ALCON TRANSPARENT SILICONE (MSDS)  
 

ALCON UNIVERSAL ACETOXY RTV SILICONE (TDS) 
 

Features

• Does not crack or shrink; highly durable and remains elastic at all times.
• Maintains its functionality at extremely high and low temperatures.
• Adheres strongly to common construction materials such as steel, tiles, glass, ceramics, painted wood, polyester, and more.
• Dries quickly and becomes waterproof within hours after application.
• Has 20% movement capability, making it suitable for use in flexible joints.
• Resistant to UV rays, weather conditions, and wear, making it ideal for both indoor and outdoor applications.

Application Instructions

Surface Preparation

• The surfaces in contact with the silicone must be clean and dry, free of oil, dust, rust, and loose particles.
• Non-porous surfaces should be cleaned with a suitable solvent, and any solvent applied should be wiped off before it evaporates.
• Applying masking tape to the joints prevents staining and ensures precise application. The tape should be removed immediately after application.
• A primer is not required for non-porous surfaces such as tiles, ceramics, and glass.
• A primer may be needed for certain types of metal and plastic surfaces.

Application Method

1. Cut the tip of the cartridge and screw on the application nozzle.
2. Cut the nozzle at an appropriate angle and size depending on the joint thickness.
3. Place the cartridge into a silicone gun and apply.
4. Smooth the silicone within 5 minutes of application, preferably using your fingers, a thin plastic/wooden tool, or a dry spatula before it forms a skin.
5. Clean any excess silicone immediately with a solvent, as cured silicone can only be removed mechanically.

Application Areas

• Bathtubs, shower cabins, sinks, tiles, kitchen and bathroom countertops.
• Window panes, door frames, joineries, and movable metal and plastic construction elements.
• General-purpose joint sealing works.
• Prefabricated structures.

Warnings

• Should not be used on mirrors or sensitive metals (e.g., lead, copper, brass, silver) due to acid release.
• Not suitable for natural stone and concrete surfaces.
• Adhesion loss may occur over time on surfaces that leach oil, solvents, or plasticizers.
• Not recommended for applications that will remain submerged in water.
• Should not be used on surfaces in direct contact with food or drinking water.
• Silicone sealants cannot be painted; therefore, avoid applying them to joints where painting is intended.
