Columbac II - Epoxy Resin and Hardner Mix Ratio
Posted by Eugene from Newark, CA, US on May 28, 2009
What is the mix ratio of the epoxy resin and the hardner for the Columbac II?
Each “kit” of backing Columbia supplies comes with premeasured quantities of epoxy and catalyst. However, the ratio for both of our types backings are as follows:
Type of Backing................By Volume...............By Weight
Regular……………………100 / 10.9…………..100 / 6
Hi-Impac…………………..100 / 12.6………… 100 / 7.3
As always, the directions should be currently affixed to each container and they should be followed explicitly.
