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.
