Filler Polyurethane
With this Polyurethane Filler (based on Aluminum tri-hydrate) you can increase the maximum casting thickness of the Polyurethane casting system D80 Set , into 80 mm instead of 30 mm.
PU filler that is added to a polyurethane casting system increases the rigidity of the PU (In PU casting system D80, for example, the shore will increase from 70 Shore A to a maximum of 85). The maximum casting thickness of the PU casting system D80 is 100 mm instead of 30 mm when you add this filler.
This filler is self-extinguishing and gives this property partly with the PU in which the filler is mixed.
The addition of PU prolongs the processing time of 5 to 10 minutes and increases the demould time from 50 minutes to 180 minutes. A small amount of filler will make the PU stronger. Too much filler, however, makes the PU brittle (but increases stiffness).
- Extends the processing time
- Pour Thickness increase to 80mm
- Flame retardant effect
Processing
The maximum ratio in a normal polyurethane casting system is "Polyol(A):Isocyanate(B):PU filler" is 1: 1:3
Shelf life
If stored in a dry location this filler has an indefinite shelf life.
