Technovit® 4000 is a fast curing, cold polymerizing, three-component resin, which is based on a modified polyester, and it is available in the form of powder, liquid I, and syrup II. The color is white opaque.
Very low viscosity; monomeric styrene which penetrates rapidly into the tissues. It is soluble in ethanol and acetone. The infiltration and embedding can be done by styrene alone, and there is no need to dilute it with solvents. Polymerization can be done either by UV light (340-400nm) or heat (60°C) within 2-3 days without benzoyl peroxide added; 24 hours with 1% benzoyl peroxide added as a catalyst.
