مانع تسرب الأسقف والألواح المعدنية BoPin 340

BoPin 340 is a single-component, moisture-curing MS polymer sealant specifically formulated for metal roofing systems, metal cladding and panel joints. Based on modified silane polymer technology, it cures at room temperature to form a durable, highly flexible rubber with exceptional movement capability and excellent adhesion to all common roofing metals without primer. The non-corrosive formula is safe for use on galvanised steel, aluminium, copper and pre-coated metals, and the paintable surface allows colour-matching to roofing systems where aesthetics are a requirement. Vibration-resistant once cured, it maintains joint integrity under the repeated thermal cycling and structural movement typical of large metal roofing structures.

المزايا الرئيسية

Exceptional movement capability — ±50% accommodates significant thermal expansion and contraction in metal roof panels
Excellent adhesion to all common roofing metals including galvanised steel, aluminium, copper and pre-coated metals — typically without primer
Non-corrosive — safe for all metal types, no risk of electrochemical corrosion at the joint
Paintable after cure — allows colour-matching to roof coating systems
Vibration-resistant — maintains bond integrity under structural movement and wind loading
Solvent-free, low odour formula — suitable for use in occupied or partially enclosed structures
Wide application temperature range — -10°C to +40°C

تحضير السطح — Ensure all metal surfaces are clean, dry and free from oil, grease, rust and loose coatings. Lightly abrade glossy or heavily coated metal surfaces to improve adhesion. Remove any existing sealant residues.
التطبيق — Cut cartridge tip at 45°, load into sealant gun and apply with steady, even pressure into the joint. Tool within 20 minutes using a spatula dampened with soapy water. Apply masking tape for clean joint lines.
المعالجة — Allow to cure at room temperature. Avoid rain contact for at least 24 hours. Full mechanical properties develop after 7 days. Paint only after full cure.
تنظيف — Remove uncured product with a solvent-dampened cloth. Cured product must be removed mechanically.

القيود

Not suitable for PE, PP or PTFE surfaces
Not suitable for bituminous surfaces
لا يوصى به للغمر المستمر في الماء
Temperature resistance is -40°C to +90°C — for dark metal roof surfaces in extreme climates that may exceed 90°C surface temperature, conduct pre-project testing
Not suitable for structural glazing or primary load-bearing applications
Do not apply when substrate temperature is below -10°C or above +40°C

الإرشادات

For metal surfaces with existing paint or coating, conduct an adhesion test before full application — lightly abrading the surface significantly improves bond strength
In tropical or high-humidity climates, allow the substrate to dry completely after rain before applying — moisture on the surface affects initial adhesion
Apply masking tape along both sides of the joint for clean, professional lines — remove immediately after tooling before skin forms
Store cartridges upright in a cool, dry location — avoid heat and direct sunlight
For roof joints subject to ponding water, ensure joint is fully tooled to a concave profile to shed water effectively
