In order for epoxy systems to harden, the resin and the hardener must undergo a chemical reaction. Mixing is an important step in using epoxy. In order for the chemical reaction to take place smoothly, the resin and hardener must be dispersed homogeneously in the mixture. This situation depends on good mixing. In mixtures that are not made homogeneously, curing problems occur in local areas or in all areas.
Pay attention to the following items for a correct mixture;
1- Absolutely comply with the mixing ratios that belong to the type of resin you use. Otherwise, it will not matter how well you have made the mixture and you may still experience curing problems. “At What Mixture Ratio Should I Mix?” You can review our article titled.
2- Make sure that the container and mixing apparatus in which you will mix are clean and dry.
3- Place your mixing bowl on the precision scale and zero your scale by taking the container tare.
4- First, pour the required amount of calculated epoxy hardener into the tared container and reset your scale again by taring.
5- Pour the required amount of calculated resin on the container full of tared hardener. Do not forget to close the caps of the resin and hardener you use at this stage.
6- Start mixing the weighed resin and hardener with a suitable mixing apparatus (wooden stick, metal spoon, glass drumstick, mixer mixer tip, etc.).
7- Mix the mixture at a speed of approximately 100 rpm for at least 2 minutes. As the amount of material you are mixing increases, you may need to increase your mixing time or mixing speed. As soon as you start the mixture, there will first be a blur in the system and the mixture will start to become transparent again as the mixture continues. After mixing until completely transparent, if you don’t see a vein pattern following your blend stick, the first step of the blend is complete.
8- Transfer the first stage of the mixture by scraping it to another clean container and mix again.
9- Before using the mixture you have mixed for the second time, let it rest for a while considering the working time of the product and then you can complete your process by pouring it into the area you will apply.
