Rigid Foam Two Pound Density
Polyurethane foam, 2 lb density. Also known as A-B foam. Mix two equal parts of Part A and Part B and compound will expand about 25 times to form a rigid mass of foam. Not the same as the spray foam you get at the hardware store. Doesn't form a consistent skin and not especially strong. Great for foam fill for watercraft. Water blown. A 12" x 12" x 12" block of this stuff will weigh about two pounds. A kit consists of two equal volumes of material. For example, a quart kit will contain one quart of part A and one quart of part B.

Rigid Foam Three Pound Density
Polyurethane foam, 3 lb density. Also known as A-B foam. Mix two equal parts of Part A and Part B and compound will expand about 20 times to form a rigid mass of foam. Not the same as the spray foam you get at the hardware store. Doesn't form a consistent skin. Stronger than the 2 pound stuff. Great for making foam armatures on which to sculpt. Water blown. A 12" x 12" x 12" block of this stuff will weigh about three pounds. A kit consists of two equal volumes of material. For example, a quart kit will contain one quart of part A and one quart of part B. Doesn't expand as much as the two pound kits so the material won't go as far.

Soft Polyurethane Foam
Polyurethane foam, about 3 1/2 lb density under ideal conditions. Also known as soft foam. Mix proportionate parts of Part A and Part B and compound will expand to form a soft mass of foam. The same kind of foam that you would find in a couch cushion. Forms a fair skin, great for filling masks, stunt props or body parts for display. Water blown. A 12" x 12" x 12" block of this stuff will weigh about three and 1/2 pounds. A kit consists of two unequal volumes of material. For example, a quart kit will contain one quart of Part B and about half of much of Part A. Rough mixing ratio is 63 parts of Part B to 37 parts of Part A. This is not a one to one mixture. An accurate gram scale is required.

Polyurethane Resin

Odorless Casting Resin or Plastic Casting Resin. Not completely odorless but is called that anyway. Mix two equal parts of Part A and Part B and compound will form a solid plastic in a few minutes. Great for artists who want to reproduce their own "Resin Kits." Works great in a silicone mold. Color is sort of a amberish, translucent white. Can be painted, but don't use a silicone mold release.

*S* = Special Shipping Required.
