Benathix

Rheological additive for unsaturated polyester laminating resins

BENATHIX rheological additive is an extremely efficient, organically modified smectite clay developed to impart thixotropy and drainage control to unsaturated polyester laminating resins and gel coats. Unlike conventional organoclays or fumed silica thixotropes, BENATHIX rheological additive does not require high-shear mixing equipment. BENATHIX rheological additive is mixed into styrene, after which the resin and other ingredients are added.

Applications: Benathix rheological additive is a specially designed thickener for unsaturated polyester resins in structural applications.

Key Properties:

• Is a cost-effective alternative to fumed silica and other organophilic clays
• Is easy to disperse
• Allows rapid incorporation into styrene with low-shear mixers
• Provides consistent, stable viscosity and thixotropic index
• Imparts excellent drainage control, even at low viscosity and thixotropic indices
• Offers fast viscosity recovery rate after spray-out or roll-out
• Improved resistance to settling and syneresis
• Products better glass-wetting properties
• Is easier to handle than fumed silica
• Allows increased filler loadings
• Offers good clarity in cured resins
• Gives minimal gel-time drift
