BoPin 790 Fire-Rated Silicone Sealant_benefit

BoPin 790 Yangına Dayanıklı Silikon Mastik

BoPin 790, üstün yangın geciktirici özelliklere sahip, tek bileşenli, nötr kürlenen, yüksek performanslı bir silikon mastiktir. Alevde şeffaf kalır, yanmayı desteklemez ve ateşleme kaynağı kaldırıldığında anında kendiliğinden söner; bu sayede UL94 V-0 alev geciktirici sınıflandırmasına ulaşır. Ürün, atmosferik neme maruz kaldığında oda sıcaklığında kürlenerek, astar gerektirmeden cam, alüminyum, çelik, taş ve çoğu yaygın yapı malzemesine güvenilir bir şekilde yapışan dayanıklı, esnek bir kauçuk oluşturur. Yangın kapısı ve pencere sızdırmazlığı, perde duvar yangın durdurma bandı, elektronik ve elektrikli bileşenlerin alev geciktirici sızdırmazlığı ve yangın güvenliğinin öncelikli olduğu kamu alanlarında neme dayanıklı sızdırmazlık için uygundur.

Yüzey Hazırlığı — Ensure all surfaces are clean, dry and free from dust, grease and old sealant residues. For fire door and curtain wall applications, verify that joint dimensions comply with the relevant fire-rated system design.
Uygulama — 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 wet spatula.
Curing — Allow to cure at room temperature with adequate ventilation. Full mechanical properties develop after 7 days.
Temizlemek — Remove uncured sealant with a solvent before skin formation. Cured sealant must be removed mechanically.

Limitations

Not suitable for structural load-bearing applications
Sürekli suya daldırma için uygun değildir
Not suitable for use in sealed, unventilated spaces or in direct contact with food or drinking water
Not suitable for bonding copper or copper alloy components — copper ions inhibit cure
Not suitable for surfaces containing plasticiser or solvent residues
Do not apply when substrate temperature is below 4°C or above 40°C

İpuçları

This product achieves V-0 flame retardant classification under GB/T 24267-2009. For fire-rated penetration sealing requiring EI or EW rated systems, verify compliance with local fire codes before specifying
Always verify that the intended application complies with local building code and fire safety regulations before specifying
Conduct a compatibility and adhesion test on actual project substrates before full application
Store cartridges upright in a cool, dry location away from heat and direct sunlight
