Pecora DynaTrol I-XL Hybrid One-Part, Non-Staining, Non-Yellowing Sealant, Precast, 20oz

Pecora DynaTrol I-XL Hybrid One-Part, Non-Staining, Non-Yellowing Sealant, Precast, 20oz

Dynatrol I-XL Hybrid is based on a unique hybrid STPU (silyl-terminated polyurethane) chemistry that allows for a low odor, non-staining, nonyellowing, one-part, moisture cure, 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.
