When some users choose silicone sealants, they focus on the curing speed. I think the faster the curing speed, the more time I save. Is this really the case? You might as well understand the curing speed, and don't affect the curing effect just to meet the deadline.
Is the curing speed really the faster the better?
In order to shorten the construction period, some users will purchase adhesives with fast curing speed. This approach is not correct. During the curing process, the reaction process between the crosslinking agent and the polymer is relatively complicated. If the time is too short, it will affect the strength and may become brittle. Blindly pursue the curing speed, there may be bubbles, so that the bubbles cannot be eliminated naturally, affecting the post-production effect. As a result, the construction period is shortened, but the quality cannot be guaranteed. It is recommended to let the adhesive cure naturally and not to pursue speed too much.
How long does it take to reach optimal strength?
The curing reaction of silicone sealants requires a long curing time, so a simple comparison cannot be made. Normally, after 24 hours, it can reach about 60% strength; after 72 hours, it can reach 75-80% strength; after 7 to 14 days, it can reach the best strength. It will take longer if a neutral adhesive is used. The curing time is different, and the strength achieved is different. Proceed to the next step according to specific requirements.
Is the silicone sealant easy to fall off?
Some users found that the normally poured silicone sealant fell off. It may have reacted with some materials and cause it to fall off. Choose a good quality and suitable adhesive to avoid falling off. Cooperate with powerful suppliers, such as TENSAN, which focuses on silicone sealant research and provides customized silicone sealant application solutions. It has a wide range of uses and can be used in new energy, military, medical, aviation, shipbuilding, and electronics. , automobiles, instruments, power supplies, high-speed rail and other industries.
In addition to the peeling phenomenon, once the surface is wrinkled, it means that there is too much plasticizer, or the glue layer is thin. Adjust the glue and pouring reasonably, so as not to affect the curing effect.
