Warning
- Do not use a dc voltage with either SPD or LC SmartGlass’. If you use a dc voltage, the SmartGlass will not function properly and the dc voltage may polarize the particles. Initially they will let light through but gradually the particles will migrate toward one end of the cell and cluster or pile on top of each other. This leads to a gradual darkening of the glass. The only way to avoid this unwanted darkening is to use an ac voltage. With an ac voltage, the tendency to migrate toward either end of the cell is neutralized.
- Only neutral cure non acetic silicone should be used when installing SmartGlass. We can supply the required silicone to ensure the safety and longevity of your purchase.
