.APPLICATION FIELD

• One component, solvent free, non-fogging, permanently plastic butyl sealant, formulated for primary sealing of insulating glass units.
• It can keep its plastic and sealing properties in a wide temperature range.
• Excellent adhesion properties on glass, aluminum alloy, galvanized steel and stainless steel.
• Minimum moisture vapour and gas permeation.
• Excellent temperature stability: - 30°C to 80°C.

♦ 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).

Packaging

Packaging
1:1 double plastic bottle packaging: 600 ml per group; 9 groups per carton

Transport transmission
This product is non-hazardous and can be transported by train, car, ship and plane

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.

PREPARATION  INSTRUCTION

For good adhesion, a clean, dry and rease free surface is necessary. All contaminants, impurities r 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 t adhere. Clean by using a two-rag wipe technique - wet one rag with s lvent and wipe the surface with it, then use the second rag to wipe the wet solvent from the Surace before it evaporates. In all cases where used, solvent should be wiped dry with a clean , white cloth or other lint-free wiping materials.
For cleaning, a solvent-dampened clean rag usually produces the desired result. lsopropyl Alcohol (IPA) is comm nly used solvent and has proven useful for most substrates.
Cleaning of surface sh uld be done within 1 t 2 hours of when the sealant is to be applied.
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 pro uct 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
Install backing  materials  joint
fillers,   setting   blocks,  spacer
shims and tapes. Mask areas adjacent to joints to ensure neat sealant lines. Primer is generally not required on non-porous surfaces, but maybe necessary for optimal sealant of certain porous surfaces. A test placement is always recommended. Apply MF889 Silicone Weatherproofing Sealant in a continuous operation using a positive pressure. (The sealant can be applied using many
types  of  air-operated  guns  and
most types of bulk dispensing equipment. Betore a skin forms (typically within 15 minutes), tool the sealant with light pressure to spread the sealant against backing matrial and the joint surfaces.  Remove masking  tape
as soon as the bead is tooled
