Epoxy Resin Guide (3)
Information about Different Viscosities:
Thicker layers can easily be cast with particularly low-viscosity resin variants. Since this resin does not heat up as much during curing, thicker layers can also be cast. You can remove air bubbles from the still liquid epoxy resin layer by gently blowing with a hot air dryer or a suitable Bunsen burner.
More viscous resin such as laminating resin should not be poured thicker than about 1 cm. Air bubbles rising in the material are very difficult to get to rise and escape because of the highly viscous consistency.
Tip: You can usually find the most important information clearly stated in the manufacturer’s information on the product packaging. As a rule, this information should also tell you what total amount of material can be used in one operation without problems.
A very important factor when working with epoxy resins is the so-called processing time. It is also called pot life or open time by some people. These terms are used to describe the time span within which the resin can be processed after mixing the two components (resin and hardener).
