Synthomer plc is a British speciality chemicals company headquartered in London, supplying high-performance water-based polymers and ingredients to business customers across coatings, construction, adhesives, and healthcare end markets.[1] The company was formerly known as Yule Catto & Co. plc and changed its name to Synthomer plc in 2012.[2]

Design and History

The Synthomer identity is built around a distinctive blue that the company treats as a signature brand element. A workplace design project for Synthomer’s London headquarters describes incorporating the company’s “signature blue” throughout the space, and notes that the design team mimicked the logo with the repetition of column bases painted in the brand’s blue.[3] This confirms that blue is a central, recognised colour of the corporate identity, though no official colour specification has been published in the available sources.

The current corporate name dates to 2012, when Yule Catto & Co plc announced its intention to change its name to Synthomer plc. In its interim management statement, the board explained: “The Group trades under the name Synthomer across the majority of its business, and the Board has therefore decided that now is an appropriate time to reflect this in the Group’s name.”[4] Shareholders approved the change at an Extraordinary General Meeting, and the new name became effective on the London Stock Exchange with the ticker SYNT.[5]

The name change reflected a broader transformation of the business. According to the company’s 2012 trading statement, over the previous five years the group had been transformed “from a small, diversified chemical business, of which Yule Catto was the holding company, to a much larger, focussed speciality polymer business.”[6] The Synthomer name was already in use across most of the group’s operations, making the corporate rebrand a formal alignment with the existing trading identity rather than the introduction of a new brand.

Meaning and Symbolism

The company’s own communications do not provide an official explanation of the logo’s abstract form or its colours. The strongest available evidence concerns the brand’s blue, which is consistently described as “signature” in a design context, indicating that it functions as a recognisable brand colour rather than carrying a stated symbolic meaning.[3]

Typography and Design

The logo is available in full-size and icon formats for both light and dark backgrounds, indicating that the identity was designed with flexible applications in mind.[2]
