TECHNICAL DATA SHEET 1/2 TRANSPARENT 21 Ref. : 20795 1. GENERAL DESCRIPTION Solvent based transparent spray for paper documents. 2. FEATURES TRANSPARENT 21 makes paper with circuit diagrams, tables, etc, transparent and therefore permeable to visual light and UV-light. 3. APPLICATIONS TRANSPARENT 21 makes paper documents translucent, allowing them to be used directly for the production of printed circuits with the positive photo resist POSITIVE 20. The transparent spray therefore replaces time-consuming repro work. 4. DIRECTIONS To produce transparent paper documents, spray these generously with TRANSPARENT 21. Transparency is retained at room temperature for 20-30 minutes and needs then to be refreshed. When producing printed circuits, TRANSPARENT 21 can be sprayed directly onto the plate coated with the photocopy lacquer POSTIVE 20. Then place the circuit document with the printed side and press down gently. Remove air bubbles by smoothing down. Then process (weighting down with a glass plate can be omitted). To develop the processed exposed board, TRANSPARENT 21 should be removed under running water. TRANSPARENT 21 contains flammable solvents, therefore keep away from ignition sources when using. A safety data sheet (MSDS) according to EU directive 97/112 is available for all CRC products. 5.
