Thermal Expansion Polyurethane Adhesive Caulking Sealer | Flexible Bond | Multi-Surface | ELASTOBOND 70

Two-Component Elastomeric Thermal Expansion Polyurethane Adhesive Caulking Seale

Thermal Expansion Polyurethane Adhesive Caulking Sealer | Flexible Bond | Multi-Surface | ELASTOBOND 70. ELASTOBOND™ 70 is a high-performance, two-component, 100% solids elastomeric polyurethane adhesive designed for applications requiring flexibility and strong adhesion. This adhesive effectively bonds substrates with differing thermal expansion rates and withstands significant thermal shock. Its thixotropic formulation enables vertical application without sagging, making it ideal for demanding industrial and construction environments.

KEY FEATURES & BENEFITS:

• Shore A 70 Hardness: Provides a balance of flexibility and structural integrity.
• Excellent Flexibility: Maintains adhesion under mechanical stress and dynamic movement.
• Highly Thixotropic: Ideal for vertical and overhead applications without dripping or flow.
• Weather Resistant: Withstands exposure to environmental conditions, ensuring long-term performance.
• Thermal Shock Resistant: Maintains bonding strength even under extreme temperature fluctuations.
• High Impact Resistance: Absorbs and distributes impact energy without failure.

APPLICATIONS:

ELASTOBOND™ 70 is engineered for bonding a variety of substrates, particularly those exposed to thermal expansion differences and dynamic loads. It is widely used in:

• Industrial and construction applications requiring durable, flexible bonding.
• Assembly of dissimilar materials subject to mechanical stress.
• Structural bonding where resistance to temperature variations is critical.

SUBSTRATE COMPATIBILITY:

ELASTOBOND™ 70 provides excellent adhesion to:

• Metals: Stainless steel, galvanized steel
• Elastomers: Rubber
• Concrete: Ideal for structural bonding applications
• Plastics: Adheres to certain types with proper surface preparation

APPLICATION GUIDELINES:
For optimal adhesion, surfaces should be clean, dry, and free of contaminants. Surface preparation methods such as sanding, degreasing, or priming may be required depending on the substrate type.

STORAGE & SHELF LIFE:
Store in original, unopened containers at room temperature in a dry environment. Properly stored, ELASTOBOND™ 70 maintains its performance characteristics within the recommended shelf life.
