Inside Corner Box (By the box)

GE UST2200 transition sheet and USM corners are low modulus pre-cured silicone rubber accessories for
flashing and transition applications in the GE Elemax* 100% silicone air & water-resistive barrier system.

Key Features and Typical Benefits
Performance
• Silicone Durability—UST/USM Pre-cured silicone rubber exhibits
excellent long-term resistance to natural weathering, including:
ultraviolet radiation, high and low temperatures, rain and snow,
with negligible change in elasticity.
• UV Resistant—May be left exposed indefinitely to UV.
• Thermal Stability —Remains elastic over a wide temperature
range. Does not harden or become brittle under very cold
conditions and does not soften or melt in high heat.
• Flexible—Low modulus UST/USM silicone rubber imparts low
strain to moving substrate surfaces and maintains flexibility at
transition areas and board joints.
• Permeable—Transition silicone is vapor permeable allowing the
entire air & water barrier system to breathe, not just the coated
wall areas.
Application
• Silicone Compatibility—Full chemical and adhesive
compatibility with all GE AWB silicone sealants, liquid flashing,
and coatings.
• Contact Verification—Product is currently available in
translucent to allow easy visual confirmation of continuous
sealant / liquid flashing contact.
