Pecora Dynatrol 1-Xl Hybrid Sau Window Tan 12/Cs

20 Oz Sausage, 200 Deg F Flash Point, 2.5 to 3 Hr Setting Time, Mild Odor, Heavy Paste, 1-Part, Non-Staining, Non-Yellowing, Window Tan DynaTrol® I-XL Hybrid Sealant

Dynatrol® I-XL Hybrid is based on a unique hybrid STPU (silyl-terminated polyurethane) differentiating it from the standard Dynatrol® I-XL urethane-based sealant. The STPU chemistry utilized by the Dynatrol® I-XL Hybrid formula allows for a low odor, non-staining, non-yellowing, one-part, moisture curing, gun-grade, isocyanate free sealant. It has been developed specifically for sealing dynamic joints between dissimilar materials, of varying coefficients of expansion and contraction on both porous and non-porous surfaces. It cures to a low modulus rubber with extraordinary adhesion, capable of accommodating joint movement of +/-50% of the original joint width. It does not yellow, crack or craze on long term exposure to UV light.
