Hi there, this is Tina Xie from Topsen Sealant. That's a really good question, and it's something we work on every day.
So, is more silicone always better? Well, it's not that simple. It's like building a good team.
Think of our sealant as a team of specialists. The silicone itself is the core team—it gives us the basics, like heat resistance and long-lasting flexibility.
But a team needs more than just stars. We add reinforcing fillers. They are the backbone that gives the sealant its strength, so it doesn't tear easily.
Then we have special additives. For example, in a bathroom sealant, we add anti-mold agents to fight moisture. These are the specialists that handle specific jobs.
So, our job in the lab isn't just to add more silicone. It's to figure out how to make all these different ingredients work together perfectly. That balance is what really creates a great product.
As a user, here's what to look for instead of just the silicone content:
Check the specs: Look for "movement capability" on the TDS. A higher percentage means it can handle stretching and squeezing better as things expand and contract.
Feel the quality: A good sealant shouldn't shrink much or have a strong smell after you apply it. That's a sign of a well-made, stable formula.
Pick the right type: Make sure you're using a sealant made for your specific job, like one labeled for kitchens and bathrooms if you need mold resistance.
To put it simply, at Topsen, we focus on how all the parts work together, not just one ingredient. We make sure every product is balanced and reliable for your project.
Hope that explanation helps. Let me know if you have any other questions.
