Spray Kontakt Positiv 20
KONTAKT CHEMIE Positiv 20 is a classic liquid photo-resist for a wide variety of applications. The product can be applied anywhere where patterns must be transferred directly onto working materials for processing by etching, electroplating, etc.
Typical applications are the production of printed circuit boards, a range of photo-lithographical processes on metals, glass and suitable synthetic materials.
The lacquer is at its most photo-sensitive at close ultra-violet range (UVA). The lacquer should therefore be applied in yellow light. Windows can be darkened with yellow Plexiglass (e.g. Röhm Darmstadt, Type Amarelo 303). KONTAKT CHEMIE Positiv 20 is resistant to oxidizing agents, ammoniacal to strongly acidic solutions. Coats of Positiv 20 which are no longer required can be easily removed (stripped) by solvents (Ester, Ketone) or 10 to 30 % sodium or potasium hydroxide aqueous solution.
