Hydrophilic silica and hydrophobic silica in epoxy resin Fired silica is stirred and mixed into the epoxy resin with a dissolver. The hydrophilic silica (right) mixes faster than the hydrophobic silica (left).

BYK's wetting and dispersing agents create a finely and uniformly dispersed state of solid particles in the liquid, achieving long-term stabilization of the system. The additives stabilize pigments (inorganic, organic, and pearlescent pigments) and fillers. The liquid phase consists of water and various organic solvents with different polarities.
