CEMEDINE SX720W Flame-Retardant Elastic Adhesive for Electronic Component Bonding and Sealing
CEMEDINE SX720W Flame-Retardant Elastic Adhesive for Electronic Component Protection
CEMEDINE SX720W Flame-Retardant Elastic Adhesive is a one-component, moisture-curing bonding and sealing material developed for electrical and electronic assemblies. The white paste cures at room temperature and forms a durable elastic layer that can accommodate vibration, thermal expansion, contraction, and movement between joined components. Its paste consistency supports controlled dispensing around circuit boards, coils, condensers, connectors, and compact electronic parts where accurate placement and clean workmanship are important.
Created for professional manufacturing and maintenance, CEMEDINE SX720W Flame-Retardant Elastic Adhesive combines fast initial adhesion with broad bonding capability across metals, plastics, ceramics, and other compatible substrates. The solvent-free formula simplifies workplace handling because no separate mixing is required and no solvent evaporation stage is needed before curing. This makes it suitable for manual application, automated dispensing, production-line assembly, and repair operations where process efficiency and consistent sealing quality are essential.
Key Benefits of CEMEDINE SX720W Flame-Retardant Elastic Adhesive
CEMEDINE SX720W Flame-Retardant Elastic Adhesive is UL94 V-0 listed and is designed for electronic applications where flame-retardant performance is required. It also avoids halogen-based materials, antimony oxide, and phosphorus-based materials. In addition, the formulation does not contain low-molecular-weight cyclic siloxanes from D3 to D10, making it suitable for production processes that specify siloxane-free materials.
The product is supplied as a white paste with a typical viscosity of approximately 42 Pa·s at 23°C and a specific gravity of about 1.59. Its typical skin-over time is around nine minutes at 23°C, supporting practical assembly time while allowing the exposed surface to begin curing quickly. Published product data also lists a Shore A hardness of approximately 78 after cure, reflecting a firm but elastic material suitable for component fixing and protective sealing.
Applications for CEMEDINE SX720W Flame-Retardant Elastic Adhesive
CEMEDINE SX720W Flame-Retardant Elastic Adhesive is recommended for fixing circuit-board components such as condensers and coils. It can also be used for insulating seals around power supplies and transformers, as well as waterproof sealing of electronic components. The elastic cured layer helps absorb movement and vibration that could otherwise place stress on delicate parts, solder joints, or mixed-material interfaces.
Its broad adhesion range makes the product useful when electronic assemblies contain combinations of aluminum, steel, polycarbonate, PVC, nylon, ABS, polystyrene, and other compatible materials. Actual bond strength depends on the substrate grade, surface coating, contamination level, joint design, adhesive thickness, temperature, and humidity. Manufacturers should therefore complete representative adhesion and durability tests before approving the product for mass production or critical equipment.
How to Apply CEMEDINE SX720W Flame-Retardant Elastic Adhesive
Before application, clean the bonding and sealing surfaces to remove oil, dust, moisture, oxidation, release agents, and other contaminants. Apply CEMEDINE SX720W Flame-Retardant Elastic Adhesive in a controlled bead or coating, then assemble or position the components within the available working period. For non-porous materials or applications requiring stronger initial holding power, double-sided application may be considered according to the production process and substrate condition.
Maintain the required alignment and avoid disturbing the assembly while the adhesive develops initial strength. Because curing depends on moisture in the air, temperature, humidity, bead size, and joint depth can affect the curing rate. Allow adequate curing before electrical testing, waterproof evaluation, vibration exposure, thermal cycling, packaging, or shipment.
Storage and Safety of CEMEDINE SX720W Flame-Retardant Elastic Adhesive
Store CEMEDINE SX720W Flame-Retardant Elastic Adhesive in its original sealed package under the conditions stated on the current product label and technical documentation. Keep the dispensing outlet clean and close the container immediately after use to limit moisture exposure. Operators should work in a ventilated area, avoid skin and eye contact, and follow the latest safety data sheet.
For electronics manufacturers seeking a flame-retardant, solvent-free, and siloxane-free solution, CEMEDINE SX720W Flame-Retardant Elastic Adhesive provides reliable component fixing, insulation sealing, and waterproof protection. Its one-part processing, quick initial adhesion, durable elasticity, and electronic-grade design make it a practical choice for circuit boards, power supplies, transformers, and related assemblies.
