Amide wax based rheology modifiers with thixotropic behaviour
Why use Iscathix SR?Iscathix® SR is a 100% active, organic amide based rheological additive, suitable for use in a wide range of coatings. Unlike hydrogenated castor oil based products, Iscathix SR is very tolerant to strong solvents and high process temperatures.
Product benefits
- Very resistant to seeding and false body effects
- Excellent sag resistance / pigment suspension properties
- Improved brushability
- Minimal gloss reduction
- Improves storage stability, even at elevated temperatures
- Ease of incorporation
ApplicationsIscathix® SR can be used to impart thixotropic behaviour into a wide range of systems, including: general industrial coatings, 2K epoxy primers and top-coats, 2K polyurethanes, chlorinated rubbers, thermoplastic acrylics, 2K isocyanate-free acrylics, road marking paints, high solids systems, floor paints, adhesives, sealants, etc.

Incorporation
Iscathix® SR should be incorporated during the pigment dispersion stage of coating manufacture – ideally, using high speed dispersing equipment. When appropriate temperature and shear conditions are obtained, a dwell time of 20 - 30 minutes should be observed. The activation temperature for Iscathix SR will depend on which solvents are being used, but should be within the range 40-65 °C.
Use level Recommended level of addition: 0.5 – 2.0%, calculated on total formulation.
