Expert Verdict — Reviewed by the SuperArbor Pro Desk
SCS2000 is the industry standard for structural glazing and protective glazing joints; use a backing rod and correct joint-width-to-depth ratio to achieve the ±50% movement capability. Always bond-test unusual or coated finishes and primer where GE directs. Choose Bronze for dark mullion finishes and Light Gray for aluminum curtain wall to keep sealant lines discreet.
Follow the manufacturer's safety data sheet and application instructions; uncured silicone sealant requires ventilation and skin protection.
Order GE SilPruf SCS2000 in Black, Light Gray or Bronze for your next structural or weatherproofing job.
