Use Selsil Ultra Clear for: High-clarity sealing of glass and metal joints, mirror installations, splashback edges, facade trims, and wet area fixtures.

Selsil Ultra Clear: A Technical Overview

Selsil Ultra Clear is a next-generation hybrid sealant designed for precision sealing where visual clarity and long-term performance are critical. Formulated with silane-terminated polymer technology, it combines the elasticity of silicone with the strength of polyurethane — without the hazards of isocyanates or solvents. This professional-grade sealant cures bubble-free, adheres strongly to glass, aluminium, timber, and ceramics, and is perfectly suited to indoor and outdoor applications. With a 300% elongation rate and 1.9 MPa tensile strength, it provides flexibility in moving joints and lasting durability across Australia’s demanding climates.

Core Features & Specifications

  • Crystal-clear finish ideal for glass, mirror, and ceramic joints
  • Silane-terminated polymer base – solvent and isocyanate free
  • 300% elongation and 1.9 MPa tensile strength for dynamic joints
  • UV and chemical resistant – long-term durability in exposed areas
  • Non-sag formulation for clean vertical applications
  • Cures bubble-free and tack-free in approx. 35 minutes (at 25°C, 50% RH)
  • Transparent 290ml cartridge, 24 per carton – trade-pack ready

The Selsil Ultra Clear Advantage

  • Safe to use in residential kitchens and bathrooms – low VOC, no odour
  • Excellent for bonding dissimilar materials – timber to tile, glass to metal
  • Handles Australian climate extremes – -40°C to +90°C temperature range
  • Works in wet area environments but not suited to continuous immersion
  • 12-month shelf life – long storage reliability for project planning

Best Practices: Do's & Don'ts

Do

  • Apply on clean, dry, solid substrates like glass, metal, and ceramics
  • Use backing rod for deep joints to avoid three-point adhesion
  • Tool immediately with a putty knife before skin forms
  • Store between +5°C and +25°C to maintain product performance
  • Use in temperature conditions between +5°C and +35°C

Don't

  • Don't apply on bitumen, EPDM, HDPE, natural rubber, PE, or oily plastics
  • Avoid applying on wet, frozen, or continuously immersed surfaces
  • Don’t tool after skinning begins – it may compromise the finish
  • Avoid solvent or alcohol-based surface cleaners during curing
  • Do not paint until fully cured – test with paints beforehand
