Micronized Rheology Modifier
CeraTHIX 68ST is a micronized rheology modifier developed for use in low polarity aliphatic and aromatic solvent-based coatings. It may also be used in powder coatings as a flow and leveling agent.
CeraTHIX 68ST must be subjected to solvent wetting, deagglomeration, and high-shear dispersion. Elevated temperatures based on the solvent content of the system are required to achieve full benefits.
Incorporation of higher polarity solvents will reduce the recommended incorporation temperature range. Heating above the range to activate the product can result in seeding which will appear as small, soft particles. Stirring must be maintained while cooling the coating below the recommended processing conditions to avoid a false body effect which presents in a higher apparent viscosity that is often lost when sheared. CeraTHIX 68ST may also be incorporated into powder coatings at the pre-mix stage to improve flow and leveling properties.
Recommended Temperature Range:
- Low-polarity systems with KB 25-65 (mineral spirits, naptha, isopar): 60-75°C
- Mid-polarity systems with KB 65-105 (aromatics like xylene or toluene): 40-55°C
Features and Benefits:
Builds viscosity and provides thixotropy
Provides sag control
Improves coating stability
Improves flow and leveling in powder coating
