Chemical Reactions often require a catalyst and the use of a needed catalyst is a game changer.
Product Overview
The Tech-Bond Catalyst is the activation component of the Tech-Bond Molecular Bonding System. When applied to the bonding interface, the Catalyst creates temporary reactive states that dramatically increase surface energy and allow the Tech-Bond Bonding Agents to form permanent molecular bonds.
Unlike conventional adhesive accelerators that simply speed cure time, the Tech-Bond Catalyst actively participates in the bonding mechanism, enabling bonds to form between materials that are normally considered difficult or impossible to bond.
The result is structural bonds that resist moisture, fuels, vibration, and thermal cycling.
What the Catalyst Does
The Catalyst performs three critical functions during the bonding process:
1. Surface Activation
The Catalyst temporarily raises surface energy, creating reactive bonding sites.
2. Polymer Integration
When used with heat and Tech-Bond Bonding Agents, the Catalyst enables molecular integration between polymers and other substrates.
3. Cure Acceleration
The Catalyst dramatically reduces cure time, allowing bonds to form in seconds while achieving permanent strength.
Our proprietary catalyst, the Activator/Accelerator is a game-changer.
Key Features
• Creates temporary reactive bonding sites (TRS) on the bonding surface
• Enables bonding of difficult substrates including polymers
• Accelerates curing of Tech-Bond Bonding Agents
• Improves bond penetration and surface wetting
• Enables layer-by-layer bonding in structural repair systems
Compatible Materials
When used with Tech-Bond Bonding Agents, the Catalyst enables bonding across a wide range of materials:
• Thermoplastic polymers
• Thermoset polymers
• Elastomers
• Metals including aluminum and steel
• Composite materials
• PTFE-coated fabrics
Role in the Tech-Patch Repair System (TPRS)
Within the Tech-Patch Repair System, the Catalyst is applied between structural layers to activate the bonding interface.
The layer-by-layer Catalyst application allows each Tech-Patch layer to integrate into a single unified structure rather than forming a simple adhesive stack.
This process creates a cross-linked repair structure that is moisture, fuel, and vapor proof and unaffected by thermal cycling.
Typical Applications
• Plastic tank repair
• HDPE pipe repair
• Composite reinforcement systems
• Industrial equipment repair
• Structural bonding of difficult substrates
Why the Tech-Bond Catalyst Is Different
Traditional adhesive accelerators only speed curing.
The Tech-Bond Catalyst actively participates in the bonding mechanism, creating temporary reactive states that allow the bonding agents to integrate at the molecular level.
This difference is what allows the Tech-Bond Molecular Bonding System to achieve permanent structural bonds across materials that normally resist adhesion.
System Components
The Tech-Bond Molecular Bonding System consists of:
• Bonding Agents (SI Green, SI Blue, SI Black)
• Catalyst (Activator / Accelerator)
• Poly Prep surface conditioning system
Together, these components enable molecular bonding across an extremely wide range of materials.
