Product Description

The HT S25 All-Purpose Silicone Sealant is a one-part, neutral cure, high modulus silicone designed for long-term weatherproofing and waterproofing.
Unlike acetoxy sealants, it is virtually non-corrosive, low-odor, and suitable for sensitive substrates.
It provides excellent adhesion to glass, metals, ceramics, wood, PVC, and aluminium composite panels, making it ideal for glazing, construction, and waterproof applications.
It can also function as an acoustical sealant to reduce sound transmission in wall systems.

Key Benefits

• Neutral Cure – Non-corrosive to metals and low odor.
• Excellent Waterproofing – Superior resistance to water and weathering.
• Elastic & Durable – Retains flexibility and prevents substrate stress under thermal changes.
• Acoustic Performance – Maintains STC ≥40 in wall systems (ASTM E90; C919).
• Movement Capability – ±25% dynamic joint movement (ASTM C719).
• Easy Application – Smooth caulking consistency and quick tack-free time (<30 min).

Applications

• Sealing joints in metal, glass, concrete, ceramic, wood, and PVC.
• Glass-to-glass and glass-to-metal sashing.
