Building on its long-standing expertise in silicone materials, Elkem will showcase two complementary solutions designed to address key challenges in composite molding and industrial assembly:
BLUESIL™ RTV 3724 A&B – A Silicone reusable vaccum bag
for composite molding
BLUESIL™ ESA 8352 A&B – A High-performance self-adhesive
silicone for demanding application
Visitors to Hall 6, booth B113 are invited to discover how these solutions help manufacturers improve process efficiency, durability and design freedom in complex environments.
Silicone solutions for advanced composite molding
At JEC World 2026, Elkem will present BLUESIL™ RTV 3724, a silicone rubber specifically developed for molding and tooling applications in the composites industry.
This RTV (room‑temperature vulcanizing) silicone elastomer is well suited for the production of flexible molds used with a wide range of resins.
It offers:
Excellent reproduction of fine details
Good mechanical strength and elasticity for repeated demolding
Reliable performance for complex geometries
Ease of processing for workshop and industrial environments
BLUESIL™ RTV 3724 supports composite manufacturers seeking consistent mold quality, reduced scrap rates and efficient production cycles.
Elkem will also highlight BLUESIL™ ESA 8352 A&B, a newly launched two‑component silicone adhesive designed for reliable bonding in complex industrial environments.
Curing at room temperature, BLUESIL™ ESA 8352 A&B combines advanced self‑bonding technology with outstanding thermal and chemical resistance. Its performance profile makes it relevant for a broader range of industrial assembly applications where durability, flexibility and process efficiency are critical.
A new silicone adhesive for demanding industrial assemblies
Key benefits include:
Primeless adhesion on multiple substrates, including metals and plastics
Room‑temperature curing, enabling energy savings and faster part handling
Handling time of approximately 25 to 30 minutes, adaptable to different assembly speeds
Excellent resistance to thermal cycling, high temperatures and chemicals
Ability to accommodate thermal expansion and complex geometries
Certified UL 94 HB for flammability resistance, #BLUESIL™ESA8352 A&B withstands continuous temperatures up to 180°C, with peaks up to 220°C, helping ensure long‑term reliability and reduced maintenance.
BLUESIL™ ESA 8352 A&B was developed to address the growing demand for high‑temperature, flexible #siliconeadhesives while offering versatility to adapt to different processing and assembly speeds. Its room‑temperature curing and strong multi‑substrate adhesion help manufacturers reduce energy use, streamline production and deliver high‑performing systems.
