Description

Dynatrol I-XL Hybrid Sealant is a state-of-the-art, hybrid STPU (silyl-terminated polyurethane) chemistry-based sealant designed for diverse and dynamic joint applications. This one-part, moisture-cure, gun grade product is engineered to provide exceptional adhesion across both porous and non-porous surfaces. It cures to a low modulus rubber capable of accommodating significant joint movement (±50%), and is formulated to remain stable under UV exposure without yellowing, cracking, or crazing.

Key Features and Benefits:

Non-Staining and Non-Yellowing: Ensures aesthetic integrity in visible applications.
Highly Flexible: Maintains elasticity and movement capability of ±50%.
Fire Rated: Suitable for use in UL fire-rated joint systems, enhancing safety.
Low VOC and Isocyanate-Free: Meets environmental safety standards across all 50 states.
Excellent Adhesion: Bonds effectively to green concrete and other common construction materials.
Paintable: Compatible with high-quality moisture-permeable coatings.
Jet Fuel Resistance: Ideal for demanding environments including airport construction.

Applications:

Dynatrol I-XL Hybrid is highly versatile for both interior and exterior applications, including window and door perimeters, expansion joints, and in settings requiring fire resistance or chemical durability.

Installation Tips:

Surface Preparation: Surfaces should be clean, dry, and free of any contaminants to ensure optimal adhesion.
Joint Design: Adheres to a 2:1 width-to-depth ratio for dynamic joint conditions to maintain sealant performance.
Tooling: Applied sealant should be tooled to achieve a smooth finish and ensure full contact with joint surfaces.

Limitations:
