How to process the material
NEUKADUR PU 173 is sensitive to humidity and has to be processed in a dry atmosphere. Prior to casting, seal open-pored casting moulds as for example wood or plaster of Paris.
Stir the desired quantitiy of fillers into NEUKADUR PU 173 Comp. A and mix the compound thoroughly with NEUKADUR PU 173 Comp. B. Then proceed to casting immediately.
For demoulding we recommend NEUKADUR release agent SE and/or NEUKADUR release spray P 6.
For release agents, please visit our homepage under http://www.altropol.de/and more/release agents.html
Addition of Fillers
By using selected fillers, you can easily produce hard, abrasion-resistant as well as machinable moulding materials. When aluminium powder is used, the cured material can be polished well.
A filling ratio of 100 ¨C 350 p. b. w. of NEUKADUR filler A, NEUKADUR filler B, NEUKADUR filler K, NEUKADUR filler G, NEUKADUR quartz powder SH 500, NEUKADUR filler H, NEUKADUR aluminium powder AS 011 or NEUKADUR filler AL is possible. When the proportion of fillers added is very high, the shrinkage will be minimized.
