12 Pack of SikaFlex 112 Crystal Clear Sika – Multipurpose Transparent Adhesive and Sealant – 290 cm³

1. Main Characteristics

• Complete Transparency: As the name suggests, Sikaflex 112 Crystal Clear is transparent once dry, making it an excellent choice for applications where appearance matters and the adhesive should not be visible.
• Versatile: This product combines the properties of a sealant and an adhesive, so it can be used for both bonding materials and sealing joints.
• High Adhesion: It has very good adhesion on many materials, including wood, concrete, glass, metal, PVC, and certain plastics, without requiring a primer.
• Flexible: After drying, it retains some elasticity, allowing it to adapt to material movements and vibrations.
• Solvent-Free and Odorless: Formulated to be solvent-free, making it safer to use indoors.
• Weather Resistant: Suitable for outdoor applications, as it resists UV and temperature variations.

2. Common Uses

Sikaflex 112 Crystal Clear is highly valued for its versatility and ease of use in various types of work:

• Fixing and Bonding: Ideal for bonding shelves, supports, panels, and various accessories in homes or offices. It can be used on both non-porous and porous surfaces.
• Joint Sealing: Often used for finishing joints around windows, doors, baseboards, and even in bathrooms and kitchens.
• Various Repairs: Suitable for small repairs, such as fixing decorative objects or sealing joints.

3. Application

To apply Sikaflex 112 Crystal Clear:

• Surface Preparation: Ensure surfaces are clean, dry, and free of dust, oil, or other contaminants.
• Application: Using a cartridge gun, apply the product to one of the surfaces to be bonded or in the joint to be sealed.
• Drying Time: Drying time depends on environmental conditions but reaches full cure in about 24 hours.
• Cleaning: Before drying, Sikaflex 112 can be cleaned with specific products or solvent-soaked cloths.

4. Advantages and Limitations

• Advantages: High versatility, transparency, weather resistance, good adhesion on many materials.
• Limitations: Not suitable for underwater applications; certain specific plastics may require compatibility testing, and polyethylene or polypropylene surfaces may not adhere.

5. Precautions

As with any sealing and bonding product, it is recommended to work in a well-ventilated area and avoid prolonged skin contact.
