This small purple glow solves a problem that has cost manufacturers millions.
Geometry, tolerances, and material selection all play important roles in plastic manufacturing, but one factor quietly determines whether coatings, adhesives, inks, or overmolded materials actually stick: surface energy.
At ADIS Tachov s.r.o., we work with polymers every day that behave very differently at the surface level. Materials such as PP, PE, and POM have naturally low surface energy, causing adhesives to bead up rather than wet the surface properly. Others, including PC and PA, bond more easily but still require controlled preparation to ensure long-term reliability.
To address this, we can apply surface activation techniques such as plasma, corona, or flame treatment. These processes modify the outer molecular layer of the polymer, increasing polarity and improving wettability.
Some polymers require aggressive activation methods to achieve reliable bonding, while others benefit from a combination of mechanical roughening and specialized chemical primers to overcome inert surfaces.
This level of detail, and a deep understanding of material-specific behavior, highlights why selecting the right manufacturing partner matters. By engineering surface energy from the start, we help customers achieve stronger bonds, more durable assemblies, and more predictable production outcomes.
What surface preparation method has delivered the most reliable adhesion results in your experience: plasma, corona, flame treatment, primers, or something else?
