In terms of its physical characteristics, it is typically available as a colorless or yellowish transparent liquid, though it possesses a melting point of 99°C, indicating its potential to solidify under certain conditions or in its highly purified form. Key physical properties include a density of 1.13, a boiling point of 493.2°C, and a flash point of 211.7°C. Its refractive index is approximately 1.576. Our product consistently meets a purity specification of ≥97.0% (GC), ensuring its reliability and effectiveness for demanding applications.

The versatility of TMTPS is evident in its extensive range of applications, particularly as a multifunctional silane agent. It excels as a Silane Coupling Agent, significantly improving the interfacial adhesion between organic polymers and inorganic substrates, leading to enhanced mechanical properties and durability. As a Silane Adhesion Promoter, it reinforces bonding in various composite materials and coatings. Furthermore, it functions effectively as a Silane Hydrophobing Agent, imparting water-repellent properties to surfaces, and as a Silane Dispersing Agent, facilitating the uniform distribution of pigments and fillers. Its roles extend to being a Silane Crosslinking Agent for polymer networks and a Silane Moisture Scavenger, crucial for protecting moisture-sensitive formulations.

Beyond its roles as primary silane agents, TMTPS finds application in several specialized areas. It acts as a Polypropylene Catalyst "Donor" Silane, influencing the stereoregularity of polypropylene production. It is also valued as a Silicate Stabilizer and a Polyurethane Endcapper Silane, contributing to the stability and performance of these polymer systems. Additional uses include serving as a Silane Drying Agent, Curing Agent, and Reinforcer. Its utility as a Silylating Agent, Reducing Agent, and a fundamental component in Silyl Building Blocks and Synthons underscores its importance in organic synthesis and material innovation. Moreover, it is a key reactant for the synthesis of ethylhydrosilicone fluids, broadening its industrial footprint.

TMTPS also sees widespread use in consumer-facing products due to its beneficial properties. It is incorporated into cosmetics and deodorants for its film-forming and skin-conditioning attributes. Its ability to create water-repellent surfaces makes it ideal for use in water repelling windshield coatings, improving visibility and safety. Additionally, it is found in certain food additives and various types of soaps, showcasing its non-toxic profile and broad applicability. Its capacity to enhance product stability, adhesion, and surface modification makes it a valuable asset across diverse markets.
