Description
Dynatrol II Self-Level Elastomeric Sealant is a versatile, non-sag sealant designed for a broad range of applications, ensuring a durable, watertight bond between various building materials, regardless of their surface textures, porosities, or expansion coefficients. It is particularly noted for its ability to handle structural movement exceptionally well, allowing 50% in extension and 50% in compression without failure, making it suitable for both dynamic and static applications.
Product Advantages:
- Tenacious Bonding: Creates a strong, watertight seal across different materials.
- Fire Rated: Includes a four-hour fire and temperature rating for wall and floor systems when used with Ultra Block
- or mineral wool fire safing.
- Durability: Handles significant structural movements without breaking down, supporting up to 50% movement in both extension and compression.
- Versatility in Application: Suitable for a variety of construction needs, including areas requiring fire-resistant properties.
Fire Safety and Compliance: Dynatrol II’s designs have been fully tested and classified by Underwriters Laboratories, making it a reliable choice for projects requiring stringent fire safety measures.
Limitations:
- Not suitable over existing acrylic coatings without testing.
- Should not be used as a cap, heel, or toe bead in glazing systems using high-performance glass or acrylic polycarbonate sheet.
- Avoid use in areas exposed to harsh chemicals or where light colors may yellow under interior conditions.
Technical Specifications:
- Meets Federal Specification TT-S-00227E, Class A, Type II; ASTM C-920, Type M, Grade NS, Class 50.
- Designed to accommodate joint widths calculated to allow for significant thermal and material movement, ensuring long-term performance.
Installation Requirements:
- Surface Preparation: Surfaces must be dry and clean, free from any contaminants. Nonporous surfaces like glass or metal should be wiped clean with a solvent.
- Priming: Generally not required on glass or anodized aluminum and is often unnecessary on most other common building substrates.
