Explaining our chemistries:
Acrylics: The viscosity of acrylic adhesives allow for very easy dispensing by hand while maintaining a non-sag characteristic. Also, acrylic adhesives change color during cure, giving a visual indication that the adhesives is cured. Another key property of acrylic adhesives is that they can have a long room temperature open time but once they begin to react, they quickly reach handling strength. Other adhesive chemistries are not able to match this cure profile.
Urethanes: Urethane adhesives are offered as either one and two component systems. Also, urethane adhesives are formulated with much lower viscosity compared to epoxy or acrylic adhesives. Urethanes are inherently sensitive to moisture which reacts with the isocyanate in the system. Care should be taken to avoid high humidity conditions and moisture in the substrates.
Epoxies: Epoxy adhesives generally tend to be viscous liquids or pastes, although self-leveling liquids are available. In general, epoxies are less sensitive to slight variations in mix ratio. Also, epoxy adhesives offer long open times, allowing for repositioning and assembly of complex shapes. Final properties develop within 24 hours at room temperature.
