Product Description

Product Description

Two-Component Polysulfide Sealant Is Perfect for Construction Caulking

Two-component polysulfide sealant, as known as a two-component, non-sag, premium polysulfide sealant, which is also called polysulfide sealant for building made up of liquid polysulfide rubber, and add tackifying resin, vulcanizing agent, accelerant and fortifier into it. It contains two components and it can vulcanize and crosslink by itself at room temperature. The two components have clear color difference, which makes the mixing more convenient. It can keep good air tightness and water resistance in continuous vibration and temperature changes. In addition, it has a good bonding effect for metal, concrete and other materials.

The two-component polysulfide sealant is a high-performance elastic sealing material, categorized as a reactive adhesive. It consists of a base compound (Component A) and a curing agent (Component B). When mixed in a specific ratio prior to use, it chemically reacts and cross-links with various substrates (e.g., concrete, steel, glass) to form a flexible, durable elastomer. Renowned for its exceptional chemical stability, aging resistance, and excellent elastic recovery, this product is specifically engineered for long-term engineering seals that must withstand dynamic movement and harsh environments.

Features
*Exceptional Durability: Possesses excellent weather resistance, aging resistance, and UV resistance, ensuring a long service life with slow performance degradation.
*Outstanding Media Resistance: Maintains good stability and resistance to water, oils, fuels, and various chemical solvents.
*Broad Temperature Adaptability: Maintains elasticity across a wide range, with excellent low-temperature flexibility (down to -30°C to -40°C) and no flowing at high temperatures.
*High Elasticity & Recovery: High elongation at break (typically ≥100%, some types up to 400% or more), capable of accommodating large-amplitude, frequent reciprocating movement.
*Environmental & Safety: Often solvent-free or low-solvent formulations; inert solid after curing, environmentally friendly.

Function
*Dynamic Sealing: The cured, highly elastic rubber body effectively follows and seals dynamic expansion, contraction, deformation, and displacement of joints, preventing leakage.
*Strong Adhesion: Provides excellent chemical and physical bond strength to substrates like concrete, metals (steel, aluminum), glass, and some plastics, ensuring a secure, non-detaching seal.
*Multi-Protection: Offers reliable waterproofing, moisture resistance, air tightness, and sound insulation, while protecting substrates from water and corrosive media.
*Stress Buffering: The flexible sealant absorbs and disperses stresses induced by temperature changes, loads, and vibrations, protecting the structures on both sides of the joint.

Application

The polysulfide sealant is suitable for outdoor or indoor and can be used to seal both static and dynamic joints:

    *Used to caulk at concrete, building, and bridge.
    *Used in anti-leakage caulking of various types of expansion joints, such as waterworks, swimming pools, reservoirs, power plants, dams, sewage treatment works and water supply and drainage systems and other projects.
    *Used as the joints of precast concrete, and the seams of the glass and construction.
    *Used in the seaming of metal siding, and the bonding of aluminum window frame.

In modern buildings, more and more designers use polysulfide sealant to seam metal siding and bond aluminum window frame.

The polysulfide sealant is used to waterproof at water related projects, such as swimming pool.
