BoPin 240 Ekonomik Standart Köpük

BoPin 240, 750 ml'lik aerosol kutusunda bulunan tek bileşenli, nemle kürlenen poliüretan genleşen köpük dolgu macunudur. Atmosferik nemle temas ettiğinde genleşerek boşlukları ve aralıkları doldurur ve mükemmel ısı yalıtımı, akustik sönümleme ve nem direnci özelliklerine sahip sert, kapalı hücreli bir köpüğe dönüşür. Standart genleşme formülü, hassas düşük basınçlı uygulama gerektirmeyen genel inşaat boşluk doldurma, kapı çerçevesi montajı, boru geçişi sızdırmazlığı ve bina bakım işleri için uygundur. Ekonomik konumu, genel projelerde çalışan müteahhitler ve bakım ekipleri için erişilebilir bir seçenek haline getirir.

Preparation — Shake can vigorously for 30 seconds before use. Lightly dampen the substrate with water to accelerate cure. Ensure adequate ventilation.
Uygulama — Attach applicator straw or foam gun. Hold can inverted and apply foam to fill approximately 50% of the gap — foam will expand to fill the remainder. Work from the back of the gap towards the front.
Tedavi — Allow to cure fully before trimming. Tack-free in 8–15 minutes. Trim excess foam with a sharp knife after 30–60 minutes. Full cure in 12–24 hours.
Finishing — Cured foam can be painted or plastered over after full cure.

Sınırlamalar

Must be applied in well-ventilated areas — wear protective gloves and safety glasses during application
Do not use near open flames or ignition sources — contents are flammable before cure
Do not use on polystyrene foam insulation boards — foam solvents may cause damage
Cured foam is strongly alkaline — avoid contact with clothing during application
Do not store cans inverted or on their side
Do not incinerate or puncture used cans
Not suitable for fire-rated penetration sealing — use BoPin 730 for fire-rated applications
Not suitable for movement joints or structural applications
Standard expansion formula not recommended for sensitive aluminium window frames — use BoPin 270 Low-Expansion Foam instead

İpuçları

For best yield, warm the can to 20–25°C before use — cold cans produce less foam output
Partially used cans can be stored with the straw attached if the valve is kept clean — use within a short period after opening
Foam expands significantly — apply conservatively and allow expansion before adding more
UV exposure will cause yellowing and surface degradation of uncovered foam — always cover with paint, plaster or sealant in exposed locations
