Catalysts
Dioctyltin Dilaurate (DOTL) | Manta CAT-DOTDL
Manta CAT-DOTDL is dioctyltin dilaurate (CAS 3648-18-8), an organotin additive used as a catalyst in RTV silicone and polyurethane systems and as a stabilizer and lubricant in flexible PVC and a lubricant in rigid transparent PVC, offering lubrication, clarity and resistance to sulfur staining. It is used as an option where dibutyltin compounds are restricted.

Overview
Manta CAT-DOTDL is a dioctyltin dilaurate additive that provides lubrication, weather resistance and high transparency. In PVC processing it offers self-lubricating properties and resists sulfur staining. In silicone and polyurethane systems it acts as a catalyst for applications where dibutyltin grades such as Manta CAT-DBTDL are restricted.
Moving to a dioctyltin grade does not remove the regulatory review. Dioctyltin dilaurate is on the REACH Candidate List of substances of very high concern, and Annex XVII entry 20 restricts dioctyltin compounds in certain articles supplied to or used by the general public. Check the rules for your market and end use, and refer to the Safety Data Sheet.
Key Features
- Internal and external lubrication that reduces friction during polymer processing
- Resistance to sulfur staining for long-term color stability
- High transparency in flexible and rigid PVC
- Works in combination with mercaptide tins or Ba/Zn stabilizers

Frequently Asked Questions
When should I choose Manta CAT-DOTDL instead of Manta CAT-DBTDL?
CAT-DOTDL is used where dibutyltin compounds such as CAT-DBTDL are restricted. Its tin content is 15.0-16.0%, against 18.0%-19.2% for CAT-DBTDL, so the dosage may need adjusting. Dioctyltin compounds have their own restrictions, so check the rules for your end use.
What is the regulatory status of Manta CAT-DOTDL in the EU?
Dioctyltin dilaurate has been on the REACH Candidate List of substances of very high concern since January 2021, as toxic for reproduction. Annex XVII entry 20 also restricts dioctyltin compounds in certain articles supplied to or used by the general public. Contact us for the SDS and your specific case.
How does Manta CAT-DOTDL perform in PVC?
It works as a stabilizer and lubricant in flexible PVC films, sheets and hoses and as a lubricant in rigid transparent containers. It keeps clarity, resists sulfur staining and can be combined with mercaptide tins or Ba/Zn stabilizers.
