Application Fields
The aqueous solutions of BIOLAY 100 can be applied with all standard coating equipments such as film press, size press, blade coater or curtain coater. Depending on the application method and the required viscosity, we recommend to prepare the following solutions:- Brookfield viscosity <50 mPas (RT, 100 rpm): 5 % solution
- Brookfield viscosity max. 150 mPas (RT, 100 rpm): 10 % solution
- Brookfield viscosity max. 600 mPas (RT, 100 rpm): 18 % solution
- Recommendation for Use
Preparing aqueous solutions of BIOLAY 100
BIOLAY 100 is water soluble and solutions of up to 20 % can be easily prepared. However, the following requirements need to be met:
- First, place the water in the respective vessel and subsequently add the appropriate amount of BIOLAY 100. The slower the addition of the powder the easier it can be dissolved.
- Vigorous stirring or a make-down unit substantially facilitate the dissolving process.
- Higher temperatures (maximum 60 °C) accelerate the dissolving process and reduce the viscosity.
Appearance of aqueous solutions
The aqueous solutions of BIOLAY 100 have an amber color. This color originiates from insoluble constituents of the natural raw material. They cannot be removed during the production process of the powder product. These insoluble constituents precipitate over time, especially in low viscosity solutions (<5 %).
Stability of aqueous solutions
BIOLAY 100 does not contain any preservatives. While the powder product is stable for 12 months under dry storing conditions, the aqueous solutions have a limited shelf life.
If the aqueous solutions need to be stored for longer periods, we recommend the use of preservatives.Formulation recommendations
The solutions of BIOLAY 100 are compatible with hydrophobic additives such as synthetic (e. g. AKD) or natural waxes (e. g. CHT-COAT WAX E-7080 or CHT-COAT WAX E-7000). We recommend the addition of wax additives for reducing the COBB value.

- Stabilities
BIOLAY 100 is stable under standard coating formulation pH values (pH 5 – 9). Extremely low (pH <3) and high pH values (pH >10) lead to decomposition of the aqueous solutions.
