Dynatrol I-XL Hybrid is a one part moisture curing STPU specifically designed as a high performance sealant for use in dynamic joints. 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.
Pecora Dynatrol I-XL Hybrid is based on a unique hybrid STPU (silylterminated 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, nonstaining, non-yellowing, onepart, 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.
