Sikaflex 127 Multipurpose Hybrid PU Sealant and Adhesive (600 ml)
Sikaflex-127 — Single-Component Hybrid Polyurethane Sealant and Adhesive for Interior and Exterior Joints
Sikaflex-127 is a single-component, elastic, moisture-curing hybrid polyurethane sealant and adhesive from Sika India. Based on a silane-terminated polymer, it bonds to a wide range of construction materials without special pre-treatment on most substrates and delivers good weathering and ageing resistance for both interior and exterior sealing applications. Its dual function — as a joint sealant and a structural adhesive — makes it a practical choice for contractors who need one product to seal connection joints, bond construction components, and handle facade sealing. Isocyanate and solvent free, overpaintable, and available in concrete grey, white, and black. Packaged in 600 ml foil packs and 300 ml cartridges.
Key Features
- Dual Function — Sealant and Adhesive: Seals construction joints and bonds materials including concrete, masonry, ceramic, wood, metals, glass, plastic, PVC, and aluminium composite panels
- Bonds Without Special Pre-Treatment: Adheres to a wide variety of substrates without primers or activators on most surfaces — reducing preparation time on site
- Isocyanate and Solvent Free: Low odour, safer for applicators, environmentally responsible formulation
- Overpaintable: Compatible with most conventional facade coating paint systems after full cure
- Good Weathering and Ageing Resistance: Maintains elasticity and adhesion through UV exposure, temperature cycling, and rainfall
- Fast Skinning: Skin time approximately 40 minutes at +23°C — faster workflow compared to standard PU sealants
- Non-Sag: Suitable for vertical and overhead joints without slumping
- Chemical Resistance: Resistant to fresh water, seawater, diluted acids, and diluted caustic solutions
Applications
- Connection joints, window frames, and door perimeters
- Facade sealing and precast concrete element joints
- Bonding gutters, drip trays, flashings, and connection joints
- Bonding construction components — concrete, masonry, stones, ceramics, wood, metals, glass, plastic, PVC, and aluminium composite panels
- Interior and exterior sealing applications requiring overpaintable finish
- Applications requiring sealing and adhesion in a single product
