Silmark CART is a 2-part addition curing silicone casting compound in a cartridge. Silmark CART (gray) has a high pigment content to ensure an optimal sharpness of the casted impression under the microscope.
On the front side of the cartridge a mixing tip is placed. When the cartridge has been mounted in the dispenser equal parts of the base and harder paste are squeezed through the mixing tip and simultaneously mixed by operating the trigger. The mixed compound is directly applied to the toolmark with the mixing tip.
This casting material is very user friendly. The cast itself is stronger than one made with the Silmark packaged in a tube (condensation curing). The shrinkage after curing is also smaller.
