- Seals pumps, valves, metal castings, low-pressure pipes, and tanks against corrosion and chemical attack.
- Keeps holes, cracks, and pitting rebuilt with a machinable metal-platelet repair.
- Stays thixotropic with a light consistency and little sag for vertical and complex plant work.

Key Features
- Seals pumps, valves, metal castings, low-pressure pipes, and tanks against corrosion and chemical attack.
- Keeps holes, cracks, and pitting in pipes and tanks filled, and relines worn areas in pumps and valves.
- Forms a smoother machinable finish than regular epoxy pastes thanks to corrosion-resistant metal platelets.
- Rebuilds worn equipment and restores surface profile on industrial metalwork in aggressive plant environments.
- Works on wet surfaces and underwater for moisture-tolerant maintenance where dry-out is limited.
- Tool-applies with a light consistency and little sag, and is virtually odourless for indoor plant work.

Frequently Asked Questions
What repair jobs is Sylmasta Industrial Metal built for?
Sylmasta Industrial Metal (PST) is a metal-filled epoxy paste that rebuilds worn and damaged surfaces and seals against corrosion and chemical attack. Plant and maintenance teams tool it onto pumps, valves, metal castings, low-pressure pipes, tanks, and automotive bodywork, fill holes, cracks, and pitting, reline worn areas in pumps and valves, and restore surface profile on industrial metalwork. It is moisture tolerant and can cure on wet surfaces and underwater.
How is Sylmasta Industrial Metal mixed and tooled on?
Surfaces must be dry and free from grease, cleaned, and roughened for adhesion, with a defined 3-5 mm profile so the paste locks in. Mix 2 parts resin to 1 part hardener by weight or volume; whole kits ship Part A and Part B in the correct ratio. Mix until streak free and uniform, then spread with a putty knife, pressing firmly for full contact and to avoid trapped air. Bridge large gaps with fibreglass, sheet metal, or wire mesh. Gel time is 60 minutes; full cure in 24 hours. Apply between 13°C and 52°C. Wear eye protection and rubber or plastic coated gloves, and follow the Safety Data Sheet.
How does Sylmasta Industrial Metal differ from Industrial Metal Rapid 5 Minute?
Industrial Metal (PST) is the longer-working metal-filled paste with a 60-minute gel time, mix ratio 2:1, and moisture-tolerant wet-surface and underwater cure. Industrial Metal Rapid 5 Minute (PSF) is the fast sister paste with a 5-minute gel time, mix ratio 1:1, and functional cure in 60 minutes; Sylmasta published product copy states Rapid does not cure underwater or on wet surfaces. This listing is PST-4x500g only; the live Rapid sister pack is linked above when you need the fast paste.
What hardness, strength, and service temperature does cured Sylmasta Industrial Metal reach?
Per the Industrial Metal TDS, Shore D hardness is 85 at full cure (24 hours). Typical strengths are tensile 28 MPa, compressive 82 MPa, flexural 38 MPa, and lap shear on steel 18 MPa. Heat distortion is 56°C when cured at room temperature and 100°C when post-cured. Maximum service temperature is 130°C; to reach maximum heat resistance, cure 24 hours at room temperature, then heat at 80°C for 2 hours and 130°C for 3 hours before cooling, per the TDS post-cure schedule.
Is Sylmasta Industrial Metal suitable for drinking-water pipe repairs?
The Industrial Metal TDS states the paste is tested to BS 6920:2000 as suitable for use on drinking water (Thames Water Utilities Ltd, The Water Quality Centre). Sylmasta published product copy notes that when used with a SylWrap HD Pipe Repair Bandage, the repair system is suitable for pipes carrying drinking water. Always confirm local water-regulation requirements for your site before specifying.
