Introducing Seal Bond High Tack Mastic: A Game-Changer in Pressure-Sensitive Adhesives

Seal Bond set out to solve a common challenge in the adhesive market—pressure-sensitive adhesives that fell short in performance, versatility, and safety.

The result? High Tack Mastic—an advanced, solvent-free, moisture-cured adhesive with unmatched adhesion and flexibility.

The Challenge

Traditional adhesives like solvented butyl and water-based acrylics weren’t cutting it—so we set out to build something better. The innovation needed to:

  • Create a high-tack, pressure-sensitive, moisture-cured adhesive
  • Eliminate solvents to reduce odor, flammability, and substrate degradation
  • Ensure shipping flexibility—even by air or into regulated regions
  • Outperform water-based adhesives in tack speed and elasticity
  • Make it easy to apply by extrusion, roller, or trowel

High Tack Mastic

Seal Bond’s answer to the industry’s issue is a revolutionary adhesive platform lovingly referred to as “bubble gum.” It’s a single-component, permanently tacky adhesive that provides strong, pressure-sensitive adhesion across a wide variety of substrates, including traditionally tricky low-surface-energy materials.

High Tack Mastic doesn’t just bond—it also seals out water and maintains long-term flexibility, ensuring durability even under environmental stress. It’s easy to apply, requires no mixing, and sets quickly, making it a powerful tool across industries.

 

 

Why High Tack Mastic Works 

Here’s how High Tack Mastic stands out from anything we’ve made before:

  • High Tack Mastic delivers permanent tack, outstanding elasticity, and pressure-sensitive adhesion for many substrates. 
  • It stays flexible, blocks water, and simplifies application without any solvents, mixing, or hassle.

“The product provided excellent water-stopping and sealing capabilities for our applications.”

 

The Results

This adhesive makes difficult bonds easy. Plus, it keeps water out! Other standout features include:

  • Superior adhesion to low surface energy and hard-to-bond substrates
  • Seamless integration into multi-material systems (e.g., multi-layer roofing)
  • Effective water barrier at the glue line
  • Exceptional elasticity and long-term flexibility
  • Solvent-free formula safe for shipping anywhere
  • No-mix, easy-to-use application straight from the pail
  • Fast tack with roller, trowel, or spatula

“Exceptional Flexibility – once cured, the adhesive offers flexibility, allowing it to adapt to movement at critical sealing points in the roof system. This ensures long-lasting, reliable performance, even in the most challenging conditions.”
