Berkland Acrylic Bonding Cement
Berkland’s [4 oz] Acrylic Bonding Cement is designed specifically for plexiglass and acrylic sheets. The brand promotes a precision bonding approach with a water-thin formula that flows into tight joints, delivering a clean, strong bond on acrylic and other plastics. The fast-setting formula begins to set within minutes, enabling quick repairs, fabrications, and production work. After curing, the bond dries crystal clear, preserving the transparent look of plexiglass. This cement is ideal for edge joints, small fabrications, or repairs in signage, displays, or protective shields where optical clarity matters.
- Precision bonding with a water-thin consistency
- Fast-setting—initial bond in minutes; full strength after curing
- Crystal-clear finish for transparent acrylic sheets
- Designed for acrylic, plexiglass, and similar plastics

Buying Guide
Choosing the right plexiglass adhesive hinges on bond type, clarity, cure time, and application method. Acrylic cement provides a solvent-based, strong, clear bond ideal for plexiglass edges and joint lines, though it can require careful handling to avoid crazing. Cyanoacrylate glues (CA) offer rapid bonding and versatility across plastics, including acrylic, but may appear slightly brittle under flexing stress. Glass- and acrylic-specific formulas, or multi-material glues, can balance speed with transparency, which is crucial for visible plexiglass installations.
Key purchase considerations
Bond type and compatibility should align with your plexiglass project. For permanent, high-clarity joints, acrylic cement or CA glues designed for acrylic often outperform general purpose glues. If you expect stress or movement, look for formulations with higher impact resistance or flexible hardening properties. Consider cure time—quick-drying options save time, but slower cures can yield stronger long-term bonds if properly clamped and cured.
Clarity, finish, and handling
Opt for adhesives that dry crystal clear and resist yellowing over time to maintain the transparency of plexiglass. Application aids like precision tips, anti-clog caps, and controlled dispensing improve accuracy on small or delicate joints. Anti-clog features help keep the nozzle usable after storage, reducing waste and maintenance.
Safety and storage
Check safety data for fumes, skin contact risk, and ventilation requirements. Many acrylic and CA glues provide MSDS and safety reports. Store adhesives upright in a cool, dry place away from heat and moisture to preserve shelf life and prevent premature curing.
Use-case guidance
For hobby projects or small repairs, CA glues offer speed and simplicity. For edge-bonding and long-lasting plexiglass assemblies, solvent-based acrylic cement often yields stronger, clearer joints. For mixed-material assemblies (glass, metal, wood with plexiglass), select glues labeled for multi-material use and verify surface preparation requirements (clean, dry, and free of oils).
