- 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.
Features and Benefits
Two-component, curing at room temperature;.
Strong permeability, wide bonding range, high bonding strength to stone, concrete, metal and other materials;
There is still moderate flexibility after curing, and the crack will not crack again when it is impacted or vibrated inside the crack;
It does not contain volatile solvents, does not pollute the substrate, has good aging resistance, and will not shrink after curing;
It does not contain styrene and ethylenediamine and meets the non-toxic requirements.
Instructions for use
Surface cleaning:
a. The surface of the adhered material must be clean and free of dirt.
b. Derusting layer on metal surface.
Mixed process:
a. Mix the two components A and B evenly at a mass ratio of 2:1.
b. Construction time: about 10 minutes (23+2C).
Precautions
1. The surface to be adhered should be clean, dust-free, dirt-free, and not loose.
2. The amount of glue should be appropriate each time, and the cover should be sealed immediately after use to avoid waste. The tools used for the A and B components cannot be used in common and should be placed separately.
3. Please do a cohesive test before use and refer to the company's technical data and safety data sheet.
4. Can not be mixed with other sealants.
Package
Component A: 1kg/bottle 10kg/drum
Component B: 0.5kg/bottle 5kg/drum
Storage
This product should be stored in a cool, dry and ventilated place. The storage period is 12 months.
