Matching conclusion
Both fine-particle silicas for thin-film and leather coatings where surface smoothness and film clarity matter. VS131A matched on the fine route for leather and synthetic leather, screened on dark substrates.
Vistamatt matches on the particle route and application rather than claiming an identical product. Qualify a replacement by screening VS131A against your current SYLOID® C 803 control at matched gloss, holding dispersion, film build and cure constant.
Evaluation positioning. Vistamatt VS131A is designed for evaluation in applications currently using SYLOID® C 803, and offers comparable performance in the application described above when qualified at matched gloss. Published figures indicate a similar performance range based on internal testing; they are not a guarantee of equivalence in your formulation.

Frequently asked questions
Is VS131A a direct replacement for SYLOID® C 803?
VS131A is matched to SYLOID® C 803 on particle route and application, not sold as an identical drop-in. Both are amorphous silica matting agents for leather & synthetic leather finishes. Qualify by screening VS131A against your current SYLOID® C 803 control at matched gloss.
How do the particle sizes compare?
SYLOID® C 803 runs at a fine particle profile; VS131A is 3.2-3.5 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?
SYLOID® C 803 is typically used at typ. 1-5% on total formulation. VS131A starts at 2-4% for most systems. Confirm by screening at matched gloss, not matched loading.
Can I get a sample to test against SYLOID® C 803?
Yes. Vistamatt provides free 200-500 g samples (freight prepaid by Vistamatt), shipped with a screening plan matched to your system. Send your resin system, target gloss, application method and film build.
