In terms of selecting the most appropriate silicone fluid for industrial, cosmetic, or specialty applications, the two leading names are Wacker and Dowsil. Both brands possess decades of chemistry experience; however, the confusion arises when buyers in India have to choose between these brands considering price, availability, and technical compatibility. The purpose of this guide is to provide essential information about what to look for before making a purchasing decision.
What Are Silicone Fluids and Uses?
The chemical structure of silicone fluids is polydimethylsiloxane (PDMS) which is colourless, odourless, and has excellent thermal stability. Common uses of silicone fluids are for:
- Textile & leather finishing - provide softness and water resistance
- Cosmetic and Personal Care Products – Used as emollients and spreadability agents
- Electrical and Electronics – Used as dielectric fluids and heat dissipation fluids
- Automotive and Industrial – Used as lubricating agents, damping fluids, and release agents
- Pharmaceuticals – Used as antifoam agents and excipients
The viscosity & grade of silicone fluid will affect your final product's performance based on its use. Thus, it is very important to understand what separates the best from the rest when comparing brands of silicone fluids.
