AMSTERDAM (Reuters) - Akzo Nobel AKZO.AS CEO Ton Buechner repeated on Monday his opposition to a March 20 takeover proposal from U.S. rival PPG Industries PPG.N, saying he sees no merit in negotiating with PPG.

Buechner and Akzo Chairman Antony Burgmans have been under pressure from major shareholders, many of whom say the company should enter talks on PPG’s 24.5 billion euro ($26.1 billion) offer.

“It did not address the key stakeholder issues and other issues like uncertainties and risks that we had already raised in response to their first proposal” on March 9, Buechner said.

He cited antitrust and other concerns, adding that it was not “our duty” to advise PPG on how to make a deal successful when Akzo is not the one asking for it.

Buechner is due to detail his plans to instead spin off Akzo’s chemical division on April 19, despite scepticism from investors and analysts that the plan could rival PPG’s cash and share offer, which is worth 90.20 euros per share at current prices.

Akzo shares were trading up 0.3 percent at 77.96 euros Monday.
