RHEOBYK R 606 is a liquid rheology additive for solvent-borne and solvent-free adhesives and sealants based on polyurethane, epoxy, and acrylate resins. It is designed for use with pyrogenic silica or organophilic phyllosilicates and acts as a rheology modifier. This highly thixotropic product is suitable for solventborne and solvent-free (100% solids) adhesives and sealants.

Special Features and Benefits
RHEOBYK-R 606 is a thixotropic-reinforcing additive for polyurethane, epoxy, and acrylate resins that are rendered thixotropic with pyrogenic silica or organophilic phyllosilicates (organoclays). It reinforces the hydrogen bonds of the silica and phyllosilicates, resulting in increased thixotropy. For this reason, it achieves sufficiently high anti-sagging properties, with improved leveling and air release properties even with low quantities of silica or phyllosilicates.

Recommended Levels
5-15% additive (as supplied) based upon the pyrogenic silica or organophilic phyllosilicates (organoclays).
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.

Incorporation and Processing Instructions
The additive should be added to the resin before incorporating the silica/phyllosilicates whilst stirring. Post-addition is also possible.
