  • 2-methylimidazole
  • 1-vinylimidazole

BOMcheck has automatically updated your RCDs for these three new substances.

The following REACH Candidate List substance can be found in concentrations > 0.1% w/w in materials and parts in supplied articles:

SubstanceLikely to be found in supplied articles?
Dibutylbis(pentane-2,4-dionato-O,O')tin [CAS: 22673-19-4]Yes - substance has similar properties to Dibutyltin dichloride (DBTC) and can be added to PVC plastic to make it more stable to heating and to protect against degradation from sunlight. DBTP can also be used as a catalyst for the production of plastics including polyurethanes and certain silicones, and for room temperature vulcanisation (RTV) silicone rubber systems.

Updating Declarations

IF YOU HAVE CREATED FULL MATERIALS DECLARATIONS (FMDs) ON BOMcheck THEN YOU WILL NOT NEED TO TAKE ANY ACTION. RCDs which are generated from your FMDs have been updated automatically for these new substances. The Approval Date for these RCDs has been set to 25 June 2020. The Approval Date for your FMDs remains the same.
