IOTA 2170 is a single-ended hydroxyl-functional silicone oil designed to balance controlled reactivity with excellent compatibility. It disperses uniformly in polyurethane and amino resin systems, ensuring long-term formulation stability and reliable processing performance.

The single hydroxyl group allows IOTA 2170 to participate moderately in resin crosslinking, introducing silicone functionality without negatively affecting rheology, leveling, or storage stability. This controlled interaction makes it particularly suitable for systems where appearance quality and processing consistency are critical.

IOTA 2170 enhances surface smoothness, soft hand feel, and overall tactile quality, while also improving weather resistance and stain resistance. It is widely used in coatings, inks, synthetic leather finishes, and mild resin modification applications, offering a practical and stable solution for surface performance enhancement.
