H-SILICONE Transparent

GENERALITIES:

H-Silicone TRANSPARENT is a versatile, single-component silicone sealant based on acetoxy curing technology. It cures via atmospheric humidity to form a permanently elastic, durable rubber joint with exceptional resistance to UV radiation, weathering, and aging.

Featuring 600 % elongation and a low modulus (0.3 MPa), it accommodates significant joint movement while maintaining adhesion. Excellent grip on non-porous substrates including glass, ceramics, glazed surfaces, and anodized aluminium without primer. Temperature resistance –50 °C to +120 °C after curing. Not paintable.

• High Elasticity: 600 % elongation accommodates joint movement and thermal expansion.
• UV & Weather Resistant: Permanently withstands sunlight and weathering without cracking or chalking.
• Fast Curing: Acetoxy system ensures quick skin formation (≈13 min) and reliable cure.
• Excellent Adhesion: Strong grip on glass, tiles, ceramics, varnished wood, and sanitary surfaces.

USAGE / EXAMPLE OF USE:

• Furniture Glazing: Sealing glass panels in cabinet doors, vitrines, and display cases where a clear, clean seal is required.
• Kitchen & Bathroom Joinery: Sealing joints between countertops and tiled walls, or finishing edges around sanitary fixtures set into wooden vanities.
• Shop Fitting: Assembling glass structures, sealing aluminium profile connections, and general glass-to-glass sealing in retail displays.
• Construction Glazing: Standard glazing of windows and door frames, sealing glass blocks, and weatherproofing of non-porous building elements.
• Workshop Maintenance: General sealing of gaps and cracks in ceramics, glass, or coated metal parts.

TECHNICAL DATA & SUITABLE WORKING CONDITIONS:

APPLICATION / HANDLING:

The substrate must be clean, firm, and free of loose particles, dust, grease, and oil.

INSTRUCTIONS:

Cut the cartridge tip and attach the nozzle. Cut the nozzle to the desired bead width.

Apply the silicone using a mechanical or pneumatic caulking gun.

Tool the sealant immediately (within approx. 10 minutes) using a spatula dipped in soapy water to ensure good contact with the joint walls and a smooth finish.

Remove masking tape immediately after tooling.

NOTE:

Acetoxy silicones release acetic acid during curing (vinegar smell). Do not use on alkaline substrates (concrete, mortar, plaster, marble), corrodible metals (lead, copper, zinc, galvanized steel, aluminium), or mirrors (may attack the backing). Also not suitable for PE, PP, Teflon, PMMA, ABS, polycarbonate, or bituminous substrates. For sealing acrylic bathtubs, use only neutral silicones (e.g., H-Silicone Mirror).

JOINT DIMENSIONS:

Minimum width 4 mm, maximum width 25 mm. Ideal joint width-to-depth ratio is 2:1.

LIMITATIONS:

Not suitable for use on PE, PP, Teflon, PMMA, ABS, polycarbonate, concrete, marble, aluminium, copper and galvanized sheet, lead, galvanically coated steel, mirrors, or bituminous substrates. For acrylic bathtubs, use neutral silicone only.

CLEANING:

Uncured material should be removed immediately using Hraniclean 01. Cured silicone can only be removed mechanically. Hands should be washed with soap and water; a restorative hand cream is recommended.

PRECAUTIONS FOR SAFE USING:

Ensure good ventilation during application and curing due to the release of acetic acid. Avoid contact with eyes and skin. Keep out of reach of children. Please consult the Safety Data Sheet (SDS) for detailed safety information.

STORAGE:

Store in the original unopened packaging in a dry place.

Temperature range: +5 °C to +25 °C.

Shelf life: 24 months from the date of manufacture.
