Shin-Etsu KE-1820 Heat-Cure Silicone Adhesive Sealant

Description

Shin-Etsu KE-1820 Adhesive Sealant is a one-component, heat-cure thixotropic silicone for bonding and sealing metals, plastics, glass, and ceramics. KE-1820 silicone gives electronics and assembly teams a stable paste that holds position before heat cure and keeps a 30 day pot life at room temperature.

KE-1820 silicone Benefits

• One-component format removes mix ratio checks and reduces bench setup time.
• Thixotropic paste helps the bead stay placed on vertical seams, housings, and gasket paths.
• Heat-cure chemistry supports durable elastomer formation after the part is positioned.
• Unprimed adhesion to common metals, plastics, glass, and ceramics helps simplify material trials.
• Room-temperature stability gives teams a practical handling window before cure.

This grade fits production work where a room-temperature RTV is not the right process and the assembly can tolerate a heat-cure step. Use it for small housings, electronics, form-in-place gaskets, and sealed components that need a tough silicone elastomer after cure.

Where KE-1820 silicone Fits

• Electronics sealing where the material must stay in place before cure.
• Form-in-place gasket paths on metal or plastic housings.
• Glass, ceramic, and mixed-material assemblies that need silicone flexibility.
• Production fixtures where heat cure is already part of the process.
• Repair or prototype builds that need a long room-temperature handling window.

Surface Preparation And Use

Apply to clean, dry surfaces free of oil, dust, release agents, and loose oxide. Confirm fit on every substrate before production because mold release, plasticizer, plating, or residue can affect adhesion. Keep the bead size consistent so heat reaches the sealant evenly during cure.

Store unopened material according to the current data sheet and check shelf life before use. For related silicone bonding grades, browse Chemical Concepts silicone adhesives.
