Seimeda

Seimeda Overview

Seimeda is a single-component silicone building sealant made for glazing and construction joints. It is formulated to stay flexible and adhere strongly across the mixed materials that show up around a window or a glazed facade — glass, aluminium, stainless steel, ceramics, plastics and timber.

Single-component means it comes ready to use with no mixing or measuring on site, and cures on contact with moisture in the air. That matters practically: two-part sealants have to be proportioned and mixed correctly, and mixing errors are a common source of joints that never cure properly.

It is aimed at the work we do every day — installing and sealing windows and doors, glazing sunrooms, and sealing joints on smaller glazed assemblies.

Key Features & Benefits

• Single-component: ready to use straight from the cartridge, with no mixing or measuring
• Fast cure: reaches working strength quickly, which shortens the exposure window on site
• High adhesion: bonds across glass, aluminium alloy, stainless steel, ceramics, plastics and wood
• Water resistant: holds a watertight seal under sustained wetting
• Weather stable: formulated against rain, snow, ozone, temperature swings and UV exposure
• No yellowing or blackening: keeps its appearance rather than discolouring, which matters on visible joints
• Movement recovery: returns to shape after expansion and contraction, so joints keep sealing as they move
