Highly reactive primary amino groups enable strong covalent bonding with substrates such as epoxy resins, polyurethanes, and acrylics.
Excellent compatibility with organic polymers and water-based systems, facilitating uniform dispersion without phase separation.
Imparts superior surface softness, slip, and anti-static properties to finished materials.
Thermally stable up to 200 °C, retaining functionality during standard polymer processing conditions.
Low volatility and non-yellowing performance, supporting long-term stability in sensitive applications like coatings and adhesives.
Surface modifier for high-performance epoxy and polyurethane coatings and sealants.
Adhesion promoter in automotive and aerospace composite bonding systems.
Softening and conditioning agent in textile finishing formulations.
Reactive additive for silicone-modified acrylic emulsions used in architectural paints.
Functional component in thermoset molding compounds requiring enhanced filler-matrix interaction.
