What Are the Unsuitable Occasions for Silicone Adhesive Sealant and How to Store It Properly?

Some industries require the use of silicone adhesive sealant to achieve desired results with multiple performance benefits. However, some silicone suppliers have reported that this adhesive does not work as expected and causes various issues. This is because it hasn't been used in the appropriate circumstances.

Silicone adhesive sealant has excellent high and low-temperature resistance

Formulated with high molecular components such as silicon, oxygen, and silicon bonds, it has improved heat resistance. Usually, regular adhesives will melt or age when exposed to high temperatures of 100 degrees, rendering them useless. However, silicone adhesive sealant is different and can still function normally even in a 150℃ environment. Its elasticity and strength are not significantly affected, making it suitable for long-term use. For a more reliable choice, collaborating with a reputable silicone product supplier such as ZHONGTIAN EAST, which specializes in silicone adhesive sealant research and offers customized solutions, is ideal. The multi-purpose silicone sealant can be used in various industries such as new energy, military, medical, aviation, shipping, electronics, automotive, instrumentation, power supply, and high-speed rail.

Circumstances when silicone adhesive sealant should not be used

Not every environment is suitable for using silicone adhesive caulk, such as places that are constantly exposed to water, frost or too humid, and surfaces that are not clean enough. It is also not easy to bond materials that contain oil stains, and they cannot be cured in a completely sealed state. This adhesive cures slowly with moisture in the air and cannot cure in a sealed environment.

Precautions to take when using silicone sealant caulk

Follow the correct procedure and do not reverse the steps. For instance, when using a two-component product, the adhesive must be mixed first before pouring. During the pouring process, adjust the amount of adhesive according to the gap size. Pour steadily and repeat the process if necessary. If the desired effect is not achieved, check the operation process, and choose a high-quality adhesive that doesn't affect the outcome.

Storage methods for silicone adhesive sealant

• Store multi-purpose silicone sealant in a cool and ventilated location between 4~28℃ to keep it dry.

• From the production date onwards, the shelf life is six months.

• Some adhesives have a shelf life of up to 12 months, and when stored correctly, they can still be used even after the expiry date. In order to save time and energy, do a small trial in advance to see how it performs. Only when it functions properly can it be used with peace of mind.
