Adhetron Alum-Poxy Stainless Aluminum-Filled Epoxy Putty

Adhetron Alum-Poxy Stainless Aluminum-Filled Epoxy Putty 120 g is a two-component, kneadable epoxy putty designed for repair and reshaping applications on aluminum and metal parts. After curing, it forms a light metallic gray structure and, after a certain time, becomes suitable for processes such as cutting, drilling, sanding, and painting. Its solvent- and VOC-free formulation supports a more controlled application approach in maintenance and repair operations. The product stands out among epoxy-based repair putties classified as an industrial adhesive thanks to its aluminum-filled structure.

Alum-Poxy Epoxy Putty: Product Definition and Chemical Structure

Alum-Poxy is a two-component, aluminum-filled epoxy resin–based repair putty that is activated by hand kneading. Its primary purpose is to repair aluminum or aluminum-dominant metal components by filling cracks, holes, wear, and loss-of-form areas. Its non-rusting nature after cure can be a reason for preference, especially in repairs exposed to moisture and outdoor conditions. Manufacturer/origin information: Adhetron is a brand of Pulsar Kimya Sanayi ve Ticaret A.Ş. and has a Türkiye-based organization.

Alum-Poxy Technical Performance and Strength Properties

This epoxy putty allows application with a 5–7 minute working time after mixing and is described as reaching a functional cure level in approximately 60 minutes. A typical full cure time is given as 24 hours; once this period is completed, mechanical machinability on the part increases. The hardness is specified at Shore D 80, and its metallic gray color can provide visual compatibility with repaired aluminum surfaces. In terms of industrial adhesive performance, typical lap shear strength is stated as 4.2 MPa on steel and 3.5 MPa on aluminum.

Post-Cure Machinability and Chemical Resistance

The cured structure is described as becoming suitable for workshop operations such as sawing, drilling, carving, sanding, and painting after roughly 60 minutes. With compressive strength given as 55 MPa and shrinkage stated as below 1%, it can offer advantages in maintaining shape stability in filled areas. Continuous temperature resistance is specified as -40 °C to +120 °C, and short-term peak resistance as -40 °C to +150 °C, making it applicable where sudden temperature changes may occur. The chemical resistance information includes hydrocarbons, ketones, alcohols, esters, halocarbons, saltwater solutions, and diluted acids and bases; however, verification through on-site testing is recommended for specific process chemicals.

Surface Preparation, Application Steps, and Compatibility Notes

Before application, cleaning the surface from oil, dirt, loose oxide layers, and weak coating residues is considered critical for epoxy-based industrial adhesive performance. The required amount of material is cut, kneaded by hand until a uniform color is achieved, and then applied to the repair area within about 2 minutes after mixing. The material is pressed into cracks and voids, excess is scraped off, and the surface can be shaped using a moistened tool. Since adhesion may be limited on low surface energy plastics such as PP, PE, and PTFE, an adhesion test should be carried out on these substrates before application.

Sector-Based Uses and Key Advantages

The product is positioned across various industries for fast repair of aluminum-bodied equipment in maintenance/repair and production-support operations. In automotive and transportation, it can be used on radiator housings, aluminum connectors, and body components; in marine applications, on aluminum parts of boats; and in HVAC and plumbing, on pipes, fittings, and connection elements. In industrial manufacturing facilities, it can be evaluated for filling and reshaping needs on machine parts, tanks, castings, and molds. Being solvent/VOC-free, described as non-flammable, and offering post-cure machinability are among the main advantages that provide practical field use.
