FIXIT Hybrid Sealant – MS Polymer Technology (Würth)

Advanced Hybrid Sealant for Superior Flexibility & Durability

The FIXIT Hybrid Sealant combines the best properties of silicone and polyurethane in a high-performance MS polymer formula. Designed for construction, automotive, and industrial applications, it delivers exceptional elasticity, weather resistance, and adhesion—without the need for primers. Whether sealing joints, bonding panels, or protecting against vibrations, this sealant ensures long-lasting, professional-grade performance.

Key Features:

• MS Polymer Hybrid Formula – Strong adhesion without primers on most substrates (metal, plastic, wood, glass, and more).

• Exceptional Elasticity (450% elongation) – Accommodates movement and prevents cracking under stress.

• Wide Temperature Range – Performs in -40°C to +90°C after curing, ideal for extreme climates.

• Paintable Surface – Accepts coatings after 24-hour curing for seamless finishes.

• Quick Skin Formation (25 min) – Allows faster work progression compared to traditional sealants.

• 12-Month Shelf Life – Maintains performance when stored properly, reducing waste.

Technical Specifications:

• Content: 300 ml cartridge (standard caulking gun application)

• Hardness: 40 Shore A (±3) – Optimal balance of flexibility and strength

• Application Temp: 5°C to 50°C (optimal at 20°C)

• Density: 1.44 g/cm³

• Recovery: Excellent shape memory after deformation

Professional Applications:

• Construction: Sealing joints in facades, roofs, windows, and perimeter gaps

• Automotive: Bonding and sealing trim, panels, and accessories

• Industrial: Vibration-resistant sealing for machinery housings and equipment

• DIY & Home Projects: Weatherproof seals for doors, gutters, and outdoor fixtures

Usage Guidelines:

Best Practices:

✔ Surface Prep: Must be clean, dry, and grease-free for maximum adhesion.
✔ Application Temp: Apply between 5°C and 50°C for optimal performance.
✔ Tooling: Smooth joints immediately after application.
✔ Curing Time: Full cure achieved in 24 hours (varies with humidity/temperature).

Not Recommended For:

✖ Continuous immersion in water
✖ Chlorinated solvent environments
