Our Plastic Metal BR is a two-part epoxy resin filled with bronze. This specialised repair compound has a pasty viscosity when it’s mixed and sets hard with physical properties. The cured putty has a bronze colour and it is widely used for repairs and resurfacing of bronze parts and surfaces.
This high-quality type of plastic steel is manufactured by Weicon in Germany and widely used in various industries around the world. It is especially popular in the marine sector and is registered with both the IMPA and ISSA (reference numbers available on the specifications tab).
More details on the various attributes and capabilities of Plastic Metal BR are included below:
Based on epoxy resin with bronze filler, Weicon BR Epoxy Plastic Metal offers something of a combination of the properties of bronze and epoxy. The most obvious of these is its colour (bronze, though it can be painted) while others are more subtle.
This grade of Plastic Metal is slightly softer when cured than many of our steel filled grades (such as our Plastic Metal A). It is also non-magnetic.
Once cured, this epoxy repair compound is quite hard. It has a shore D hardness rating of 75 and a pressure rating of 95 MPa.
Bending resistance is measured at 35 MPa.
The entire range of Weicon Plastic Metal products has good chemical resistance. They are all resistant to most oils, greases, many types of fuel and water.
They also withstand attack from most diluted acids and many other common industrial fluids. More information on resistance to specific chemicals is provided on our Plastic Metal BR TDS.
Once cured, this quality epoxy compound can be used in applications where temperatures are between -35°C and +120°C.
Weicon Plastic Metal BR is a two-part compound with a 1:1 mix ratio. Room has been left inside the larger of the two containers to let you add the entirety of the activator liquid and mix the two parts thoroughly. This removes the need for measuring and ensures a correct mix ratio is achieved each time.
Once mixed, Plastic Metal BR has a pasty nature that allows it to be accurately applied to fill holes, gaps or other deep crevices.
Pot life for the mixture is 60 minutes (200gm at 20°C). After 16 hours, the compound will be able to bear mechanical loads. After 24 hours full cure will have been achieved.
