Rheology modifiers for the control of sedimentation and sag resistance!
For rheology control, Arkema offers the formulator a wide range of products based on castor oil derivative and a variety of chemistries such as amide, urethane, oxidised polyethylene, to achieve the following performance properties:
- Sag control
- Anti-settling
- Low thickening at high shear
- Good levelling
- Recoatability
- Transparency
The products are supplied under various supply forms (powder, paste, liquid) to fit with the formulators' processing constraints.
Applications
These rheology modifiers are especially used in :
- Protective coatings and marine paints, as well as heavy-duty coatings and ACE (agricultural, construction and earth-moving coatings)
- General industry coatings
- Industrial wood finishes
- Automotive coatings
- Architectural coatings
- Can and coil coatings
- Adhesives and sealants
Surface modifiers
Based on polyethylene, polypropylene and PTFE, for the control of surface lubricity and appearance, these products are available as micronised powders or dispersions of micronised powder in water or organic solvents. These high performance products enable the formulator to control both the lubricity and appearance of coatings and to reach the following performance properties:
- Gloss and matt control
- Slip and scratch
- Mar, rub and abrasion
- Sanding aids
- Solvent resistance and water repellency
- Blocking resistance
- Texturing
- Stain resistance
Applications
The end application markets for these additives are mainly :
- Powder coatings
- Industrial coatings
- Can and coil coatings
- Industrial wood finishes
Flow and leveling
Flow and leveling agents for the enhancement of surface properties!
Crayvallac® additives are high performance flow and levelling agents for the control of coating surface properties. Based on polyester and acrylic chemistries, they have been developed to provide the following benefits :
- Eliminate film surface defects
- Improve substrate wetting
- Air release properties
- Defoaming properties
Application
The end application markets for these additives are mainly :
- General industrial coatings
- Can and coil coatings
- Industrial Wood Finishes
- Automotive coatings
