DWH grades are designed for static fits in machine assembly so they do not include low-friction fillers. DWH resins are produced in various viscosities and have more than 80% metallic fillers. DWH is used to mold static machine components in-place and to eliminate expensive machining and scraping. It can also be used as a repair material in maintenance. Common uses for the different grades are listed below. Its ability to mold to any shape makes it possible to shim with 100% contact.

DWH 310 FL - has steel fillers and is often used to produce bearing seats, align ball screws, align columns to beds, locate hardened seats in identical pallets, etc.

DWH 311 FL - has aluminum fillers with a lower specific weight therefore, is less expensive for a given volume. It is frequently used for filling key ways and bolt holes.

DWH 311 Putty - is a thin putty used in applications where the sealing and injection method is less practical; for instance, a segmented surface. A thickener powder is available for vertical or overhead applications.

• Thickener Powder is available for all DWH grades.

To Find the Grams of DWH Required:
Example: 5" wide x 48" long x .062" thick = 14.88cubic inches x 45 (DWH 310FL) = 670 grams of DWH needed.
Cubic inches to
be filled x
45 = DWH 310FL
31 = DWH 311 FL
32 = DWH 311 Putty
