BoPin 260 Mastic d'étanchéité pour fenêtres et portes toutes saisons MS

BoPin 260 is a single-component, moisture-curing MS polymer sealant specifically formulated for window and door perimeter sealing and general indoor and outdoor joint sealing applications. Based on modified silane polymer technology, it cures at room temperature to form a durable, flexible rubber with excellent adhesion to aluminium, glass, concrete and masonry — typically without primer. Unlike silicone-based window sealants, the MS polymer formula is paintable after cure, can be applied to slightly damp surfaces, and produces no corrosive byproducts during cure. Suitable for both interior and exterior applications across a wide temperature range, making it a versatile choice for professional window and door installers working across varied climate conditions.

Principaux avantages

Paintable after cure — compatible with most water-based and solvent-based paint systems, unlike silicone alternatives
Can be applied to slightly damp surfaces — practical advantage in humid or tropical climates
Excellent adhesion to aluminium, glass, concrete and masonry without primer
Solvent-free, isocyanate-free formula — safe for use in occupied buildings
Good elongation (368%) — accommodates thermal and structural movement at window and door joints
Non-corrosive — safe for all metal frame types including aluminium and galvanised steel
Suitable for interior and exterior applications

Préparation de la surface — Ensure all surfaces are clean and free from dust, grease and old sealant residues. Can be applied to slightly damp surfaces — avoid application during active rain or when surfaces are wet with standing water.
Application — Cut cartridge tip at 45°, load into sealant gun and apply with steady, even pressure into the joint. Tool within 15 minutes using a spatula dampened with soapy water. Apply masking tape for clean joint lines.
durcissement — Allow to cure at room temperature with adequate ventilation. Full mechanical properties develop after 7 days. Paint only after full cure.
Nettoyage Éliminer le produit non polymérisé à l'aide d'un solvant approprié avant la formation d'une pellicule. Le produit polymérisé doit être éliminé mécaniquement.

Limites

Ne convient pas aux surfaces en PE, PP ou PTFE
Ne convient pas aux applications de vitrage structurel
Non recommandé pour une immersion continue dans l'eau
Ne convient pas aux surfaces contenant des résidus de plastifiants ou de solvants.
Not suitable for direct application to glass surfaces under direct UV exposure — use BoPin 220 silicone for glass-to-glass or UV-exposed glazing applications
Ne pas appliquer lorsque la température du substrat est inférieure à 4 °C ou supérieure à 40 °C.

Conseils

The key advantage of 260 over silicone alternatives is paintability — specify this product when the joint will be painted over as part of the finished decoration
In tropical and high-humidity climates, the ability to apply to slightly damp surfaces reduces installation downtime after rain
Not suitable for UV-exposed glass surfaces — for glass-to-glass or glass-to-frame sealing where UV exposure is a factor, use BoPin 220 silicone instead
Conservez les cartouches à la verticale dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directe du soleil.
