Product Description

Introduction:

MF881-25 silicone structural sealant is a two-component, neutral cure, high flexibility, high modulus silicone sealant,to meet the technical requirements in GB16776 and ETAG002, which can provide quality assurance for 25 years.

Features:

High strength and high modulus.

Excellent adhesion properties.

Excellent resistance to high temperature.

No corrosion and no pollution to environment.

Purposes:

Mainly used for structural assembly of high building, super high rise curtain wall, large-size glass plate curtain wall, complex structural curtain wall, manufacture of Insulating Glass, can also be used on anti-corrosion sealing for pipeline flange, bridge, shipbuilding, sewage disposal factory, subway, construction, and oil platform.

Instructions:

1.Surface cleaning

To ensure the structural sealant with good adhesion, sticky surface must be clean, dry and free of dirt.

To prevent contamination of sealant surrounding joints,surface protection tape must be used to protect construction,when the construction is completed, the tape will be removed.

2. Cleaning Process

2.1 You must use a clean lint-free cloth

The solvent can be used to clean fresh ethanol, acetone, isopropanol, methyl ethyl ketone, xylene, etc.

2.2 Use "Method of double cloth"

a. Wipe the area with a piece of sticky infiltration by solvent clean lint-free cloth.

b. In the solvent evaporation before drying immediately with a second clean, lint-free cloth to wipe the surface.

c. Area must be cleaned after completion of construction within one hour, otherwise re-cleaning.

d. Use calico dip solvent rather than white cloth placed in the container infiltration,to avoid contamination container inside a clean solvent; used cloth should be replaced.

e. In the area, open flame is prohibited.

Mixing process:

Conduct mixing in a closed mixing system.

Com A and ComB are uniformly mix at 12: 1 weight ratio.

|Users can also be based on actual need to change the mixing ratio, and then adjust the curing speed. Distribution ratio (mass ratio) Com A: Com B = 11: 1 ~ 14: 1.

Precautions:

Engineering Materials must do compatibility and adhesion test before.

1. Use and refer to the technical information and safety data sheets.

2. Com B reactions can occur with water in the air, no long-term exposure to air.

3. If entering the eyes accidently, immediately wash with clean water.

4. Avoid prolonged contact with the skin, avoid contact with children.

5. Do not contaminate food, drugs or cosmetics.

Transportation:

MF881-25 is non-dangerous goods, can be transported by train, car, ship and airplane.

Safety Tips:

This product's Guide does not contain all the information Safety Notes, in order to secure the use of, should be read carefully before proceeding "structural silicone sealant construction norms" and product specifications, and contact your local sales company to obtain such information. Before use especially for bonding chrome surfaces (such as chrome coated glass), the former must be used to contact the company's technology department, after safety tests.

Where the product is not related to safety issues, follow JGJ102 requirements.

• The well-packaged product can be stored for 12 months in a cool, ventilated, and dry place, and used before the "expiry date" of the outer packaging of the product

  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.
