Product Information

Rhino Guard treated substrates are the first cellulose-based materials to incorporate a patented anti-microbial/anti-fungal treatment without sacrificing performance of the sheet. Effective against a broad spectrum of bacteria and fungi/mold, Rhino Guard materials have been used in the most challenging wet environments with trusted and proven performance since 2008.

Rhino Guard treated materials have recently been assessed under UL’s Claim Verification Program to resist 99.99% of black mold growth for up to 3- months, proving what many industry leaders already know.

Marketing Claim Verified by UL

Rhino Guard treated material inhibits 99.9% of black mold growth for up to 3 months

Verification Method

The organism used during fungal inoculation is Aspergillus niger, which is commonly referred to as “black mold”. The assessment is performed per ASTM G21 – 15, Standard Practice for Determining Resistance of Synthetic Polymeric Materials to Fungi, with the following modifications: - Each sample is tested in quintuplicates with the spore suspension referenced above. - The fungus is directly pipetted on to the material, instead of sprayed, as called out in the standard. - The inoculated test specimens are incubated for 90 days, instead of the 28 days called out in the standard. The following calculations are made for fungal reduction: Percent Reduction = (CC - TC)/CC x 100 Log Reduction = log CC - log TC or alternatively log (CC/TC) Where: CC = Untreated Positive Control Sample viable organism count after test (use results of the control sample with the lowest count). TC = Treated Test Sample viable organism count after cycle (use results of the test sample with highest count).

What is UL Verification?

UL Verification is an objective, science-based assessment that confirms the accuracy of marketing claims. Our independent assessment process scrutinizes the validity of specific advertising or promotional statements, giving you a way to separate verified fact from fiction.
