Polyamide rheology additives CRAYVALLAC MT

Product Benefits

Polyamide rheology additives/CRAYVALLAC MT is a micronised amide modified hydrogenated castor oil rheology modifier for solvent-based and solvent-free coatings. Polyamide rheology additives/CRAYVALLAC MT is suited to coating systems based on aliphatic hydrocarbons, aromatic hydrocarbons and aromatic hydrocarbon/alcohol blends. Compared to the most basic hydrogenated castor oil based rheology modifiers, Polyamide rheology additives/CRAYVALLAC MT is more tolerant to stronger solvents. The result of this is a lowered risk of problems such as seeding and false-body. The following table gives processing temperature guidelines for some solvent systems commonly used in coatings:

Aliphatic hydrocarbons :35 - 75°C (95 - 167°F)

Aromatic hydrocarbons :30 - 50°C (86 - 122°F)

Aromatic hydrocarbon/ Alcohol blends: 30 - 50°C (86 - 122°F)

Solvent free epoxy coatings :40 - 60°C (104 - 140°F)

Storage and Handling

Follow procedures typically recommended for polymer dispersions. Use corrosion-resistant storage tanks and piping. Air-operated diaphragm pumps are preferred. Avoid temperature extremes. Do not freeze; store between 5°- 30°C. Under these conditions, the product may be stored for up to 4 years from production date.
