Akulon (PA6 and PA66)
Vacuum metallization, electroless plating and electroplating are the
techniques that are most frequently used for Akulon.
Predrying of parts before metallization is not always necessary, depending on
the metallization process and the moisture content.
Arnite (PBT and PET)
Vacuum metallizing is the best metallization technique for
Arnite. To improve adhesion, the application of a cellulose primer coat is
desirable. To protect the metal layer, a cellulose topcoat may be used.
Arnitel (TPE)
Vacuum metallizing is the best process for Arnitel.
With regard to the low flexibility of the metal film, it is best not to use
soft Arnitel grades and always run a test first.
Stanyl (PA46)
The most important metallization techniques for Stanyl
are electroplating (3-D PCB's) and
vacuum metallization (reflectors).
In electoless plating of Stanyl, chemical
roughening of the surface can be done by means of a CaCl2 solution at 40 ºC;
etching can also be done using carefully selected concentrations of hydrogen
chloride, chrome-sulphuric acid, potassium hydroxide and lactones.
Xantar (PC and its blends)
Vacuum metallizing,
plating and spraying can all be used
for Xantar PC. Great care must be taken when swelling
solvents are applied to enhance adhesion. Environmental stress cracking
due to molded-in stresses may occur. Stresses can be detected in transparent
Xantar grades using polarized light.
Electroless plating is especially suitable for rubber modified PC grades
and PC/ABS grades (Xantar C).
