Casting PU plastic Resin designed for casting lures.

[benniejordaan]

Feather lite was specifically designed for lure building an has buoyancy characteristics.

It is NOT available in South Africa so I had a few pack brought in specially for us. There are 2 left... The cost is R185 + postage per pack.

I have 2 left!

Feather Lite® Liquid Plastic - It Floats In Water! [align=center] 



[/align] Feather Lite® is a heavily filled low-density urethane casting resin. Cured plastic is lightweight (it floats in water!) and has a much lower density than other casting resins. Feather Lite® features a convenient 1A:1B by volume mix ratio and mixes easily (pre-mixing of parts A & B is necessary).Cured plastic is strong and can be carved, machined, drilled, sanded, etc. Feather Lite® can be pigmented with SO-Strong® color tints prior to casting and finished castings can be painted. And because this product is low-density, it yields more plastic per pound/kg. than other casting resins, the cost per casting is low.

Feather Lite® can be used for a variety of art or industrial design related applications including reproducing sculpture, making fishing lures, prototype model making, casting doll heads and figures, and many more applications.

From what I remember from my youth, Feather Lites were made by Durex :dude:

Are u using RTV moulds for that? If so, where do you get it?

Edit: Oh, and what is the volume of the PU

You need to make the moulds. Use silicone (Mouldmax 30) available from AMT composites.

The Resin is a 1kg packs. To give you an idea, my sardine uses around 60 grams max so good for around 15 lures maybe more...

Smooth-on feather lite has a density of 0.67g/cm3, so floats. It is an equivalent density to beech. It has a viscosity of 400 cps.

Just to explain feather lite...

It is basically a standard PU resin but has had micro balloons premixed into it. You can buy resin and micro balloons to mix yourself but the biggest problem is consistency. You will never be able to mix micro balloons into resin and get a consistent S.G. The other problem is you do not want to breath micro balloons in. It is like glass! And thirdly, micro balloons absorb moisture... Resin hates moisture which will cause bubbles in your cast.
