Based on a European directive to ensure the health and safety of individuals and control damage to the environment, the RoHS specification basically permits extremely low levels (<ppm) of six noxious entities in adhesive formulations. They are:
- Lead and lead based materials
- Hexavalent chromium
- Polybrominated biphenyl (PBBs)
- Polybrominated diphenyl ethers (PBDE) materials
All Master Bond materials are RoHS compliant and do not contain any of the entities listed above.
