BoPin 340 Герметик для металлических крыш и панелей

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.

Основные преимущества

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

Подготовка поверхности — 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.
Приложение — 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.
Затвердевание — 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.
Уборка — Remove uncured product with a solvent-dampened cloth. Cured product must be removed mechanically.

Ограничения

Not suitable for PE, PP or PTFE surfaces
Not suitable for bituminous surfaces
Не рекомендуется длительное погружение в воду
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

Советы

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
