Sodium Etching Solution

AC-711 processing sodium naphthalene solution suitable for surface treatment of PTFE and other plastic products. Such as film, ring, rod and other products. The treated PTFE surface brown, processing depth of 1 ~ 2um, the surface energy is increased from 18day/cm2 to 25-30day/cm2. which will improve the adhesive surface strength to the bonding strength of hydrocarbons, which can use a common adhesive such as epoxy resin, polyurethane resin adhesive, in order to achieve the plastic used to strong acid, alkali, strong oxidizing agents and other occasions, such as all kinds of valves, pipelines, but also can be used to reduce the surface pretreatment of iron and steel surface friction coefficient, such as all kinds of machine tool guide rail, gate chute.
Technical indicators:
Appearance: dark green liquid.
The relative density of g/cm fand.: 0.8 ~ 0.83.
Solubility: tetrahydrofuran., acetone, butyl acetate.
Effective period: 3 to 6 months (sealed), Kaifeng, please run out within a week.
Avoid light and water.
Application method:
Will PTFE products processing, such as thin film immersed in liquid in treatment of 1-2 minutes, washed with acetone to clean; if the single treatment will not need to deal with adhesive side cover closed, etc. after the processing the self-adhesive tear can. Can also be the treatment liquid spraying the surface of the product, after drying, bonding with acetone washed clean after.
