Type:
Look for SIS grades tailored for coatings or adhesives, as these are more likely to work well in paint formulations.
Size and Form:
Molecular Weight: A lower molecular weight SIS may enhance flow properties, while a higher one can increase the film's mechanical strength.
Particle Size: If using SIS in a solid or powder form, ensure the size allows for proper dispersion.
Packaging:
Ensure the packaging protects the SIS from moisture and environmental degradation. Air-tight, UV-protected containers are ideal if SIS is prone to oxidative damage.
Environmental Stability:
Check for UV and oxidation resistance, especially if your paint will be used outdoors or under varying environmental conditions.
