Furnace & Scale
The most common way to determine the percentage of fiberglass and resin in a laminate is to use a high-temperature oven. We use a Cress electrical industrial furnace model #C401. These models are designed for those users who require automatic temperature controlled furnaces from 250° F to 2250° F.
The sample is placed in a ceramic crucible and then the weight is measured before and after the resin is baked out of the laminate at over 1,000°F.
You can obtain reliable results weighing a cured sample of the laminate on a accurate scientific scale. We use a Sartorius: Entris® specially designed to deliver effective and reliable weighing results in our daily work.
