Description
The Soudal T-Rex Power Turbo is a high-quality, neutral-cure, elastic adhesive-sealant manufactured by Soudal, the world’s largest independent sealant and adhesive manufacturer. Based on SMX hybrid polymer technology (silyl-modified polymer), it delivers an exceptionally fast strength build-up with a skin formation time of just 5 minutes and a curing speed of 2 to 3 mm per 24 hours. It is KOMO-certified as a construction adhesive under BRL 3107.
Unlike traditional polyurethane or silicone adhesives, the SMX polymer base gives T-Rex Power Turbo a unique combination of very high final bond strength (3.80 N/mm² tensile), permanent elasticity (200% elongation at break) and excellent adhesion to damp surfaces. It is isocyanate-free, virtually odourless, paintable with water-based paints, and compliant with LEED low-emitting materials requirements (SCAQMD Rule 1168).

Where to Use
- Elastic bonding of panels, profiles, skirting boards and decorative elements
- Mounting mirrors, shelving brackets and fixtures to walls
- Bonding in the building and metal industry (steel, galvanised steel, aluminium alloys)
- Fixing cladding, signage and facade elements
- Sealing and bonding in construction, renovation and fit-out projects
- Bonding to damp or slightly wet substrates where other adhesives fail
Compatible Substrates
T-Rex Power Turbo bonds to most common building substrates including treated wood, concrete, brick, natural stone (bonding only, not as joint sealant), aluminium, steel, galvanised steel and a wide range of plastics.
Tested metals: steel, AlMgSi1, electrolytic galvanised steel, AlCuMg1, flame galvanised steel, AlMg3 and steel ST1403.
Tested plastics: polystyrene, polycarbonate (Makrolon), PVC, ABS, polyamide, PMMA, fibreglass-reinforced epoxy and polyester.
Not suitable for: PE, PP, PTFE (Teflon) and bituminous substrates. Not recommended for stress-loaded bonding of PMMA or polycarbonate (risk of stress cracking).
How to Apply
- Surface preparation: Ensure substrates are rigid, clean, dry or slightly moist, and free of dust and grease. For porous surfaces in water-loaded applications, prime with Soudal Primer 150. For non-porous surfaces, use Soudal Surface Activator.
- Apply adhesive Using a caulking gun, apply in uniform strips or dots (every 15 cm) on one substrate. Always place an adhesive strip or dot on corners and panel edges. Do not apply in a closed perimeter: leave gaps to allow moisture to reach the adhesive for curing.
- Bond: Press the second substrate firmly into position and tamp with a rubber hammer. The adhesive is adjustable for approximately 5 minutes.
- Support, If required, support the bonded materials while curing. On absorbent substrates with a thin adhesive layer, the bond is hand-tight after approximately 20 minutes and loadable after about 3 hours.
- Finishing: Smooth exposed beads with a soapy solution or Soudal Finishing Solution before the 5-minute skin time elapses.
- Clean-up: Remove uncured adhesive immediately with Soudal Fix ALL Cleaner. Cured material can only be removed mechanically.
Chemical Resistance
Good resistance to: salt water, fresh water, aliphatic solvents, hydrocarbons, ketones, esters, alcohols, diluted mineral acids and alkalis.
Poor resistance to: aromatic solvents, concentrated acids and chlorinated hydrocarbons.
Important Notes
- Not suitable for continuous water immersion, sanitary applications or aquarium bonding.
- Cannot be used as a glazing sealant.
- On natural stone, T-Rex Power Turbo may only be used as a bonding adhesive on the underside of tiles: not as a joint sealant on the visible face.
- Avoid contact with bitumen, tar, EPDM, neoprene and butyl: plasticiser migration can cause discolouration and adhesion loss.
- Paintable with most water-based paints, but always conduct a compatibility test. Alkyd resin paints may take longer to dry over the cured adhesive.
- The product may discolour under extreme UV or high-temperature conditions; this does not affect mechanical performance.
- Thicker adhesive layers and non-absorbent substrates will extend curing time beyond the standard rates.
