In the ever-evolving world of reactive silicone materials, optimizing performance while maintaining processability and sustainability is a constant challenge. Manufacturers of thermal interface materials (TIMs), adhesives, and coatings demand solutions that enhance filler dispersion, reduce viscosity, and improve thermal conductivity—all while staying ahead of environmental regulations.
Enter Silaplane™ FM-0815J, JNC’s latest innovation in silicone chemistry. This trimethoxy silyl-terminated PDMS is engineered to push the boundaries of silicone formulations by offering:
Key Advantages of Silaplane™ FM-0815J
✅ Ultra-High Filler Loading – Designed to stabilize inorganic filler dispersions, FM-0815J allows manufacturers to significantly increase the filler-to-polymer ratio. This is crucial for thermal interface materials, where high filler content directly correlates with improved thermal conductivity.
✅ Enhanced Viscosity Control – Unlike traditional silane coupling agents, FM-0815J chemically bonds to fillers, effectively reducing viscosity while ensuring a stable and homogenous dispersion. This results in improved processability and consistency in manufacturing.
✅ PFAS-Free Alternative – With increasing regulatory scrutiny on PFAS and fluorine-containing materials, FM-0815J provides a high-performance, environmentally conscious alternative that matches or exceeds the capabilities of F-containing systems. With a water contact angle of 100°—equivalent to fluorinated treatments—it delivers exceptional water and oil repellency without environmental trade-offs.
✅ Superior Filler Adsorption – The alkoxysilyl groups of FM-0815J form strong chemisorption bonds with filler surfaces, preventing aggregation and ensuring long-term stability in the final formulation. This is particularly beneficial for epoxies, polyurethanes, and silicone oils, where optimal dispersion directly impacts performance.
The hydroxy groups of SilaplaneTM physically adsorb to the filler by hydrophilic interaction with the hydroxy groups on the filler surface.
The alkoxysilyl groups of FM-0815J chemically bond to the hydroxy groups on the filler surface, resulting in strong chemisorption to the filler.
Why PFAS-Free Matters
The shift away from PFAS is more than a trend; it’s a necessity. These “forever chemicals” have been prized for their durability and repellency but come with significant environmental and health concerns. Silaplane™ FM-0815J steps in as a forward-thinking solution, combining silicone’s inherent flexibility and resistance with eco-friendly design. For industries like paints, coatings, and polymers, this means anti-fouling and anti-abrasion benefits without the ecological footprint.
Why It Matters for Thermal Interface Materials (TIMs)
TIMs are critical for electronics, automotive, and industrial applications where efficient heat dissipation is necessary. Achieving high thermal conductivity without compromising processability is a key challenge.
Imagine a thermal interface material that dissipates heat more efficiently in your next-generation EV battery, or a coating that protects infrastructure with minimal environmental impact. FM-0815J’s ability to enhance filler loadings and maintain low sliding angles makes it a versatile player across sectors—medical, automotive, electronics, and beyond. Its high affinity for silicone binder resins and low impurity levels further ensure reliability and scalability, with JNC capable of mass-producing it in high volumes.
- Traditional silanes struggle with maintaining dispersion at higher filler loadings, leading to increased viscosity and processing difficulties.
- Silaplane™ FM-0815J overcomes this limitation by offering low-viscosity, high-filler compatibility, resulting in superior thermal management performance.
Whether you’re working with alumina-filled dispersions, epoxy-based TIMs, or polyurethane formulations, FM-0815J ensures reliable, scalable, and high-efficiency production.
