What Fourthane does

Fourthane is a Chilean-headquartered specialty chemicals company founded in 1996 by Cecil Fourt that develops and applies polymer-based repair and protective coatings for the global mining industry. Its core technology comprises proprietary Chilean-patent polymer formulations (epoxy compounds, polyurea coatings, rubber linings, and ceramic-reinforced polymers) organized into eight color-coded product lines — Red Line, Black Line (including anti-acid variants), Silver Line, Brown Line, Grey Line, Hex Line, Steel Line, and Silver Pulley — each engineered for specific failure modes such as abrasion, impact, cavitation, chemical attack, and precision metal repair in concentrator plants and conveyor systems. Fourthane also operates Splice Systems, a USA-based wholly-owned sub-brand producing conveyor belt splicing materials with in-house R&D.

The company sells directly to enterprise mining operators through a field-sales and on-site service model, with regional offices in Chile, the United States, Peru, Australia, Spain, and Brazil, and active distribution in more than 50 countries. Revenue is generated through two streams: one-time product sales of proprietary polymer compounds and recurring maintenance services delivered under multi-year permanent contracts covering coatings application (rubber linings for SAG/ball mills, polymer coatings, polyurea pond liners) and conveyor/pulley/screen mechanical maintenance. Pricing is quote-based and not publicly disclosed. The customer base is concentrated in a single vertical (mining concentrator plants), and the firm holds ISO 9001, ISO 14001, and ISO 45001 certifications, plus Avonni (2012) and Pro-Chile (2013) innovation awards.

Core offering

Fourthane manufactures and sells proprietary polymer-based repair and protective coatings — including epoxy compounds, polyurethane, polyurea, ceramic-reinforced polymers, and liquid steel composites — for the maintenance of conveyor belts, SAG/ball mills, flotation cells, pulleys, chutes, pumps, and other mining equipment. The company complements its product sales with on-site maintenance services (inspections, splicing, coatings application, relining, pulley and screen maintenance) delivered under permanent service contracts to mining customers worldwide.

Product overview

Fourthane offers a portfolio of polymer-based industrial coating and repair products for the mining industry, organized in color-coded product lines (Grey, Silver, Red, Brown, Black, Hex). The core offerings include: (1) Belt repair products (Red Line Classic, Red Line LB) for conveyor belt repairs; (2) Pulley lining repair products (Silver Pulley, Grey Line) for pulley covering repairs; (3) Abrasion and impact resistant coatings (Silver Line, Hex Line, Black Line series) for mill components, chutes, and flotation cells; (4) Cavitation resistant products (Brown Line) for pump impellers and flotation cells; (5) Liquid steel products (Steel Line) for precision metal repairs; and (6) Anti-acid coatings (Black Line 5511) for solvent extraction plants. All products are polymer-based formulations (epoxy, polyurethane, polyurea) designed for field application in mining concentrator plants. The company also provides Splice Systems (USA-manufactured splicing materials) as a sub-brand. Services include coatings application (rubber linings for SAG/ball mills, polymer coatings, polyurea pond liners), conveyor maintenance (inspections, splicing, repairs), pulley maintenance, screen maintenance, feeder maintenance, and mechanical component maintenance with specialized kits.
