L2E Etch Resist coating is an alkali soluble thermal etch resistant paint suitable for acid etching and acidic plating baths. It’s excellent print characteristics and strong blue color facilitate quick inspection. This coating can be removed with CO2 and fiber laser systems.
L2E Etch Resist coating has a high resistance to attack by most acidic based electrolytes and is readily stripped in dilute caustic containing solutions.
FEATURES AND BENEFITS
- Excellent surface finish
- Quick drying/minimizing resist
- High etching resistance
- Easily stripping in caustic
Before applying L2E Etch Resist coating ensure surface of material is clean, dry and dust free
For spray application mix L2E Etch Resist coating with standard thinners 50/50.
SCREEN PRINT APPLICATION
For screen print application L2E Etch Resist coating can be applied at the viscosity it is supplied. Polyester mesh ranging from 180-250 per inch or stainless steel ranging from 250-300 per inch are recommended. Too coarse a mesh will give unnecessarily thick films, which will result in smearing.
For best results this resist requires drying at 80 ºC (170 ºF) for 15-20min.
Over curing (>120ºC) of the resist should not impair stripping or cause brittleness.
L2E Etch Resist coating is readily removed using dilute caustic containing solutions.
