Notes and Recommendations

Dynatrol® I-XL Hybrid is a one part moisture curing STPU specifically designed as a high performance sealant for use in dynamic joints. Dynatrol® I-XL Hybrid is based on Pecora’s unique hybrid STPU differentiating it from the standard Dynatrol® I-XL urethane-based sealant. The STPU chemistry utilized by the Dynatrol® I-XL Hybrid formula is a one-part, moisture curing sealant that has been developed specifically for sealing dynamic joints on both porous and non-porous surfaces. It cures to a low modulus rubber with extraordinary adhesion capable of accommodating joint movement of ±50%. Dynatrol® I-XL Hybrid does not yellow, crack, or craze under long term exposure to UV light.
