The Polyester Resin Grey 300ml Styrene Free is a two-part, cartridge-dispensed chemical anchoring resin designed to secure threaded rods, rebar and bolts into drilled holes in concrete, brick and natural stone where a styrene-free formulation and reduced odour are required. Supplied in a 300ml dual cartridge for use with standard caulking guns and static mixer nozzles, this product cures to a grey, load-bearing polymer that bonds metallic fixings into structural substrates.

Formulation and technical details: the product is an unsaturated polyester anchoring resin, styrene-free and filled to give improved thixotropy for vertical and overhead holes. The cured finish is grey. The cartridge is compatible with 300ml dispensing tools and standard static mixer tips. It is intended for use with metric threaded rods and anchors to common DIN/ISO/BS sizes (typical application M8–M24); since head type and drive type are dependent on the fixing used, these are not applicable to the resin itself. Duchy Fasteners supplies full safety and handling documentation in line with CLP and REACH requirements and the product is manufactured under ISO 9001 quality management systems.

Typical applications include structural anchoring in new build and refurbishment, mechanical and electrical fixings, balustrades, safety barriers, façade anchors, heavy machinery baseplates and repair dowelling. It is widely used across construction, civil engineering, rail, utilities and renewable energy projects where trapped odour or VOC limits are a concern, and for retrofit applications in occupied buildings.

Key benefits of the styrene-free polyester resin are reduced odour and lower VOC emissions during application, good adhesion to concrete, brick and stone, and cured chemical resistance that helps protect embedded metalwork from corrosion. The material provides a robust load transfer when installed using drilled-hole anchor design guidance (refer to project design codes such as BS EN 1992/Eurocode 2 and relevant anchor design documents). It is compatible with common threaded bars including zinc-plated and stainless steel types when installed according to the technical datasheet.

Duchy Fasteners stocks the 300ml cartridge with matching static mixer nozzles and offers single cartridges and bulk pack options; dispensing guns and a range of compatible threaded rods and accessories are also available.
