Sylmasta Titanium Supergrade HT Epoxy Paste 4x500g
Sylmasta Titanium Supergrade HT is an alloy-reinforced epoxy paste (PHT) for metal, wood, and most plastics on pipelines, tanks, pumps, valves, and stress-bearing plant exposed to high heat. Tool it onto prepared surfaces so maintenance crews can rebuild worn sections, fill holes and cracks, and seal against corrosion and chemical attack.
- Seals pipelines, tanks, pumps, valves, and metal castings against corrosion and chemical attack in high-temperature service.
- Keeps worn shafts, damaged keyways, and large areas of pitting rebuilt with a machinable alloy-reinforced repair.
- Stays thixotropic with a light consistency and little sag for vertical and complex plant work.

Sylmasta Titanium Supergrade HT Epoxy Paste - 4x500g
Sylmasta Titanium Supergrade HT is an alloy-reinforced epoxy paste supplied as a 4 x 500g pack (PHT-4x500g) for hand-tool application on metal, wood, and most plastics. Maintenance crews use it on pipelines, tanks, pumps, valves, metal castings, worn shafts, and damaged keyways to rebuild heavy damage and seal against corrosion and chemical attack in high-temperature plant service.
Key Features
- Seals pipelines, tanks, pumps, valves, and metal castings against corrosion and chemical attack in aggressive plant environments.
- Keeps worn shafts, damaged keyways, and large areas of pitting rebuilt toward original wall thickness on stress-bearing equipment.
- Forms a smoother machinable finish than regular epoxy pastes thanks to corrosion-resistant platelet reinforcement.
- Rebuilds exterior pipe wall thickness and relines worn areas in pumps, valves, and associated equipment.
- Tool-applies with a light consistency and little sag, and is virtually odourless for indoor plant work.
- Stays thixotropic and easier to work than stiff traditional epoxy pastes on larger plant repairs.

Frequently Asked Questions
What high-temperature rebuild jobs is Sylmasta Titanium Supergrade HT built for?
Sylmasta Titanium Supergrade HT (PHT) is an alloy-reinforced epoxy paste that rebuilds worn and damaged surfaces and seals against corrosion and chemical attack on stress-bearing equipment in high-temperature service. Plant and maintenance teams tool it onto pipelines, tanks, pumps, valves, metal castings, worn shafts, and damaged keyways, fill holes and large cracks, repair pitting, and rebuild exterior wall thickness back toward original specification.
How is Sylmasta Titanium Supergrade HT mixed and tooled on?
Surfaces must be dry, grease-free, cleaned, and roughened for adhesion, with a defined 3-5 mm profile so the paste locks in. Mix 3 parts resin to 1 part hardener by weight or volume; whole kits ship Part A and Part B in the correct ratio. Mix with a trowel or hand tool until streak free and uniform. 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. Working time is 180 minutes; recoat after approximately 4-6 hours; functional cure in 16 hours; 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 Titanium Supergrade HT differ from Ceramic Supergrade or Industrial Metal paste?
Titanium Supergrade HT (PHT) is an alloy-reinforced paste aimed at high compressive strength and high-temperature service on stress-bearing metal plant, with corrosion-resistant platelets that machine to a smoother finish. Ceramic Supergrade (PCG) is a silicon carbide ceramic-filled paste for abrasion wear on silos, chutes, and similar plant. Industrial Metal (PST) is a separate metal-filled paste family with different mix and cure timing. This listing is Titanium Supergrade HT paste only; Ceramic Supergrade and Industrial Metal packs are listed separately on this storefront when you need those chemistries.
What hardness, strength, and service temperature does cured Sylmasta Titanium Supergrade HT reach?
Per the Titanium Supergrade HT TDS, Shore D hardness is 90 at full cure (24 hours). Typical strengths are tensile 35 MPa, compressive 130 MPa, flexural 100 MPa, and lap shear on steel 14 MPa. Continuous service is 80°C when room-temperature cured and 200°C when post-cured; intermittent post-cured service reaches 250°C with approximately 50% property reduction. For optimum high-temperature performance, follow a TDS post-cure schedule such as 2 hours at 20°C plus 3 hours at 150°C, or ramp to 150°C and hold for 3 hours.
What chemical and corrosion performance does Sylmasta Titanium Supergrade HT provide?
Corrosion-resistant platelets reinforce Titanium Supergrade HT so cured repairs protect pipes, tanks, machinery, and surfaces from corrosion and chemical attack in aggressive environments, and machine smoother than many regular epoxy pastes. TDS chemical immersion (120 days) rates many common acids, alkalis, solvents, and deionised water as Good or Excellent. Density is typically 1.6 g/cm3 with less than 1% shrinkage and 100% non-volatile content per the TDS.
What pack is available for Sylmasta Titanium Supergrade HT on this storefront, and how should it be stored?
This listing is PHT-4x500g: Titanium Supergrade HT in a 4 x 500g pack. Sister sizes (500g, 2kg, 5kg, 33.33kg) appear on the TDS but are not currently live here. Store out of direct sunlight in dry, frost-free conditions between 15°C and 20°C; under those conditions shelf life is three years from manufacture (minimum shelf life 24 months at 24°C per Technical Data).
