Polyurethane Casting Rubber *Firm* Shore A 80 280g Kit *Ideal for Poly Bushes*
Description
Kit consists of 200g of Part A and 80g of Part B
Approximate Volume 259ml
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. With a very low viscosity making it easy to mix and pour without trapping bubbles. It is excellent for casting decorative objects, production parts, tools, models, patterns, duplicate masters and more.
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.
The fast versions pot life is approximately 6-7 minutes and the casting can generally be de-moulded in 1-2 hours depending on the size and especially the thickness of the casting.
The slow versions pot life is approximately 20 minutes and the casting can generally be de-moulded in 3-5 hours depending on the size and especially the thickness of the casting.
