Product Description

MF890 Silicone Sealant

RTV, Neutral, One-Part Silicone Sealant
 

DESCRIPTION / APPLICATIONS
SILANDE MF890 Silicone Sealant is a one- part, RTV neutral-cure, architectural grade sealant. It easily extrudes in any weather and cures at ambient temperature by reaction with moisture in the air to form a durable, flexible silicone rubber seal. SILANDE MF890 may also be used to seal for housing window and door, freight container, car glass, metal cladding, ducting and interior sealing in building and housing, also designed for use in sealing for general glazing and showroom glazing ans weatherproofing applications.
 

 LIMITATIONS

SILANDE MF890 is not suitable for structural glazing use.

SILANDE MF890 should not be applied to: DO NOT USE when application surface temperatures below 4°C or exceed 50°C,. Surface which will be painted, as painting over rubber is not recommended.

Do not use water for tooling and do not apply to wet or damp surface.
On surfaces that are continuously immersed in water.

 PREPARATION INSTRUCTION

• For good adhesion, a clean, dry and grease free surface is necessary. All contaminants, impurities, or other adhesion inhibitor (such as moisture/frost, oils, old sealant, soaps and other surface treatment, etc.) must be removed from the surfaces to which the sealant is intended to adhere.
• For cleaning, a solvent-dampened clean rag usually produces the desired result. Isopropyl Alcohol (IPA) is s commonly used solvent and had proven useful for most substrates.
• The use of masking tape is recommended where appropriate to ensure a neat job and to protect adjoining surfaces from over-application of sealant Masking tape should be removed immediately after tooling the sealant and before the sealant begins to skin over (tooling time).
• Extrude with manual and pneumatic sealant gun, cut tip to desired bead size, puncture seal in nozzle and remove metal seal on end of cartridge before placing cartridge in caulking gun. Make bond before the product skins. Adhesive sealant must be used within 30 mins after inner seal is punctured. Good ventilation is necessary in the process of installation and curing. To ensure the best adhesive properties, do a test on adhesion before using in batches and peeling adhesion tests at regular intervals are also required while carrying out installation.

APPLICATION METHODS
SILANDE MF890 may not adhere or maintain long term adhesion to substrates if the surface is not prepared and cleaned properly before sealant application. Using proper materials and following prescribed surface preparation and cleaning procedures is vital for sealant adhesion. SILANDE MF890 is easily dispensed directly from cartridges and foil sausage using standard caulking guns or air operated guns. Mixing, heating and refrigeration are not required.
