MF212 Silicone Weather Sealant
Introduction:
MF212 is a single component, neutral cure, high flexibility, high modulus silicone sealant that offers excellent oil resistance, electrical insulation, water resistance, and resistance to high and low temperatures.
One-component, neutral, room temperature moisture curing silicone sealant. 1. Excellent flame-retardant performance, long time for fire blocking. 2. High elasticity and low modulus. It can be used with silicone fire-proof smoldering structural sealant that meets ETAG002 standard to provide 25-year quality guarantee. 3. Excellent resistance High and low temperature performance and weathering resistance performance 4. Neutral curing, no corrosion to the surface to be adhered 5. Good adhesion to most building materials and components without primer 6. It is stretching, connecting, and surrounding Ideal sealing material for sealing and fire blocking 7. Easy to use, it can be extruded at any time with a general glue gun. 8. Ring alignment

♦ TECHNICAL DATA - TYPICAL PROPERTIES
MF322 two-component polyurethane corner glue
Mainly used for bonding and sealing between aluminum alloy corners and profile cavities in aluminum alloy door and window structures; suitable for bonding wooden doors, windows and doors; for processed different materials, such as wood, building materials, ceramics and metals It has good adhesion.
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).

Store
Can be stored for 6 months in a cool, ventilated and dry place.
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.
Features:
- High flexibility and high modulus for neutral curing without corrosion on all surfaces.
- Excellent resistance to high temperatures and oils.
- Good electrical insulation properties in environmentally polluted conditions.
Purposes:
- Used for sealing combined face and flange surfaces in engine blocks of cars, motorcycles, etc., as well as oil pans and transmissions.
- Applicable to joint surfaces in hydraulic machinery equipment such as pumps, fuel pumps, hydraulic pumps, air compressors, etc., where sealing is required.
- Can replace various restrictions, such as rubber pads, on the edge of *** mats and other vehicles, motorcycles, and machinery and equipment engines, gearboxes, etc., for joint surface sealing, regardless of size and shape.
Instructions:
- Can be directly extruded at temperatures ranging from 10 ºC to 50 ºC.
- Ensure good adhesion by wiping off moisture, grease, dirt, etc., from bonding surfaces, ensuring they are clean, dry, and free of dirt.
- Use surface protection tape to protect surrounding construction joints from sealant contamination. Remove the tape after dispensing.
- If there is remaining glue after use, release air from the tube and tighten the lid for future use.
Restrictions:
- This product is not suitable for the following situations:
- Leaking grease, plasticizers, or solvents.
- Surface or semi-vulcanized rubber vulcanization.
- Frost or damp surfaces.
- Bonding copper and copper alloy surfaces in closed states.
Precautions:
- In case of eye contact, immediately wash with water.
- Avoid prolonged contact with the skin and keep away from children.
