Details

Higher Density for Strength and Improved Detail

This 6 lb. density foam comes as a two-part kit, both parts equally mixed. It is a closed-cell system, meaning individual cells of foam trap in air and keep liquids out. Compared to lower density foams, the 6 lb. Mix and Pour Foam offers superior compressive strength (120 psi), so it's ideal filling cavities that will be used to support a heavy load. It is often used to make millwork, floats for wastewater treatment plants, and Coast Guard buoys. Because of its smaller cell structure, it is also frequently used to make detailed plugs or sculptures.

Features

  • 6 lb. foam expands approximately 10 times its liquid volume before cure, and will fill any shape.
  • Closed-cell structure does not react with oil or gasoline, and will not absorb water.
  • Laminate directly onto foam using epoxy or polyester resin.
  • Can be pigmented with urethane pigments (#141, #143).
  • Also compatible with latex paint, and in-mold parting wax (#1016).
  • This foam is designed to meet USCG Title 33, Chapter 1, Part 183 when mixed properly.

Mix Ratio

  • Mix Ratio: 1:1 by Volume

Tips

  • Once two parts are mixed, it will begin to react and expand within 60 seconds, and will continue for several minutes.
  • Before filling cavities for insulation, flotation or reinforcement, determine how much foam you'll need. First, calculate the volume of your container in cubic feet. For example 1 ft. high x 1 ft. long x 2 ft. deep = 2 total cubic feet. Second, for 6 lb. foam, multiply that total by 7.5. In this case, 2 cubic ft. x 7.5 = 15 lb. of required foam.
  • Utilize small pours to prevent expansion damage, waiting 15-20 minutes between each pour

Very prompt shipping and received the order in good shape. I have only used a small portion of the two-part foam but it seems to work great. I used it between the roof and the roof brace on my 1957 Chevy wagon and it is solid. Filled the space between the brace and roof without distorting the roof. Just be sure to have everything at 70 degrees F (per manufacture's recommendation) or it does not expand nearly as much.

Good product. I've used similar 2-component foams many times in the past and have lots to compare to. The 6-lb product I bought is excellent to use because of its higher density, its relatively slow cream time and the good homogenous bubble structure. We don't have a lot of applications, but when we do, we'll be back for more. Thank you for a good product and quick service!

Great product ... consistent foam expansion timing for easy application with fast curing into a dense foam
