At JEC World 2026, Elkem presents 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.

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™ ESA 8352 A&B withstands continuous temperatures up to 180°C, with peaks up to 220°C, helping ensure long‑term reliability and reduced maintenance.

By supporting easy mixing and dispensing - whether manual or automated - the adhesive integrates smoothly into modern production lines, contributing to consistent quality and reduced defects.

BLUESIL™ ESA 8352 A&B was developed to address the growing demand for high‑temperature, flexible silicone adhesives 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.

At JEC World 2026, composite manufacturers, equipment suppliers and industrial partners will have the opportunity to:

• Explore Elkem’s silicone expertise for composites and industrial assembly

• Discuss real‑world applications with Elkem technical and market experts

• Learn how silicone solutions can contribute to performance, durability and more sustainable manufacturing.
