RT-6500 is a single-component, neutral-curing silicone sealant engineered for a wide range of construction and glazing applications. It cures at room temperature through exposure to air moisture, forming a flexible and durable seal that resists weather, aging, and thermal stress.
Key Advantages
1.Neutral Cure System - Safe for metal, stone, and other sensitive materials
2.Strong Adhesion - Bonds well to glass, aluminum, ceramic, concrete, and more
3.Weather & UV Resistant - Performs reliably in outdoor conditions
4.Permanently Flexible - Absorbs movement without cracking or shrinking
5.Easy to Use - Ready-to-apply formula, no mixing required
Recommended Uses
1.Window and door sealing
2.Glass façade and curtain wall joints
3.Showcases and glass panel installation
4.Sealing around marble, stone, and metal fixtures
5.Indoor and outdoor gap filling and joint sealing
