SI1826 One Component RTV Electronic Silicone Adhesive Sealant

White/black/Transparent

∎Product Description

RTV 1826 alcohol-free silicone adhesive sealant is a neutral silicone sealing material that cures by absorbing moisture from the air at room temperature. It is non-corrosive to materials and exhibits excellent adhesive and sealing properties on most plastics, metals, and other materials, ensuring the stability of electronic products operating under harsh conditions.

∎Typical Applications

● Mainly for household appliance, engineering machinery, PV modules, Lithium battery pack, automotive lamps, LED lamps, PCB components fixing bonding and sealing.

∎Key Features

● Excellent chemical resistance, low odor, and strong adhesion

● Low volatile content (not exceeding 300 ppm), non-corrosive and fog-free in enclosed environments

● Resistance to moisture, contaminants, and other atmospheric components

● Reduction of mechanical stress and tension caused by mechanical, thermal shocks, and vibrations

● Outstanding outdoor aging resistance, with a service life of 20-30 years

● Stable mechanical and electrical performance within a temperature range of -60°C to 200°C

1) Surface Preparation: Clean the surfaces to be bonded or coated, removing rust, dust, grease, and other contaminants.

2) Application: Remove the cap from the tube (or cut the nozzle), then apply the adhesive evenly onto the cleaned surface. Press and fix the bonded parts together.

3) Curing: Allow the bonded or sealed parts to cure naturally in the air. Curing progresses from the surface inward. Under room temperature (23°C) and 55% relative humidity, the adhesive will cure to a depth of 3–4 mm within 24 hours. For deeper applications—especially in areas with limited air exposure—full curing may take longer. At lower temperatures, curing time will also extend. For a 1 cm thick sealant, full curing may require more than 3 days.

∎Precautions

* After use, immediately tighten the cap and store the remaining adhesive in a sealed condition.

* If a slight skin forms at the nozzle before reuse, simply remove it—this does not affect performance.

* During storage, minor curing may occur at the tube opening. Remove the cured material before use; this does not impact the product's effectiveness.
