Information

Kit consists of 2kg of PART A and 500g of PART B

Total kit volume 2.3 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 has a similar hardness to natural rubber used in vehicle bushes/bump stops, seals and matting etc so can be used in the production of polyurethane replacement parts commonly known as poly bushes. For stiffer uprated sports bushes our firmer Shore A80 rubber can be used.

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 100:25 by weight.
