Usually pliable, malleable or liquid before being cured, thermoset resins are then designed to be molded into their final desired shape. Once hardened and molded into their final shape, these resins cannot be reheated or melted and shaped differently.

Tuesday, March 6, 2018

Stormwater skimmers are not something that most think of, but it holds a very important job. These are commonly found in retention ponds, and their purpose is to stop contaminants (such as oil, grease, and other floating factors) from getting into our natural bodies of water.

Due to the typical maintenance of the land, specifically mowing of the grass, this has caused damage to many skimmers thanks to the tractor mowers used. This has become a constant problem and always causes breakage some way or another, so how can it be fixed? The solution is easy; it’s the iSkimmer.
