Shelf life:
12 months in unopened packages in a cool and dry storage place at temperatures between +5 oC and 27 oC, humidity between 30% and 70%.

Direction for Use:
1. Before using this product, clean all metal, glass and plastic surfaces with solvents such as isopropanol and clean, oil-and lint-free cloths
2. To obtain ultimate physical properties, its Base and Curing agent should be thoroughly mixed using an airless mixing system.
3. The cure rate may be adjusted by changing the base-to-curing agent mix ratio from 16:1 to 14:1 by weight; sealant physical properties are not significantly changed over the range.
4. Care should take not to entrap air when mixing the two pastes. If this is unavoidable, the material must be subsequently evacuated.
5. The joints should be tooled immediately after sealant application to ensure complete substrate contact, which is a requirement for optimum adhesion.

Keep out of reach of children. Before the operation, please carefully read the specifications of products and materials and instructions on the
package of the container.
For more information about safety, please refer to the MSDS.

Industry knowledge

What is Two Component Polysulfide Sealant?
Two Component Polysulfide Sealant is a type of sealant used in construction, manufacturing, and other industrial applications. It is a two-part system consisting of a base compound and a curing agent that react together to form a durable, rubber-like material.
The base compound of a polysulfide sealant is typically a liquid polymer that contains long chains of sulfur atoms. When mixed with a curing agent, these chains cross-link to form a strong, flexible material that can withstand exposure to water, chemicals, and UV radiation.
Polysulfide sealants are commonly used for sealing joints and gaps in building materials such as concrete, masonry, metal, and wood. They are also used in the aerospace and automotive industries for sealing fuel tanks, engine compartments, and other critical components.
Polysulfide sealants have a number of advantages over other types of sealants, including excellent chemical resistance, high tensile strength, and superior adhesion to a wide variety of surfaces. They are also known for their long-term durability and resistance to weathering and aging.
Application of Two Component Polysulfide Sealant
Two Component Polysulfide Sealant has a wide range of applications across various industries. Some of the common applications include:
Construction: Two Component Polysulfide Sealant is used for sealing expansion and control joints in concrete and masonry structures, sealing gaps in roofing systems, sealing curtain walls, and other building envelope components.
Aerospace: Two Component Polysulfide Sealant is used for sealing fuel tanks, sealing aircraft windows, sealing access panels, and other critical components that require excellent resistance to fuels, oils, and other chemicals.
Automotive: Two Component Polysulfide Sealant is used for sealing seams and joints in automobile bodies, sealing automotive windshields, sealing body panels, and other automotive components.
Marine: Two Component Polysulfide Sealant is used for sealing below-waterline joints, sealing deck seams, sealing hatches, and other marine components.
Manufacturing: Two Component Polysulfide Sealant is used for bonding and sealing components in electronics, appliances, and other industrial products.
Two Component Polysulfide Sealant is particularly useful in applications where a high level of chemical resistance, flexibility, and durability is required. It can also withstand extreme temperatures and weather conditions, making it suitable for use in harsh environments.
Advantages of Two Component Polysulfide Sealant
Two-component polysulfide sealants are known for their excellent properties and many advantages, some of which include:
Durability: Two-component polysulfide sealants offer excellent durability and can resist weathering, aging, and most chemicals. They also have excellent flexibility, making them an ideal choice for sealing joints that are subjected to movement.
Low shrinkage: Two-component polysulfide sealants have very low shrinkage rates, which means that they can maintain a tight seal even after curing.
Adhesion: Two-component polysulfide sealants offer excellent adhesion to a wide variety of substrates, including concrete, glass, metals, and many plastics.
Wide temperature range: Two-component polysulfide sealants can withstand a wide temperature range, from -40°C to 90°C, making them suitable for use in a variety of environments.
Easy application: Two-component polysulfide sealants can be applied using standard caulking guns, making them easy to apply and suitable for both DIY and professional applications.
Versatility: Two-component polysulfide sealants can be used for a wide range of applications, including sealing joints in concrete, steel, and other materials, as well as for waterproofing and protecting against corrosion.
UV resistance: Two-component polysulfide sealants are also resistant to UV rays, making them suitable for outdoor applications.
Good chemical resistance: Two-component polysulfide sealants have excellent resistance to many chemicals, including gasoline, diesel fuel, and most acids and alkalis.
Overall, two-component polysulfide sealants are an excellent choice for many sealing and bonding applications, offering superior durability, flexibility, and adhesion.
