Product Description
MF890 Silicone Sealant
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 and weatherproofing applications♦ DESCRIPTION / APPLICATIONS

Glue injection method
Install appropriate gasket materials, adhesive spacers or tape as required.
Continuously squeeze the MF889A-25 silicone stone weathering sealant into and fill the joints. When the sealant surface is not yet skinned, press the sealant into the gasket material and the joint surface with appropriate strength. It is recommended to use convex tools to trim the rubber surface into a concave shape. Do not use soap or water as auxiliary materials for trimming.
After finishing the dressing, remove the masking tape immediately.
Be careful not to splash the uncured silicone sealant on non-abrasive surfaces, such as polished granite or other natural stones, because these wet silicone sealants cannot be completely removed with organic or chlorinated solvents. Therefore, these surfaces must be masked, or extra care must be taken when applying glue to prevent the sealant from contacting these surfaces, once the uncured sealant comes in contact with
These surfaces, it will leave a layer of film on the surface, which may affect the appearance of the substrate surface.

How to use instructions
Remove dirt, dust, oil, frost, etc. on the surface of the substrate; place the plastic nozzle on the open bottle mouth and tighten it, and use a dedicated 1:1 double bottle glue gun to inject glue. Uncured glue can be cleaned with special cleaning agents (or other solvents such as alcohol).

Precautions and precautions
The initial 20g of mixed glue may be insufficiently mixed and is not recommended.
The glue mixed at room temperature should be used during the application period.
Avoid contact with skin and eyes. If inadvertently, rinse immediately with plenty of water and consult a doctor if necessary;
avoid contact with children; do not contaminate food, medicine or cosmetics.
The heavy workpiece to be bonded should be avoided to move before it is completely cured, and measures should be taken to fix it when it is necessary to move.
Recommended use conditions: temperature 15 ~ 35C, relative humidity 40% ~ 80%; if the temperature and humidity are lower than the recommended lower limit, the horn glue will cure more slowly, and if it is higher than the recommended upper limit, the construction time will be shortened.
