Who owns Siam Synthetic Latex Company Limited
One company in the researched set discloses a stake in Siam Synthetic Latex Company Limited, none of it sized by anyone who discloses it. Siam Synthetic Latex Company Limited is private, so no 13F reports it: a 13F covers exchange listed positions only. These figures exist because each holder disclosed the stake in its own filings.

Siam Synthetic Latex produces styrene butadiene latex in Thailand, running the plant that started up in 1993 at the Map Ta Phut Industrial Estate in Rayong. It is one of the four operating companies of the SCGC-Dow Group, the 50/50 joint venture formed in 1987 between The Dow Chemical Company and The Siam Cement Public Company Limited, where Dow provides the emulsion polymer technology and operating know how and Siam Cement's chemicals business provides the surrounding Thai petrochemical complex. The plant draws styrene from the group's adjacent styrene monomer and ethylbenzene unit and butadiene piped in from a local producer within the Map Ta Phut complex, and sells latex under the DOW LATEX name into coated paper and paperboard, carpet backing adhesives, concrete modification and binders for architectural paint.

Siam Synthetic Latex Company Limited files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Styrene-Butadiene Latex, Dow Thailand, About Us, Dow Family Thailand, Dow Inc. 2025 Form 10-K, Exhibit 21 Subsidiaries and SCG-Dow Group announcement (PlasticsNet). The ownership figures below come from the holders' filings instead, and are sourced row by row.
The disclosed stakes
One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.
Where each figure comes from
A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
- Dow Inc.. Thai equity-method joint venture (SCGC-Dow Group) manufacturing latex and specialty elastomers. Percentage taken directly from the 10-K table, which states 50.00 percent; written here as 50.0, not 0.5. No individual carrying value is disclosed: covered by the same combined balance described on the EQUATE row, so value_usd stays null. source
What this page is not
It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Siam Synthetic Latex Company Limited where a holder stated one, and are missing where no holder did.
