After complete curing, Weicon Plastic Metal HB 300 will be completely hard. Test results found it to have a Shore D Hardness of 85, a very high compressive strength (100 MPa) and a mean tensile strength of 127MPa (all tested at 25ºC in accordance with DIN 53281-83 requirements).
This high temperature grade of plastic metal is used in applications where continuous temperatures fall between -35ºC and 200ºC (with spikes up to 280ºC).
Weicon Plastic Metal HB 300 is offered in 1kg kits that contain the appropriate portions of resin and hardener as well as a pair of disposable gloves and a plastic mixing spatula. To make mixing simple, space has been left in the resin container so that all of the hardener can be added and mixed.
