Description

LOTFIX C12 Weatherproof Silicone Sealant is a one-component neutral cure silicone sealant developed for exterior sealing where long-term weather exposure is a key consideration. It is suitable for curtain wall joints, glass, aluminum, steel, brick, concrete, and other common building materials that require durable outdoor sealing.

This product is designed to resist outdoor weathering, vibration, temperature extremes, and UV exposure while maintaining a strong weatherproof seal. Its main value is stable performance in exterior construction areas where changing weather and joint movement must be considered together.

Why This Product Stands Out

- Built around outdoor weatherproofing rather than only indoor sealing.

- Excellent UV resistance for exterior exposure.

- Suitable for construction joints where movement can occur.

- Resistant to temperature extremes, aging, and cracking.

- Suitable for curtain walls, facades, and external aluminum composite panels.
