MF962 Silicone Sealant Electronic
Introduction:
MF962 is two component, neutral cured at room temperature, high elasticity silicone sealant. It has excellent flame retardancy, excellent resistance to UV and air aging. Mainly applied in the encapsulation and sealing of solar cell module, photoelectric display, and other electronic products, etc.
Characteristics:
High elasticity. Excellent flame retardancy. No pollution to the environment.
Neutral cure, non-corrosive to the surface. Outstanding resistance to UV and air aging.
Can be extruded directly at 10ºC~50ºC; excellent adhesion to glass, ceramic, metal materials.
Excellent resistance to low an high temperature, keeping good ability even in the range of -60ºC~200ºC.
Purposes:
Solar cell module encapsulation and sealing.
Photoelectric display encapsulation and sealing.
Various electronic products encapsulation and sealing.
Typical Product Data:
Glue injection
As shown in Figure 1, install the cushion material, spacer spacer and masking tape. Continuously squeeze DJ-A3-MF899F into and fill the joints. Flatten the sealant on the gasket material and the surface of the joint with an appropriate force. The finishing process must be done at one go after the injection is completed and the surface is not skinned.It is recommended to use convex tools to trim the rubber surface into a concave shape, and soapy water should not be used as an auxiliary material for trimming. After the trimming is completed, immediately tear off the masking tape. On the glass assembly, the sealant injected on the bottom seam must be trimmed to a bevel to prevent water accumulation. Uncured sealant is never allowed to come in contact with non-grindable surfaces, such as polished marble, metal or glass surfaces, because excess sealant cannot be completely removed with organic or chlorinated solvents. Therefore, these surfaces must be covered, or extra care must be taken when injecting glue to prevent the sealant from contacting these surfaces. Once the uncured sealant touches these surfaces, it will leave a film on the surface, which will affect the unique aesthetics of the substrate.

♦ 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

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.
Standard: GB/T 528 GB/T 531 GB/T 1692 GB/T 1695 UL 94
Methods of Application:
1. For good adhesion, the surface must be clean and dry without dust. Special materials (such as copper, polycarbonate, polypropylene, polytetrafluoroethylene, etc.) need compatibility test before using to determine the preprocessing method for good adhesive property.
2. In case of limited access to air or low humidity, curing time will be extended.
3. Masking tape should be used for preventing contamination and be got rid of after sealing.
Mixture:
MF962 should be mixed in sealed mixing and sealing machine, at the weight ratio of 12:1 (Com A: Com B). The ratio can be changed between 11:1 to 14:1 to adjust the curing time.
