, floating color prevention and flowering prevention. Addition amount for reference: 0.05-0.3%
4. If in solvent-free system, the effect is the same as above. It is very effective on increasing the wetting of the substrate and strengthening the seepage force and combination with base. Addition amount for reference: 0.3-1%.
Fourth, package
25kg plastic bucket, 50kg metal pail, 200kg plastic bucket, 200kg metal pail or according to customers’ requirements
Fifth, storage and transportation
Products should be stored sealed and kept in a shady, cool and dried place. Shelf life: 12 months (non-dangerous products)
