Final answer:
The Sikalastic 720/745 system offers enhanced durability, better mechanical properties such as higher tensile strength, a wider service temperature range, and excellent chemical resistance compared to the Sikalastic 390/395 system, making it a superior choice for more demanding and variable environments.
Step-by-step explanation:
The Sikalastic 720/745 system has several advantages over the Sikalastic 390/395 system. One key advantage of the 720/745 system is its higher performance in terms of durability and resistance to abrasion, making it suitable for more demanding applications. The 720/745 system is also noted for its better mechanical properties, which include higher tensile strength, making it more resistant to tearing and elongation. This makes it ideal for use on surfaces that experience high levels of foot traffic or heavy equipment use.
Another advantage is the Sikalastic 720/745's wider service temperature range, ensuring its performance in both extremely cold and hot climates. Furthermore, the 720/745 system often requires fewer coats than the 390/395 system, leading to a faster application process and potentially lower labor costs.
Finally, the Sikalastic 720/745 system is also highly regarded for its excellent chemical resistance, which means it can withstand exposure to a variety of chemicals, oils, and acids that may be present in industrial environments, making it a preferred choice for areas that may encounter such exposures.
