Product Overview
Everbuild Everflex 225 Industrial & Glazing Silicone supplied in a 295ml cartridge is a mid-modulus, acetoxy-cure silicone sealant formulated for glazing and general industrial applications. It forms a durable, high-strength waterproof seal on smooth, non-porous materials such as glass, aluminium, steel, and uPVC.
Designed for both sealing and bonding, it provides excellent flexibility after curing and withstands temperature variations up to +200°C, making it suitable for interior and exterior use. Its fast skinning and curing characteristics allow for efficient application in both workshop and on-site environments.
The black colour provides a smooth, uniform finish suited to dark-framed glazing, metalwork, and industrial assemblies.
Features & Benefits
- Mid-Modulus Acetoxy-Cure Formulation: Delivers strong, flexible bonding and sealing performance on smooth, non-porous surfaces.
- Fast Curing and Easy Tooling: Skins within minutes to allow rapid finishing with minimal dirt pickup during cure.
- Temperature Resistant to +200°C: Suitable for industrial and glazing applications exposed to elevated or fluctuating temperatures.
- Waterproof and Weather Durable: Provides a watertight seal for long-term protection in both internal and external environments.
- Excellent Adhesion: Bonds effectively to glass, aluminium, steel, uPVC, and many coated or polished materials.
- Black Colour Finish: Produces a clean, uniform joint line ideal for use with dark window frames, curtain walling, and industrial components.
Applications
- Glazing Seals: Suitable for single-glazing, butt glazing, and channel glazing of glass and metal.
- Metal and Aluminium Sealing: Bonds and seals glass-to-metal and metal-to-metal joints.
- uPVC Trims and Panels: Acts as an adhesive and sealant for fitting trims, cladding, and perimeter joints.
- Industrial Assembly: Used for gasket sealing, machinery assembly, and general maintenance sealing.
- Worktop and Panel Joints: Ideal for sealing between laminated panels and work surfaces.
- Gutter and Roof Details: Suitable for sealing aluminium gutters and similar joints.
Installation Guidance
- Surface Preparation: Ensure all substrates are clean, dry, and free from dust, oil, or old sealant residues.
- Priming: Porous surfaces may require priming; test a small area prior to full application.
- Application Method: Apply using a standard cartridge gun, cutting the nozzle at a 45° angle slightly larger than the joint width.
- Joint Design: Maintain correct depth-to-width ratios, avoiding three-sided adhesion for maximum flexibility.
- Finishing: Smooth the sealant within 10 minutes using a spatula or wetted tool for a neat joint appearance.
- Cleaning: Remove uncured material with white spirit; use Everflex Silicone Eater for cured sealant removal.
