Sika Polysulphide Two-Part Sealant for Expansion Joints (Gun and Pour Grade) {4 kg}
Sika Polysulphide Pour Grade — Two-Component Polysulphide Sealant for Horizontal Expansion Joints
Sika Polysulphide Pour Grade is a two-component, cross-linking polysulphide sealant from Sika India. Permanently flexible, self-levelling, and chemically resistant, it is designed for horizontal expansion joints where large movement is anticipated — in concrete construction, civil engineering structures, and joints between diverse construction materials subject to vehicular traffic. It forms a watertight, flame and fuel-resistant seal across a joint width range of 5 to 50 mm and passes the Flame Resistance Test to BS 5212-1990. Compliant with BS 4254-1983, BS 5212-1990, IRC:57-2006, IS:12118 (Part 1), and JIS K 6820 — a multi-standard product specified for infrastructure projects. Available in grey paste in 4 kg packs.
Key Features
- Self-Levelling Pour Grade: Flows into horizontal joints without tooling — achieves full contact and a flush finish on trafficked surfaces
- Permanently Elastic and Watertight: Forms a durable watertight seal that remains flexible through years of traffic and thermal movement
- Flame and Fuel Resistant: Passes BS 5212-1990 Flame Resistance Test — suitable for airport aprons, fuel stations, and road joints
- High Chemical Resistance: Chemically resistant to water, fuels, oils, and solvents — performs in infrastructure environments with chemical exposure
- High Elastic Recovery: >75% elastic recovery before ageing, after heat ageing, and after fuel immersion — sustains performance over the full service life
- Broad Standard Compliance: BS 4254-1983 / BS 5212-1990 / IRC:57-2006 / IS:12118 / JIS K 6820 — meets multiple infrastructure and Indian road specifications
- Long Pot Life: >90 minutes at 30°C — adequate working time for large pours on site
- UV and Weathering Resistant: Maintains performance and seal integrity in exposed outdoor joints
Applications
- Horizontal expansion joints in precast concrete elements
- Dams, reservoirs, and water treatment plants
- Residential and commercial building floor joints
- Subways, bridges, culverts, and tunnels
- Rigid pavements of highways, airport runways, and aprons
- Joints subject to vehicular traffic loading
- Joints between diverse construction materials with large anticipated movement
