It has the consistency of jam and smells like jam and tastes like jam but is not jam, then what is it? You guessed it, polyurethane resin. As a side note: if it gets to the point where you need me to tell you that polyurethane is bad for you, then I think it’ll come down to natural selection.
Today’s recipe is on how to cook a resin tire, evenly through. Serves 2.
What ingredients you need:
- Tin cured silicon rubber with a hardness grade of 25 or 40A.
- Polyurethane resin with a hardness grade of 80A.
- Measuring cup about 500ml.
- Stirring sticks.
- A plastic container that can fit your print of the tires.
- Dye
- 2x 500g weights per how many prints you are doing at the time.
Directions:
- Put the print of your tires into the plastic container.
- Measure out and accurately mix the correct ratio listed in the technical document.
- Pour the silicon on the print and hold it down with the weights.
- Wait for one to three days for the silicon to cure.
- Once it has cured now you’re ready to cast.
- Once again you want to measure and accurately mix the correct ratio in the technical document.
- Pour the resin into the moulds and put it in a safe place where it can cure. Curing will take roughly the same amount of time as the silicon.
- Now you’re ready to serve.
