In the UK, the term ‘RAINPROOF’ was authorised for use on the label.

High and low rainfall events were simulated under laboratory conditions

Doff utilises unique Resin Technology to produce a pellet that has enhanced resistance to rainfall. Trials show that after 7 days under simulated heavy rainfall, it is the most resilient pellet.
