CEMEDINE SX-001E Modified Silicone Sealant for Industrial Sealing

CEMEDINE SX-001E Modified Silicone Sealant is a one-component, moisture-curing industrial sealant developed for applications requiring non-sag dispensing, rapid surface curing, and durable elastic protection. Its highly thixotropic formulation allows the material to remain in place when applied to vertical surfaces, complex joints, and components where conventional liquid sealants may flow or drip. CEMEDINE currently presents SX-001E as a development product associated with EV and battery manufacturing solutions.

After exposure to atmospheric moisture, the white sealant begins forming a protective surface film within minutes and eventually cures into a rubber-like elastomer. This flexible cured layer can absorb vibration, impact, thermal expansion, contraction, and movement between dissimilar materials. It is therefore suitable for bonding and sealing structures made from materials with different coefficients of thermal expansion.

Key Benefits of CEMEDINE SX-001E Modified Silicone Sealant

CEMEDINE SX-001E Modified Silicone Sealant offers significantly higher thixotropy than conventional products in the SX series. This non-sag behavior makes it practical for vertical seams, raised beads, side-wall joints, battery housings, covers, and complicated three-dimensional geometries. Its typical viscosity is approximately 280 Pa·s, with an SVI value of 6.1 and a density of about 1.58 g/cm³.

The formulation is siloxane-free, meaning it does not contain the siloxanes associated with electrical contact failures. This characteristic makes it particularly valuable for electrical, electronic, battery, and electromechanical assemblies where material cleanliness and contact reliability are important. The liquid-applied format also provides design flexibility because it can fill irregular joint shapes before curing into a durable elastic seal.

Published development data identifies a typical tack-free time of approximately eight minutes and a deep-curing rate of about 2.1 mm per 24 hours. Once cured, the material has a typical Shore A hardness of 62, break strength of approximately 1.9 MPa, and elongation of about 130%. These properties provide a useful combination of firmness, mechanical durability, and flexibility.

Applications of CEMEDINE SX-001E Modified Silicone Sealant

CEMEDINE SX-001E Modified Silicone Sealant is designed for bonding and sealing applications in EV batteries, battery packs, electrical enclosures, industrial housings, covers, modules, and related manufactured components. Its high thixotropy supports precise bead placement on vertical surfaces, while its elastic cure helps protect joints exposed to vibration and repeated temperature changes.

The rapidly developing surface film provides early resistance to water and pressure before the sealant has completely cured. This feature may help protect partially assembled components during manufacturing, handling, testing, or temporary environmental exposure. Final performance depends on bead dimensions, substrate type, temperature, humidity, surface condition, and cure time, so production testing should be completed using representative parts.

How to Apply CEMEDINE SX-001E Modified Silicone Sealant

Before applying CEMEDINE SX-001E Modified Silicone Sealant, remove oil, grease, dust, moisture, oxide, release agents, flux residue, and loose contamination from all surfaces. Dispense a continuous bead into the required joint and confirm that the sealant makes complete contact with both sides of the bonding area. Its non-sag consistency helps retain the intended bead profile without excessive flowing.

Assemble or tool the joint before significant surface skin formation. Because the product cures through atmospheric moisture, exposed and thinner sections normally cure faster than deeply enclosed areas. Allow adequate curing before pressure testing, thermal cycling, electrical testing, transportation, or service loading. Standardizing bead width, bead height, dispensing speed, assembly time, temperature, humidity, and inspection criteria can improve production consistency.

Storage and Validation of CEMEDINE SX-001E Modified Silicone Sealant

Store CEMEDINE SX-001E Modified Silicone Sealant in its original sealed packaging under the conditions stated in the latest CEMEDINE technical and safety documentation. Protect opened material from atmospheric moisture, keep dispensing equipment clean, and use suitable workplace ventilation and personal protective equipment.

Because CEMEDINE currently identifies SX-001E as a development product, specifications, packaging, commercial availability, and recommended processing conditions should be confirmed directly with the manufacturer or an authorized supplier before production approval. For industrial users seeking a fast-skinning, siloxane-free, non-sag material, CEMEDINE SX-001E Modified Silicone Sealant provides a promising solution for EV batteries, vertical joints, dissimilar-material assemblies, and demanding industrial sealing.
