White Fast Cast Polyurethane Liquid Plastic Casting Resin For Toys And Figurines
Product Description
PART A is a cream liquid and PART B is a amber liquid that have virtually no odour and react to form a strong, tough, non-greasy polyurethane plastic white in colour, the colour of the cured plastic can be changed with the addition of a colour pigment to part A prior to mixing the two components.
This product has a simple mixing ratio of 1:1 by weight. Please note the two liquids have different densities hence different volumes which is why the mixing ratio is equal parts by weight not volume.
The pot life is approximately 5 minutes and the casting can generally be de-moulded in 30-45 minutes depending on the size of the casting.
Applications
Once cured it has both a good tensile and a good flexural strength making it excellent for prototypes, scale models, toys and producing detailed decorative objects etc.
Features
Fast forming speed
Easy to paint/color
Fine appearance performance
Tasteless and easy to produce
Good mechanical properties

How to use
1. Mix A:B 100:100 by weight. Degas with vacuum chamber (check
time).
2. Insert into pressure chamber for about 10 minutes.
3. Demold in 30 minutes, if item thickness is thin, may require
longer time before demold.
Tips
1. PU resin will react faster when room temperature is higher. If
you think it cure too quickly, you can put PU resin A and B into
refrigerator.
2. Once pour required PU resin, tighten the cap quickly.
This product has low viscosity and has great fluidity.
