Matching conclusion
Both fine, high-efficiency matting agents at a ~5 µm route. VS660 matched for waterborne clear wood with strong transparency on dark substrates.
Vistamatt matches on the particle route and application rather than claiming an identical product. Qualify a replacement by screening VS660 against your current grade 3600 control at matched gloss, holding dispersion, film build and cure constant.
Evaluation positioning. Vistamatt VS660 is designed for evaluation in applications currently using grade 3600, 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 VS660 a direct replacement for grade 3600?
VS660 is matched to grade 3600 on particle route and application, not sold as an identical drop-in. Both are amorphous silica matting agents for waterborne clear wood. Qualify by screening VS660 in your own formulation against your current grade 3600 control at matched gloss.
How do the particle sizes compare?
Grade 3600 runs around ~5.0 µm; VS660 is 5.0-5.3 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?
Grade 3600 is typically used at 1.5-4.5% on total formulation. VS660 starts at 2-4% for most systems. Confirm by screening at matched gloss, not matched loading.
Can I get a sample to test against grade 3600?
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.
