Wondering what kind of sealant will work for you? Both clear silicone (ซีลิโคนใส, which is the term in Thai) sealant and polyurethane sealant have different benefits and objectives. Let’s read the article below to consider your choice between polyurethane sealant and silicone sealant.
What Is Silicone Sealant
Silicone sealant is a gel like adhesive sealant that mostly acts like a gel. Compared to other sealants, the silicone sealant can maintain the elasticity in its best level even in changing temperatures.
What Is Polyurethane Sealant
The polyurethane sealant is another most flexible and versatile sealant that works on a number of applications such as wood, metal, plastic and etc. the polyurethane sealant generally works well on joints of prefabricated agents such as rainwater collection pipes.
The Difference Between Polyurethane Sealant And Silicone Sealant
There are main two differences between polyurethane sealant and Silicone sealant which are given below:
· Chemical Difference
The chemical composition is one of the most important benefits between silicone and polyurethane. While silicone sealants are an inorganic substance, the polyurethane is extremely organic. The organic compound or polyurethane contains carbon atoms that the silicone one doesn’t have. Sometimes, it also contains hydrogen atoms.
The polyurethane comprises a series set of organic atoms that are connected through carbamate, but the silicone comprises both organic and inorganic compounds. The silicone sealants works by attaching it’s organic compounds with the external forces. The inorganic one comes with the maximum ability to withstand UV rays. Polyurethane can get back to its natural state for excessive UV exposure.
· Lifespan
The silicone sealants work longer than the polyurethane one. The polyurethane sealants can go through its longer lifespan of 5 to 10 years. But the silicone joint don’t work within 20 years. Apart from that, it will remain in same condition even after facing too much UV exposure. The UV exposure akter the chemical compound, so temperature change may also affect the working of both of those sealant. If the joint sealant is subjected to change as per weather condition, then silicone joint will be the best solution due to its flexibility.
Silicone Sealant Is Best For Plumbing Application
The clear silicone sealant not only works best for everyday DIY and construction work, but also for homes with excessive moisture. The silicone sealant works best for the bathroom, kitchen and other high moisture areas.
Hopefully, you have understood which will be the best choice for your work. Let’s talk to your nearest manufacturer to know the best of their applications.
