Aminopropyl terminated polydimethylsiloxane is widely used in the formulation of adhesives and sealants due to its excellent adhesion properties. It enhances the bonding strength of materials, especially on surfaces that are typically difficult to adhere to, such as plastics and metals.

In the coatings industry, it serves as a key component in creating durable and flexible protective layers. Its incorporation improves the resistance of coatings to environmental factors like UV radiation, moisture, and temperature fluctuations, making it ideal for outdoor applications.

This chemical is also utilized in the production of silicone-based elastomers, where it imparts superior mechanical properties, including elasticity and thermal stability. These elastomers are commonly found in automotive parts, medical devices, and industrial gaskets.

Additionally, it plays a significant role in the modification of surfaces to enhance hydrophobicity or hydrophilicity, depending on the desired application. This makes it valuable in industries ranging from textiles to electronics, where surface properties are critical for performance.

In personal care products, it is used to improve the texture and spreadability of formulations, providing a smooth and silky feel to creams, lotions, and hair care products. Its compatibility with various ingredients makes it a versatile additive in cosmetic chemistry.
