【Characteristics and Advantages】

One-component, neutral curing, high strength, high adhesion, high modulus, and strong anti-displacement ability.

It can achieve excellent bonding and sealing performance with most building materials without a primer, and has good ductility, water tightness and other functions.

After curing, the product forms an elastomer that is cold and heat resistant and non-corrosive. It has excellent weather resistance, anti-aging, UV resistance, ozone resistance and resistance to high and low temperatures, and causes no pollution to the environment.

【Composition】

One-component, neutral, room-temperature water vapor curing weather-resistant sealant.

【Application】

1、Sealing for glass curtain walls, aluminum single panels, stone curtain walls (marble, granite) and metal structure projects.

2. Sealing of joints in Bridges, door and window frames, as well as waterproofing and sealing of roof joints and concrete structures

3. It is applicable to edge banding, joint sealing and other types of building and industrial sealing.

【Color】

In addition to black, gray and white, special colors as required by customers can also be negotiated for production

【Application method】

【Surface cleaning】:

Remove all impurities and contaminants such as grease, dust, water stains, frost, surface dirt, old sealant, assembly accessories and protective coatings remaining at the joints and assembly parts.

【Primer】:

Generally, no primer is required when using OM900 one-component weather-resistant sealant for curtain walls. If the adhesion test indicates that a primer is required, apply a thin layer of the primer to the interface surface with a clean, non-lint cloth before injecting the adhesive and let it dry. Before injecting the glue, corresponding tests must be conducted to determine whether a primer is needed.

Gasket material

Open-cell polyurethane foam, closed-cell polyethylene foam or non-venting polyolefin materials are recommended padding materials. As for shallower joints that cannot accommodate foam rods, polyethylene tape can be used as a substitute.

【Masking and correction】

The areas near the seams need to be covered to ensure that the appearance of the sealed parts is perfect and neat. Under no circumstances should the masking tape come into contact with the surface of the substrate that is about to be coated with adhesive. After the finishing work is completed, the masking tape should be removed immediately.

【Injection of glue】

Continuously squeeze in and fill the interface with 0M900 one-component weather-resistant sealant for curtain walls. Press the sealant flat onto the gasket material and the interface surface with appropriate force. The finishing process must be carried out in one go after the injection of the sealant is completed and before the sealant surface forms a skin. It is recommended to use convex shapes or suitable tools to smooth out the rubber surface. Do not use fertilizer or water as auxiliary materials during the smoothing process. After the repair is completed, immediately remove the covering tape. On the glass assembly, the sealant injected at the bottom interface needs to be trimmed into a bevel to prevent water accumulation. Even when the outdoor temperature drops to -25℃, the OM900 one-component weather-resistant sealant for curtain walls can still be extruded and applied to clean, dry and frost-free surfaces. Uncured sealant must never come into contact with non-abrasive surfaces, such as polished marble, metal or glass surfaces, as excess sealant cannot be completely removed with organic or chlorinated solvents. Therefore, these surfaces must be covered or extra care must be taken when injecting the sealant to prevent it from coming into contact with them. Once the uncured sealant comes into contact with these surfaces, it will leave a film on them, thus affecting the unique aesthetic appearance of the substrate. If the uncured sealant comes into contact with the adjacent surface of the interface, it must be removed with toluene, xylene or methyl ethyl ketone solvents before the sealant has cured. When flammable solvents are used, specific precautions should be followed.

【Precautions for Operation】

◆ It cannot be used for structural bonding assembly.

◆Do not apply directly to the surfaces of all objects that exude grease, plasticizers or solvents.

◆not use directly in confined Spaces or on surfaces that come into direct contact with food and drinking water.

◆The surface of the substrate should be clean, dry and dust-free. The temperature of the construction site should not be lower than 10℃, and it is not advisable to bond substances containing copper or copper alloys.
