Matching conclusion
Both designed for radiation-cured systems with low thickening and gloss stability across coat weights. VS3550U validated for UV roller lines up to 15 m/min.
Vistamatt matches on the particle route and application rather than claiming an identical product. Qualify a replacement by screening VS3550U against your current SYLOID® RAD 2005 control at matched gloss, holding dispersion, film build and cure constant.
Evaluation positioning. Vistamatt VS3550U is designed for evaluation in applications currently using SYLOID® RAD 2005, 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 VS3550U a direct replacement for SYLOID® RAD 2005?
VS3550U is matched to SYLOID® RAD 2005 on particle route and application, not sold as an identical drop-in. Both are amorphous silica matting agents for UV wood & panel (roller). Qualify by screening VS3550U against your current SYLOID® RAD 2005 control at matched gloss.
How do the particle sizes compare?
SYLOID® RAD 2005 runs at a controlled PSD particle profile; VS3550U is 5.5-6.0 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® RAD 2005 is typically used at typ. 2-5% on total formulation. VS3550U 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® RAD 2005?
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.
