ADSEAL PRODUCTION 4550 is a single component moisture curing neutral cure silicone with excellent elasticity. This silicone is specially designed for window manufacturing. It has outstanding adhesion on most PVC (flexible and rigid) and anodized aluminium. It bonds very well to most paints, glass, wood, and fiber reinforced plastic (FRP). It cures fast, thereby increasing your production speed. It is easy to apply with a manual or pneumatic gun (cartridge or sausage) or pneumatic pump (5-gallon pail or 55-gallon drum). It has low volatile organic compounds (V.O.C.) and little odor. ADSEAL PRODUCTION 4550 adhesive sealants are resistant to permanent temperatures from -40°C to 232°C (-40°F to 450°F) and intermittent temperatures from -51°C to 260°C (-60°F to 500°F). It meets the following standards:
-
ASTM C920, Type S, Grade NS, Class 50, Use M, G, A, O
-
AAMA 802.3, 803.3 and 805.2
-
Meets ASTM E84 / UL 723 (flame spread index = 0 / smoke development index = 20)
