500-Series Polyurethane Products

Product catalog summary

Product Overview
3M™ 500-Series Polyurethane Products include a range of sealants and adhesive sealants designed for construction and industrial applications. These products are one-component, moisture-curing, and form permanent elastic bonds with various materials such as plastics, metals, fiberglass, and wood. They offer different Shore A hardness levels, open times, and performance parameters to suit diverse application needs.

Features and Advantages

One-component/moisture curing: Simplifies production with no mixing required.
Bonds dissimilar materials: Provides design flexibility.
Adheres to a wide variety of materials: Allows for multiple uses and design flexibility.
Permanently elastic: Ensures long-lasting bonds.
Fast curing (specific products): Speeds up production.
Paintable after cure: Enhances appearance.
High tensile strength: Offers strong bonds, potentially replacing rivets and mechanical fasteners.
Low modulus/Low Shore A Hardness: Ideal for sealing and bonding materials with different thermal expansion coefficients.
High modulus/High Shore A Hardness: Suitable for high-strength bonding.

Technical Data
Key properties include tack-free time, rate of cure, Shore A hardness, tensile strength, elongation at break, service temperature range, specific gravity, and VOC content. These properties vary across the different products in the series.

Application Ideas

General Industrial and Construction: Suitable for a wide range of applications.
Marine and Specialty Vehicle: Specific products are designed for marine construction and specialty vehicle applications.

Performance Data
Products are resistant to heat, UV, water, and salt spray. They are compatible with water-based paints and require testing with solvent-based paints.

Certifications and Listings

ASTM C920, Type S, Grade NS, Class 25: Certain products meet this standard.
NSF R2 Coating: Available for specific colors.
Federal Railroad Administration and International Maritime Organization certifications: Applicable to certain products.
LEED Credit Contribution: All products contribute to LEED credits.

Directions for Use
Surface preparation involves cleaning and drying surfaces, with optional use of primers for improved adhesion. Application involves using appropriate applicators for cartridges or sausage packs, with specific instructions for loading and dispensing. Cleanup should avoid alcohol to prevent interference with curing.

Storage and Shelf Life
Products should be stored in a controlled environment below 77°F (25°C) to maximize shelf life, which is 12 months for cartridges and sausage packs, and 6 months for larger containers.

Warranty and Liability
3M provides a warranty that products meet specifications at the time of shipment, with limited remedies available. Users are responsible for evaluating product suitability for specific applications.
