Black Fast Cast Resin 250g Kit

Kit consists of 125g of PART A and 125g of PART B 


Total kit volume 231ml


PART A is a black liquid and PART B is a amber liquid that have virtually no odour and react to form a strong, tough, non-greasy polyurethane rigid plastic black in colour. For flexible polyurethane rubbers click here 

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 3-4 minutes and the casting can generally be de-moulded in 30-40 minutes depending on the size of the casting. For longer pot life casting resins click here

The liquid mixture has a very low viscosity of 50 mPas enabling it to flow in fine details and deep undercuts whilst also minimizing bubbles.

Once cured it is the strongest of all our resins, having both a high tensile and a high flexural strength making it excellent for prototypes, scale models, toys and producing detailed decorative objects etc. For a tough, impact resistant, semi rigid material that in thin sections has a degree of flexibility click here

Please view the table at the bottom of this listing for the full technical specifications.
