What do the numbers and letters in a part name mean?
Great question! We get asked this a lot. Let’s take a look at WS8020RC B1/2.
WS = the sealant manufacturer, in this case Royal/HB Fuller
8020RC = the identifier chosen by Royal/HB Fuller. In this case, RC means rapid cure.
B = The class of sealant which indicates its consistency.
½ = The amount of time you have to apply the sealant. This number is measured in hours, so ½ would equate to 30 minutes.
