Product assembly

Waterborne Adhesives:

• provide stronger bonding to porous substrates due to deeper penetration.
• provide greater resistance to cold and heat.
• can be formulated for water resistance.
• are economical
• can be sprayed, rolled, or extruded

• have a longer set speed and open time

The basic types of Waterborne adhesives

Emulsions-A solid, often synthetic, resin is dispersed in water by use of an emulsifying agent. The emulsifier allows the solid to remain suspended in the water for protracted periods of time. An emulsion does require agitation to keep the solids suspended. Emulsions have a long shelf life.

PVA-Poly Vinylacetate
PVA is the most common and most recognized adhesive. Commonly known as “White Glue”, it is found in use in paper and cardboard bonding applications.

EVA-Ethylene Vinylacetate
EVA is an upgraded form of PVA that allows for a greater degree of flexibility in the end product.

Acrylic-Acrylics are used most often for pressure sensitive applications such as tapes or labels. Acrylics provide a quick bond with residual tack.

Casein-Casein is a milk-derived protein that has extensive applications in the woodworking industry as well as labeling of glass bottles.

Rubber/Laytex-Natural latex as well as synthetic rubber is cohesive, bonding to a substrate and employed by sticking to itself, as it will remain tacky. Often used in envelope applications.
