Matching conclusion
Both medium-particle wax-treated silicas for general and PU coatings with high matting efficiency. Vista-361C matched at the ~6.3 µm route for industrial and deep-matte systems.
Vistamatt matches on the particle route and application rather than claiming an identical product. Qualify a replacement by screening Vista-361C against your current ACEMATT® OK 500 control at matched gloss, holding dispersion, film build and cure constant.
Frequently asked questions
Is Vista-361C a direct replacement for ACEMATT® OK 500?
Vista-361C is matched to ACEMATT® OK 500 on particle route and application, not sold as an identical drop-in. Both are amorphous silica matting agents for industrial & deep-matte coatings. Qualify by screening Vista-361C in your own formulation against your current ACEMATT® OK 500 control at matched gloss.
How do the particle sizes compare?
ACEMATT® OK 500 runs around ~6.3 µm; Vista-361C is 6.2-6.5 µm (D50). Matching on particle route is the starting point; final selection depends on target gloss, film build and system.
What dosage should I start with?
ACEMATT® OK 500 is typically used at 1.5-7% on total formulation. Vista-361C starts at 2-4% for most systems. Confirm by screening at matched gloss, not matched loading.
Can I get a sample to test against ACEMATT® OK 500?
Yes. Vistamatt provides free 200-500 g samples (freight collect), shipped with a screening plan matched to your system. Send your resin system, target gloss, application method and film build.
