2. Product Features
1. This product is a white paste, one-component, non-flowing, room temperature curing, neutral silicone sealant;
2. Using unique technology to effectively eliminate residual low boilers, it has the characteristics of environmental protection, low odor and non-corrosiveness to various materials;
3. Excellent adhesion properties, good adhesion to plastics such as glass, metal, ceramics, PC and PBT;
4. After contacting with the bulb of the led lamp, it will not turn yellow after being baked at high temperature in the drying tunnel;
5. It has excellent high and low temperature resistance, and maintains good strength and elasticity in the range of -30℃～230℃ after curing.
3. Main use
1. Bonding and sealing of lighting products, fixing of circuit board components, insulation and sealing of electrical switches;
2. Other places where caulking and sealing are required.

5. How to use
1. Ensure that the surface to be bonded is clean and dry, and remove all grease and contamination that may affect the bonding before gluing.
2. Apply a neutral sealant to the already pre-treated surface and quickly lay up the other side that needs to be bonded.
3. At room temperature, the sealant will tack dry within 20 minutes.
4. Store at room temperature in a ventilated place until the sealant is fully cured. Heating can also promote curing under sufficient moisture conditions.
Note: Regarding curing time. After the sealant is dry, curing will continue from the surface inwards. Under the conditions of room temperature and 50% relative humidity, the cured thickness of the sealant is not less than 2 mm within 24 hours. Parts with limited air contact will take longer to cure. Cure time is also extended in low humidity conditions. The specific curing time is determined by the user according to the specific use and application of the sealant.
6. Packaging and storage
1. Plastic cartridge.
2. The validity period is 6 months when stored in a cool, dry place below 35°C without unpacking.
3. The validity period is 6 months when stored in a cool, dry place below 27°C after unpacking.
Note: Since the sealant is easy to react with the moisture in the air and cure, the sealant container should be tightly sealed when not in use after opening. The sealant should be used up as soon as possible after opening. The unsealed sealant is prone to form a small amount of blocked closures at the end of the sealant tube during storage. These closures can be easily removed, and the remaining sealant can still be used.
Seven, matters needing attention
This product is non-toxic after it is completely cured, but it should avoid contact with eyes and skin before curing; pay attention to maintaining ventilation in the working environment area.
