Preparing

CP307 Epoxy Resin should be mixed with its Hardener at a ratio of 100 parts of resin to 100 parts of hardener, by weight. Be careful not to use the wrong component when measuring out. You must maintain the correct overall ratio of resin to hardener to ensure a proper cure. Failure to do so will result in a poor or only partial cure of the resin, greatly reduced mechanical properties and possibly other adverse effects. Under no circumstances add ‘extra hardener’ in an attempt to speed up the cure time; epoxies do not work in this way.

Processing

Only weigh out and mix as much resin as you can use within the pot life. Weigh or measure the exact correct ratio of resin and hardener into a straight sided container. Using a suitable mixing stick begin to mix the resin and hardener together to combine them completely. Spend at least one minute mixing the resin and hardener together, paying particular attention to the sides and base of the container.

Remember:

Any resin that has not been thoroughly combined with hardener will not cure. Once you have finished mixing in one container, it is good practice to transfer the mixed resin into a second container and undertake further mixing of the resin using a new mixing stick. Doing so will eliminate the risk of accidentally
