Protal^™ Liquid Epoxy Coatings Celebrate 40th Anniversary: 1986 – 2026

Winn & Coales International Ltd (WCI), leading manufacturer and supplier of corrosion prevention, waterproofing and sealing products, proudly commemorates the 40th anniversary of its Protal^™ range of liquid epoxy coatings. The trusted solution for pipeline protection, Protal^™ liquid coatings are high-build, fast-curing, 100% solids epoxies suitable for an array of above and below ground corrosion prevention applications.

At the time of the product line’s acquisition in 1986, Protal was already a highly regarded and well-established range of liquid coatings. To further strengthen WCI’s portfolio, the group of companies acquired ‘Protal Coatings’ to complement their renowned range of corrosion prevention tapes.

In line with the company’s mission to implement a continuous program of improvement and innovation, WCI’s North American subsidiary responded to market demand in the 1990’s with the development of Protal 7200^™—an advanced two-part liquid epoxy coating designed to complement factory-applied Fusion Bond Epoxy (FBE) coatings. To this day, Protal 7200 remains the signature product of the Protal series  and is a popular choice for owner groups and contractors worldwide conducting pipeline protection, maintenance and rehabilitation work.

In response to EU and UK REACH regulations, the eminent choice of Protal coating for domestic customers is the specially formulated Protal 7300^™ (UK). Offering excellent gouge, abrasion and impact resistance, this moisture tolerant pipeline coating was reformulated to comply with both EU and UK laws regarding the manufacture and supply of chemical substances, in addition to offering improved brushing characteristics for the user during application. The product is approved for use by the UK’s multinational utilities company and features in their National Grid Coatings Register in multiple product groups (9, 9c and 10).

As of 2026, Protal’s popularity continues to endure, establishing itself as the go-to solution for pipeline and critical infrastructure protection due to its ease of use, durability, and excellent substrate adhesion and coverage.

WCI Group Chair, Chris Winn, said, “As we commemorate forty years of Protal^™ liquid coatings, we celebrate a journey defined by innovation and resilience. This milestone underscores our unwavering commitment to advancing corrosion prevention technologies and providing solutions bearing a name that our customers know and trust. Looking ahead, our continued investment in research and development ensures we can respond to consumer demand and remain at the forefront of manufacturing sustainable solutions for an evolving commercial landscape.”
