Information

Kit consists of 800g of PART A and 320g of PART B

Total kit volume 1.024 Litres


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, flexible polyurethane rubber white in colour. This product is firmer in hardness compared to natural rubber used in vehicle bushes/bump stops, seals and matting etc so can be used in the production of stiffer uprated polyurethane replacement parts commonly known as sports poly bushes. To produce parts in a similar hardness to the original natural rubber use our Shore A65.

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. We have a range of compatible colour pigments here

This product has a mixing ratio of 100:40 by weight.
