BoPin 380, mastic de façade résistant aux intempéries

BoPin 380 is a single-component, neutral-cure oxime silicone sealant formulated specifically for curtain wall and building facade weatherproofing applications. formulated to the highest performance tier of neutral-cure weatherproof silicone technology, it delivers exceptional elasticity, movement capability and long-term resistance to UV radiation, ageing and extreme temperature fluctuations. The non-sag thixotropic formula maintains its position on vertical facade joints without slumping, and the product bonds reliably to powder-coated metals, glass, coated glass, ceramic tiles, aluminium composite panels and masonry — the full range of materials encountered in modern facade systems. Supplied in 590ml sausage packs for professional contractor efficiency.

Principaux avantages

High movement capability — ±30% accommodates significant thermal and structural movement in facade systems
Exceptional elasticity — elongation at break ≥400%, maintains seal integrity under repeated joint cycling
Outstanding UV resistance — resists ageing, yellowing and degradation from prolonged solar exposure
Stable performance from -50°C to +170°C — suitable for extreme climate markets including Middle East, Central Asia and North Africa
Non-sag thixotropic formula — maintains position on vertical and overhead joints without slumping
Excellent adhesion to powder-coated metals, glass, coated glass, ceramic tiles, aluminium composite panels and masonry
Meets GB/T 14683-2017 standard — high-end certified silicone series

Préparation de la surface — Ensure all surfaces are clean, dry and free from dust, grease, old sealant residues and loose coatings. Clean metal surfaces with isopropyl alcohol and allow to dry completely before application.
Application — Cut cartridge tip at 45°, load into sealant gun and apply with steady, even pressure into the joint. Tool within the working time using a spatula dampened with soapy water. Apply masking tape for clean professional joint lines.
durcissement Laisser sécher à température ambiante dans un endroit bien ventilé. Éviter tout contact avec la pluie ou l'eau pendant au moins 24 heures. Les propriétés mécaniques optimales sont atteintes après 7 jours.
Nettoyage — Éliminer le mastic non polymérisé à l'aide d'un solvant avant la formation d'une pellicule. Le mastic polymérisé doit être retiré mécaniquement.

Limites

Not suitable for structural glazing or primary structural assembly
Not recommended for movement exceeding ±30%
Non recommandé pour une immersion continue dans l'eau ou la construction d'aquariums
Déconseillé pour une utilisation dans des espaces totalement clos et non ventilés.
Déconseillé pour les surfaces contenant des résidus de plastifiants ou de solvants.
Ne pas appliquer lorsque la température du substrat est inférieure à 4 °C ou supérieure à 40 °C.

Conseils

For facade joints subject to high thermal cycling — particularly in desert and continental climates — ensure joint width is designed to keep actual movement within the ±30% capability
Apply masking tape along both sides of the joint for clean, precise lines — remove immediately after tooling before skin forms
Although neutral-cure, this product uses oxime chemistry — ensure adequate ventilation during application in enclosed or interior spaces
Always conduct a compatibility and adhesion test on actual project substrate combinations before full application
For joints requiring movement capability above ±30%, please contact us for product recommendations suited to your specific application.
