KONISHI SL220LB Low-Viscosity Elastic Adhesive for Electronic Component Bonding and Sealing

KONISHI SL220LB Low-Viscosity Elastic Adhesive Benefits

KONISHI SL220LB Low-Viscosity Elastic Adhesive combines controlled flow with elastic cured performance. Compared with higher-viscosity SL220 grades, its 15 to 30 Pa·s viscosity range at 23°C supports easier dispensing through smaller nozzles and improved penetration around compact components. The ready-to-use format eliminates weighing and mixing, helping reduce preparation time, process variation, and material waste.

The formulation does not use tin compounds and belongs to the KONISHI SL/FB electronic adhesive series designed for fast curing, shock resistance, solvent-free processing, and reliable adhesion to different substrates. After curing, the elastic bond helps distribute stress created by vibration, impact, thermal cycling, and differences in expansion between joined materials. The black paste also provides clear visual contrast during application and suits dark housings or electronic modules.

Applications for KONISHI SL220LB Low-Viscosity Elastic Adhesive

This product can be used for fixing, bonding, filling, and sealing electrical or electronic parts. Typical applications include PCB components, sensors, connectors, small motors, camera modules, display assemblies, speakers, appliance electronics, automotive modules, and industrial control devices. Its controlled low-viscosity flow is useful around closely spaced parts, narrow joints, cable entries, and irregular component geometries.

The adhesive can bond compatible stainless steel, ABS, polycarbonate, and other rigid materials after suitable surface preparation. It is especially useful for dissimilar-material assemblies that experience shock, vibration, or repeated temperature changes. Because plastic grades, coatings, mold-release agents, and surface treatments vary, manufacturers should complete adhesion and compatibility tests using actual production parts before commercial approval.

KONISHI SL220LB Low-Viscosity Elastic Adhesive Properties

Published typical values include a specific gravity of 1.10 to 1.20 and a skinning time of approximately four to nine minutes at 23°C and 50% relative humidity. Representative tensile lap-shear strength is about 3.4 N/mm² on stainless steel, 2.8 N/mm² on ABS, and 2.7 N/mm² on polycarbonate. The cured material has a Type A durometer hardness near 48, maximum tensile stress around 5.5 N/mm², and elongation at break of approximately 300%.

Typical electrical data include volume resistivity of 1.3 × 10¹² Ω·cm, thermal conductivity of 0.20 W/m·K, dielectric constant of 4.75 at 1 MHz, and dielectric dissipation factor of 0.044. These values are technical references rather than guaranteed purchasing specifications and may vary with curing conditions, adhesive thickness, surface preparation, and test method.

How to Apply KONISHI SL220LB Low-Viscosity Elastic Adhesive

Clean every bonding surface and remove oil, dust, moisture, oxidation, flux residue, and mold-release contamination. Apply a controlled dot or bead to one substrate, assemble the parts promptly, and fixture them when movement is possible. Ensure atmospheric moisture can reach the adhesive because curing progresses from exposed surfaces inward.

Validate nozzle diameter, dispensing pressure, adhesive volume, bond-line thickness, skin time, handling time, and full-cure performance under actual production conditions. Close the package immediately after use to reduce moisture exposure. Standard packaging includes 120 ml tubes and 333 ml cartridges, supporting maintenance, prototyping, manual dispensing, and regular manufacturing.
