Silyl Modified Polymers

Of the sealant types presented here, Modified Polymers represent newer technology. Modified Polymer adhesive sealants have many of the characteristics of polyurethane and silicone, and are especially useful in situations where you work with a variety of substrates that are porous and non-porous. Modified polymer technology has also enabled a completely clear sealant adhesive (rather than translucent).

Modified Polymer technology is available in the following products;
Soudal T-Rex
Simson ISR 70-05
