Description

Product overview
  • Passive Purple X 10 kg is an airtight, vapour-control coating designed for fire-conscious façades and substrate protection. Applied by airless spray or roller; available in White, Purple, Black and Cream.

Excelling characteristics
  • Fire class B
  • Raintight while vapour-breathable
  • Airtight membrane
  • UV resistant
  • Anti-fungal treatment
  • Self-cleaning / reduced dirt pickup from UV netting
  • Crack-bridging capability
  • Carbonation blocking and realkalising properties for concrete
  • Protection against salts for concrete in road/transport environments
  • Can be used as protective anti-carbonation coating on concrete
  • Suitable for internal and external applications
  • Smoke tight
  • Allows substrate vapour diffusion while ensuring airtightness
  • Intelligent moisture management

Tested & Certified — fire-rated, watertight & breathable
  • Reaction to fire: Euroclass B-s1,d0 (EN 13501-1, on A1 substrates ≥653 kg/m³) and ASTM E84 Class A (Flame Spread 0 / Smoke 15)
  • Watertight: Watertight Class W1 (EN 13859-2) & water permeability Class W3 (EN 1062-3); near-zero water absorption (EN 16302)
  • Breathable / vapour-open — Sd ≈ 0.6 m (EN ISO 12572)
  • Crack-bridging: A3 (23°C) / A4 (-10°C) (EN 1062-7) & CO₂ / carbonation barrier Class C1 (EN 1062-6)
  • UV-stable (strength increases after 500 h UV); low-emission EMICODE EC2; anti-fungus (rating 0)
  • Kiwa BDA Agrément (BAW-21-214-P-A-UK); Passive House component (phB); US ICC-ES AC212 water-resistive barrier

Why choose Passive Purple X?
  • Efficient application — with an airless spray device a single operator can cover up to ~300 m² of façade protection; rapid two-coat process
  • VOC-free — water-based, no added volatile organic compounds
  • Application methods — airless spray (e.g. Graco) or roller
  • External protection — forms a watertight vapour-control membrane with UV resistance
  • Fire rated — Class B reaction to fire
  • Breathable — permits vapour release while maintaining airtightness
  • KIWA approved and listed certifications

Uses & directions of use
  • Substrates: insulation panels, concrete and masonry, fibre cement boards, engineered wood/OSB panels
  • Surface preparation: remove salt efflorescence, dust, loose parts and standing water
  • Fill holes and joints with fast-setting cement-based product or polyurethane foam as required
  • Apply at substrate temperature T < 5°C (observe substrate temperature considerations)
  • Application permitted on humid surfaces if standing water is removed
  • Do NOT add water or solvents
  • Do NOT apply in direct full sunlight
  • Do NOT apply during rain
  • Apply two coats (spray or roller); allow first coat to dry before applying second
  • Clean tools with water after use
