Applied on the surface coatings

OBAHS gives high and very high whiteness when applied in surface coatings with natural and synthetic binders and commercial pigments at PH ***1.The effect depends on the type and amount of co-binders such as CMC,PVA and synthetic products.

Applied at the size press

OBAHS can be incorporated in size press liquids based on solubility and/or modified starches and applied in combination with PVA,CMC and liquids containing pigments. Performance is almost not affected by the base paper PH.

PROPERTIES

Chemical construction: Triazine Stilbene Derivates (HEXA SULFA)

Appearance: Clear, yellowish to yellowish-brown liquid

Whitening intensity: **0±3 points compared with standard

Specific gravity(*5℃): About 1.1g/cm3

Storage stability: OBAHS  has good stability to storage and cold temperatures. Prolonged storage at temperatures below**0℃can result in product freezing. Frozen procuct can be restored to its original state without lost of effectiveness by leaving to stand at room temperature or heating briefly to temperatures no higher than *0℃.

SHADE

OBAHS gives a slightly reddish white in all applications. Even at high concentrations it does not green off.

ECOLOGY/TOXICOLOGY

The usual hygiene and safety rules for handling chemicals should be observed in storage, handling and use. The produc must not be swallowed.
