The principal advantages for their use are as follows:
1. They are the easiest of the resin systems to mix and apply by using
pour-in-place and self-leveling techniques.
2. Because of their outstanding weatherr esistance, they aree qually
appropriate for indoor and outdoor applications.
3. They are the only system that can be installed at below freezing
temperatures, 258 F( K 4 8 C), without havingt ou se special hardening or catalyst systems.
4. They aret he fastests et andc ure of allr esin systems.T he
