The 'D' rating relates to the Moisture Resistance or Durability of the glue.
'Selleys Aquadhere Exterior PVA Glue':http://www.selleys.com.au/adhesives/construction/water-based-adhesive/aquadhere-exterior/ is a D3 Crosslinking PVA Glue
D3 generally describes Crosslinking Exterior grade PVA glues with good weather/water resistance (Not water proof). Cross Linked PVA's are much more water resistant than standard Interior grade PVA's and sometimes described as 'yellow glues'
