Sealant‑adhesive Sika SIKAFLEX‑112 Crystal Clear, 290 ml, transparent

Sika SIKAFLEX‑112 Crystal Clear is a one-component, transparent sealant‑adhesive supplied in a 290 ml cartridge. Formulated to cure to a clear, non‑yellowing elastomeric joint, it is intended for applications where an invisible or discreet bond and seal is required. The product offers good adhesion to a wide range of materials used in interior and exterior glazing details, frames, fittings and minor repair work where a transparent finish is essential.

Advantages

The sealant cures to a clear, elastic joint that resists yellowing and maintains transparency over time. As a one‑component formulation it is ready to use without mixing, simplifying application from the cartridge. It provides reliable adhesion to many common substrates found in glazing and trim work and allows for limited movement in bonded joints while retaining a neat, unobtrusive appearance.

Suitable for

• Transparent glazing seals and edge bonding
• Sealing clear joints on frames and fittings
• Discreet repairs where an invisible finish is needed
• Interior and exterior trim sealing where transparency is required

Key specifications

• Form: one‑component elastomeric sealant‑adhesive
• Colour: transparent, designed for non‑yellowing finish
• Packaging: 290 ml cartridge
• Curing: moisture‑curing to an elastic seal
• Movement capability: accommodates limited joint movement
• Application temperature range: suitable for common indoor and outdoor conditions (see technical data sheet for exact limits)

How to use

Surfaces must be clean, dry and free from dust, grease and loose material prior to application. Cut the cartridge nozzle to the required bead size, fit into a standard sealant gun and apply an even bead into the joint or onto the bonding surface. Tool the joint immediately to ensure contact and a smooth finish. Allow the sealant to cure by exposure to moisture; curing time depends on bead size, ambient temperature and humidity. For best results, follow the manufacturer’s detailed instructions and safety recommendations.

Usage recommendations

Test adhesion on unfamiliar substrates and use appropriate primers if necessary. Avoid application at very low temperatures or on wet surfaces. For structural bonding or where high mechanical load is expected, consult technical documentation to confirm suitability. Store cartridges in a cool, dry place and use within the shelf life stated by the manufacturer.
