Super Glue (Single-Component Acrylic Adhesive )

Single-component liquid acrylic adhesive is widely used in the fabrication of acrylic letter faces, illuminated panels, and mixed-material signage structures.

Typical Applications

  • Acrylic illuminated letter faces

  • Channel letters and resin-filled signage

  • Mixed-material signage structures requiring high transparency and durability

Key Features

  • Low-odor and low-toxicity formulation, providing a safer and more comfortable working environment

  • Single-component acrylic adhesive, easy to apply with no complex mixing required

  • Self-release without water immersion, improving production efficiency

  • Stable curing performance without strict temperature control

  • UV-assisted curing within approximately 90 minutes under operating temperatures from 10°C to 55°C

  • Excellent thermal resistance, operating reliably from -30°C (cold resistance) to 100°C (heat resistance)

  • Strong resistance to contamination and staining, suitable for long-term outdoor use

  • High resistance to yellowing, maintaining clarity and appearance over time

  • Crack-resistant performance, especially suitable for large-format illuminated letters

AB Glue (Two-Component Structural Adhesive)

AB glue is a two-component structural adhesive designed for permanent bonding and reinforcement in signage fabrication.

It is commonly used for metal letter structures, channel letter frames, and mixed-material signage assemblies.

Typical Applications
