What Siroflex does

Siroflex Limited is a UK-based manufacturer and supplier of silicones, sealants, adhesives, and polyurethane foams serving the construction, trade, and DIY retail markets. Founded in 1994 and headquartered in Dodworth Business Park, Barnsley, the company sells through two product architectures: its proprietary SX Trade Strength own-brand range and a private label/OEM offering that produces custom-branded products for retailers and distributors. Distribution is concentrated in the UK, with the company stating its products are stocked across the majority of National Merchants, Independents, and all National Trade Decorating Branches, alongside an OB1 product range. Siroflex is a wholly-owned subsidiary of France-based Arkema Group, operating within the group's Bostik adhesive solutions division, which provides access to 148 production facilities across 55 countries and a worldwide distribution network.

The business model is hybrid B2B/B2C: revenue is generated through trade and customised orders on a quote basis and through retail shelf sales to DIY consumers. Pricing is not publicly disclosed, and no contract-level economics are available. In 2024 Siroflex launched the Siroflex Academy, a training-led offering that delivers technical courses, customised sessions, and interactive events to customers and aspiring tradespeople via construction colleges, signalling an intent to deepen account relationships and build a trade-community moat. Marketing is multi-channel — a primary brand website, LinkedIn, Instagram, Facebook, a Linktree hub, and a technical knowledge base covering sealant-paint tolerance, surface pre-treatment, joint dimensions, and mirror bonding — but there is no disclosed use of AI/ML, software products, or proprietary technology platforms beyond the chemical formulations themselves. No revenue figures, headcount trends, or capital structure details are publicly available.

Broad incumbents

• 3M: Global diversified manufacturer with a sizable adhesives and sealants division serving construction, industrial, and DIY markets. Competes with Siroflex in sealants and construction adhesives through broader distribution and stronger brand recognition among professional trades.
• Dow Inc. Global materials science major producing silicone sealants, construction chemicals, and polyurethane systems. As a raw material supplier and finished-product competitor, Dow overlaps with Siroflex both upstream (silicon chemistry) and downstream (sealants/foams) in the construction value chain.
• Bostik: Bostik is Arkema's dedicated Adhesive Solutions division and the direct parent of Siroflex. It offers the broadest portfolio of sealants, adhesives, and foams globally, including the Siroflex SX Trade Strength line, and serves the same construction, trade, and DIY channels.
• Henkel AG: German multinational whose Adhesive Technologies division supplies sealants, construction adhesives, and DIY brands (e.g., Pattex, Unibond) through the same trade and retail channels Siroflex serves, making it a direct competitive counterpart at global scale.

Direct peers

• Sika AG: Swiss global specialty chemicals company with a major sealants, adhesives, and waterproofing business serving construction and trade channels. Sika competes head-to-head with Siroflex across silicones, construction sealants, and bonding products in UK and European markets.
• Soudal: Belgian family-owned manufacturer and one of the world's largest independent producers of sealants, PU-foams, and adhesives for construction, trade, and DIY. Directly comparable to Siroflex in product mix and channel strategy, with strong UK and European presence.
• Den Braven: European sealant and foam manufacturer acquired by Bostik/Arkema; many of Siroflex's own knowledge base technical documents reference Den Braven heritage content. Operates as a sister brand within the same Arkema/Bostik family with overlapping product range and channel reach.
• Everbuild Building Products: UK-based manufacturer of sealants, adhesives, foams, and building chemicals, owned by Sika. One of the closest direct competitors to Siroflex in the UK trade and DIY merchant channel, with overlapping product ranges and customer base.
• Tremco CPG UK: Specialty construction chemicals manufacturer supplying sealants, waterproofing, and building envelope products through UK trade merchants and decorators — a direct channel and product overlap with Siroflex's national merchant and trade decorating distribution.

Regional players

• H.B. Fuller: US-headquartered global adhesives manufacturer with growing construction and packaging adhesive offerings. While primarily North American, it competes in EMEA sealants/adhesives and represents the same commoditized specialty chemicals category as Siroflex.
