USES and APPLICATIONS of BYK P 105:
Byk P 105 is a solvent-free version of the BYK-P 104 additive and is specifically designed to stabilize fillers in solvent-based and solvent-free adhesives, as well as in room-temperature-curing resin systems.
The primary operating principle of Byk P 105 is the targeted, controlled flocculation of filler particles.

The additive molecules form "bridges" between individual particles, creating a stable three-dimensional network structure within the system.
This structure effectively prevents the settling of heavy fillers and prevents drips, especially when applied to vertical or inclined surfaces.
Due to its high viscosity, Byk P 105 is recommended to warm the additive before use to facilitate dosing and mixing.

Applications of Byk P 105: Industrial coatings, Construction coatings, Wood and furniture coatings, Automotive coatings, Anti-corrosion systems, and Amine-neutralized water-based coatings.

-Byk P 105 is used adhesive and sealant manufacturing.
In this industry, Byk P 105 plays a key role as a stabilizer in highly filled systems.
Byk P 105 is particularly recommended for acrylate adhesives, but can also be successfully used in polyurethane compounds.

Incorporating Byk P 105 into adhesive formulations prevents fillers (such as calcium carbonate, talc, and barite) from settling during storage, ensuring consistent product properties from batch to batch.

Furthermore, preventing sagging is important for adhesives used on vertical surfaces, ensuring a uniform adhesive joint thickness.
The recommended addition level of Byk P 105 is 0.5-1.5% of the filler weight.

-Room-temperature-curing resin systems use of Byk P 105:
In the production of polymer flooring, repair mortars, putties, and other systems based on room-temperature-curing resins (e.g., acrylate resins), BYK-P 105 is used to stabilize fillers and pigments.

Controlled flocculation prevents their settling, which is critical for systems with a long pot life, and ensures uniform properties of the cured material, such as strength and appearance.
As in adhesives, Byk P 105 helps prevent drips when applied to complex surfaces.

The optimal dosage of Byk P 105 is determined by laboratory tests and ranges from 0.5-1.5% of the filler weight.
For maximum effectiveness, Byk P 105 should be added to the system before the solid components.

-Paint and varnish industry uses of Byk P 105:
Although BYK-P 105 is primarily used in adhesives and resins, it can also be used in solvent-borne and solvent-free coatings to stabilize fillers.
