OCI KONASIL KD15 is an imported hydrophobic fumed silica from South Korea, produced by surface modification. It is a high-purity amorphous white powder with excellent hydrophobicity, thixotropy, anti-settling and reinforcement, designed for sealants, adhesives, coatings and moisture-resistant systems.
Excellent hydrophobicity & moisture resistance - Surface modified to resist moisture, improve water resistance and weatherability
Stable rheology & thixotropy - Precisely adjust viscosity, effectively anti-sagging and anti-settling, better workability
High-efficiency reinforcement & toughening - Greatly improve mechanical strength, adhesion and durability of elastomers
Wide system compatibility - Excellent compatibility with resins, coatings, inks and silicone rubber
Powder anti-caking & flow aid - Improve fluidity, prevent caking, easy storage and automatic processing
Water-resistant sealants & adhesives - Improve hydrophobicity and bonding, suitable for outdoor and moist environments
Industrial coatings & printing inks - Anti-settling and anti-sagging, optimize film uniformity and water resistance
HTV/RTV silicone rubber - Reinforce and toughen, provide excellent hydrophobicity and weatherability
Acrylic/PU/PVC plastisol - Rheology control, improve processability and surface quality
Resin gel coats & composites - Enhance mechanical properties, water resistance, aging resistance and insulation
