3M™ Fused Silica Advanced Shell System WDS3

3M™ Fused Silica Advanced Shell System WDS3 is a dry blend of fused silica and high performance additives that are used for investment casting backup slurries.

3M™ Fused Silica Advanced Shell Systems WDS 3 (Wide Distribution Slurry) is a patented dry blend of fused silica and high performance additives that are used for investment casting backup slurries. Featuring increased shell build and improved permeability, WDS3 helps to remove dips and minimize autoclave shell cracking.

• Shell build provides uniform coverage of corners and edges while still addressing the flow needed to fill slots and holes in difficult investment castings
• Unique slurry rheology substantially shortens drain times and increases foundry output
• Non-fiber based shell system is optimized for parts with difficult geometries and detail
• Improved knockout simplifies shell removal
• Unique slurry rheology substantially shortens drain times to increase foundry output
• Improved load carrying ability to reduce handling damage and cracking
