◎ Characteristics and advantages

One- component, neutral curing, high strength, high adhesion,high modulus, and strong resistance to displacement.

Compared to most building materials, excellent bonding and sealing performance can be achieved without the need for primer, and it has good extensibility, water tightness, and other functions.After solidification, the product forms a cold resistant, heat resistant, and corrosion-free elastomer with excellent weatherproof,Anti aging, UV resistance, ozone resistance, high and low temperature resistance, no pollution to the environment.

Product advantages

One  component, neutral, room  temperature  moisture  curing  weatherproof  silicone sealant.

Application

For glass curtain wall, stone curtain wall (marble, granite) and metal structural engineering weatherproof sealing.

Suitable for edge sealing, joint sealing, and other types of building and industrial sealing.

Colour

Black, grey, and white, special colors can also be negotiated and formulated according to customer requirements.

Usage method

Surface cleaning

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

Use primer

Generally,no requirement primer. If the adhesion test indicates primer requirement, apply the primer thinly to the interface surface with a clean, lint free cloth and let it dry before injection. Before injecting sealant, it’s necessary to conduct corresponding tests to determine whether primer needs to be applied.

Lining material

Open cell polyurethane foam, closed cell polyethylene foam or non deflating polyolefin material are recommended as cushion materials. For shallow joints that cannot accommodate foam rods, polyethylene tape can be used instead.

Shelter and correction

The area near the joint needs to be covered to ensure a perfect and neat appearance of the sealing area. Do not allow the masking tape to come into contact with the surface of the substrate that is about to be glued. After the finishing work is completed, the masking tape should be immediately removed.

Sealant injection

Continuously squeeze and fill the interface with OM900 one-component curtain wall weatherproof sealant. Press the sealant onto the gasket material and interface surface with appropriate force, and the finishing process must be completed in one go after the injection of the sealant is completed and before the adhesive surface has peeled. It is recommended to use convex or suitable tools to smooth the adhesive surface, and soap and water cannot be used as auxiliary materials for trimming. After finishing, immediately remove the covering tape. On the glass assembly, the sealant injected at the bottom interface needs to be trimmed into an inclined surface to prevent water accumulation. In outdoor temperatures as low as -25 ℃, the ○M900 one-component weatherproof sealant for curtain walls can still be extruded and applied to a clean, dry, and frost free surface.

Uncured sealant is absolutely not allowed to come into contact with non grindable 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 should be taken when injecting sealant to prevent contact between the sealant and these surfaces. Once the uncured sealant comes into contact with these surfaces, it will leave a thin film on the surface, which will affect the unique aesthetics of the substrate. If the uncured sealant comes into contact with the adjacent surface of the interface, it is necessary to use toluene, xylene, or methyl ethyl ketone solvents to remove it before the sealant has cured. When using flammable solvents, special precautions should be followed.

Precautions for operation

It cannot be used for structural bonding assembly.

It should not be used on the surface of all objects that have oozed grease, plasticizers, or solvents.

It should not be used in enclosed spaces or on surfaces that come into direct contact with food and drinking water.

Keep the substrate surface clean and dust-free, and the temperature of the construction site should not be lower than 10 ℃. It’s not suitable to bond substances containing copper or copper alloys.
