Two Component Polysulphide Sealant for Expansion Joint

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Expansion Joint Sealing: Designed to fill and seal expansion joints in buildings, providing durable waterproofing and flexibility to accommodate structural movement.
  • Multi-Surface Adhesion: Formulated with rubber-based material for strong bonding on walls, pools, and building coatings, ensuring long-term resistance to water, UV, and chemicals.

Key features

  • 1. Corrosion-Resistant Polysulphide Rubber Formulation

    • With corrosion-resistant polysulphide rubber formulation, ensure long-lasting durability in harsh environments such as pools and chemical exposure. Outperforms silicone sealants in chemical resistance*

  • 2. Pre-Measured Dual-Component Packaging

    • With pre-measured dual-component packaging, simplify application by eliminating the need for manual mixing ratios, reducing errors compared to single-component systems*

  • 3. High Movement Capability for Dynamic Structures

    • With a 25% greater movement capability (±25% joint movement) than standard sealants, accommodate expansion and contraction in dynamic building structures like bridges or high-rise apartments*

  • 4. Multi-Environment Versatility

    • Designed for multi-environment use, effectively seal joints in pools (chemical resistance), hospitals (hygiene standards), and commercial buildings (high traffic), offering a one-sealant solution for diverse applications*

  • 5. ISO 9001:2008 Certified Quality Assurance

    • Backed by ISO 9001:2008 quality certification, guarantee consistent performance and safety compliance, meeting international standards for construction materials. Specifications subject to manufacturer confirmation.

Product details

Two Component Polysulphide Sealant for Expansion Joint

The Two Component Polysulphide Sealant is engineered for durable, weather-resistant sealing in expansion joints and structural gaps across diverse environments. Its rubber-based formulation ensures flexibility, adhesion, and longevity, making it ideal for construction projects like buildings, pools, and infrastructure.

Technical specifications

FeatureSpecificationBenefit
MaterialPolysulphide rubber compoundHigh elasticity and chemical resistance
ApplicationExpansion joints, walls, roofs, poolsVersatile for indoor/outdoor sealing needs
Durability20+ years service life (per ASTM D3818)Long-term protection against environmental stress
Adhesion Strength≥1.2 MPa (on concrete)Bonds securely to most substrates without priming
Curing Time24-48 hours (adjustable via mixing ratio)Flexible installation scheduling

Customization guide

Adjustable mixing ratios (Component A:B = 10:1 to 15:1) allow customization of curing speed and final hardness to meet project-specific needs. For high-traffic areas, increase Component B for faster curing; for deep joints, reduce B for extended work time.

Supplier's note

  1. Technical Breakthroughs:

    • Rubber-like cured structure: Enables 500% elongation in the Pro model, outperforming traditional silicone sealants by 40%.
    • ISO 9001:2015 certification: Ensures consistent quality across all models, critical for large-scale construction projects.
    • Adjustable curing chemistry: Base/Advanced/Pro models offer tailored cure times, reducing downtime by up to 50% in Pro setups.

  2. Version Selection Guide:

    • Base Model: Ideal for standard residential sealing (e.g., apartment window joints) where moderate flexibility and cost-efficiency are priorities.
    • Advanced Model: Suited for commercial buildings (e.g., hotel expansion joints) requiring enhanced adhesion and UV resistance.
    • Pro Model: Best for industrial environments (e.g., chemical plants, pool decks) demanding extreme durability and resistance to corrosive agents. With its tripled chemical resistance, the Pro version safely seals joints exposed to harsh solvents, while its rapid cure time accelerates project timelines.
