What Are Dot Volumes and Bead Volumes?
When applying an adhesive, a dot is a droplet or spot of the substance, and a bead is a glue line. For both, you should carefully manage adhesive volume as well as the dot or bead locations to ensure precision. Changing the nozzle on your application equipment can give you greater control, as needed, over the volume of adhesives you use and where the adhesives go. Knowing your approximate dot and bead size will help you determine how much adhesive you need.
What Are Viscosity Scales? How Are They Useful?
Viscosity scales cover the range of a fluid material’s flow resistance. High values on the scale indicate a thick substance with high flow resistance, and lower values signify a thin fluid with a faster flow. Choosing an adhesive for its uncured viscosity can help you find the right one for your application. Low-viscosity adhesives are ideal for covering a greater surface area in a thin glue film, but they can be runny. High-viscosity adhesives are more difficult to spread, but they can offer superior bonding strength. Remember that heat affects a fluid’s viscosity, so factor in temperature when selecting the optimal viscosity.
