Best Practices for Elantas (Altana) Conathane UF-3

*See Terms of Use Below
1. Mixing
  
  Part A and Part B should be adjusted to a temperature of 25 ± 2°C prior to mixing.
  
  Containers used for mixing should be glass, unlined metal, or polyethylene-coated paper.
  
  Mix Ratio by weight, (Part A/Part B) - 100/90
  
  Weigh the two components into separate containers, then pour together and mix thoroughly for 10-15 seconds using high-speed agitation. (High speed laboratory drill presses, fitted with a turbine or propeller-type agitator, have been used successfully.)Pour immediately into molds that have been coated with a CONAP® Mold Release and preheated to 30-40°C. Complete pouring within 30-40 seconds after mixing. Foaming is complete within approximately three minutes and the foam can be handled in 5 to 7 minutes. The volume increase is eight to ten fold.
