Know what plasma activation is and how it works

Nowadays, plasma activation process is in great use as it is more fruitful and effective as well. So, for those who don’t know what plasma surface activation is, for them, it is an effective alternate for surfacing polymer by attaching functional groups or polar groups. There are many polymers like polypropylene and polyethylene which are chemically inert and so they do not easily bond with other materials. The main reason behind this is absence of reactive and polar functional group in their structure.

Plasma activation ensures effective and flexible surface modification of metal, glass, plastic, textiles, composed and recycled material. Plasma activation targets surface energy and helps in achieving selectively where needed. Overall, the result is clearly better depending on capabilities of surface.

Working of plasma treatment surface

The working of plasma treatment surface is much different and efficient. Active oxygen and UV radiation species from plasma break separating agents. These agents are then pumped away by vacuum system. Active oxygen species from plasma bind with active surface sites all over material creating surface highly active as bonding agents. The energy specialization and input of surface cause surface more roughen with pump range. The main benefit of this process is that coating is anchored easily to larger area.

Importance of pretreating with plasma

To ensuresuccessful print, coat, paint polymers, bond and metals, surface must meet with few requirements first. It mustbe clean enough and should be sufficiently active suchthat it can form an adhesive bond with coating material easily. Thus, plasma pretreatment take care of these requirements: The reactive species ofplasma transform finest organic layers to gas phase attime of ultra-fine cleaning. Whileon other hand, along with polymers, functional groups which are described above bonded with outer-most molecular layer, thisincreases the surface polarity and prerequisite for adhesive bonding is fulfilled with applied material.

These days, a huge variety of plasma surface activation treating systems is available in market; one of them is SU8 which is in demand. Along with this many other systems are also available which can be purchased accordingly.
