Pecora Dynatrol 1 FTH 1.5g

“Dynatrol I-XL FTH is field tintable and 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 FTH formula allows for a low  odor, non-staining, non-yellowing, one-part, moisture curing, gungrade, isocyanate free sealant. 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.”
