Load-bearing anti-vibration pad NonBuren Tack Gel

elastomeric

Overview
TACK GEL (NonBuren Tack Gel) is a self-adhesive polyurethane gel sheet engineered for anchor-free seismic restraint and anti-tip protection. It provides cushioning and strong tack to secure equipment without anchor bolts, avoiding floor damage. The product is plasticizer-free and low-outgassing, making it suitable for cleanroom environments. An outdoor-grade version (Tack Gel EX) is available for UV and rain resistance.

Key Features

• No anchor bolts required — no bolt marks or holes on the floor
• Sheet sizes selectable to match machine footprint and weight; cut-to-size on site
• Reusable: adhesive properties recover after washing with water
• Plasticizer-free — prevents chemical migration and surface degradation
• Available in multiple thicknesses (t3, t5) and models (NTG, NTCR)
• Selected for “Kansai Monozukuri New Selection 2013”

What is Anchor‑Free Seismic Restraint?
Anchor-free seismic restraint secures equipment by placing a tacky, load-bearing sheet beneath the unit instead of installing anchor bolts. NonBuren Tack Gel adheres to both equipment base and floor surface via its innate tackiness, providing lateral resistance without leaving adhesive residue or requiring special removal tools (patented). The sheet conforms to mild surface irregularities and can be repositioned or washed for reuse.

What is NonBuren Tack Gel?
Derived from the NonBuren anti-vibration product line, NonBuren Tack Gel is a polyurethane gel sheet optimized for hardness and tack balance. It combines vibration damping similar to NonBuren 30-degree hardness with enhanced surface adhesion to act as an earthquake‑resistant mat and anti-tip fixative while remaining manageable for installation and maintenance.

Strong Adhesive
Tack Gel exhibits high adhesive strength once applied yet is designed for practical removal without specialized tools (patented). Being plasticizer-free eliminates chemical migration risks; cleaning with water restores adhesion for repeated use.

Seismic and Vibration Performance
Material properties mirror the damping performance of NonBuren (30° hardness), reducing transmission of small vibrations to secured equipment and contributing to tilt resistance under seismic loads when sized and positioned according to calculated moments.

Outdoor and Water Resistance
Tack Gel EX is formulated for outdoor use with tested resistance to UV and rain, suitable for applications such as securing gravestones, solar panels and outdoor signage. Usage conditions and selection guidance apply.

Example Applications

• Securing solar panels and other outdoor installations (use EX where required)
• Fixing shop signs, banners and displays without drilling
• Seismic restraint between tiers in multi-layered gravestones
