INGADA™ SR-103 Neutral Cure Structural Silicone Sealant – Semi-Transparent
Semi-Transparent Neutral Silicone for Natural Joint Visuals
-
The “Clear Joint” Look: Solves the problem of bulky, opaque black lines in modern glass skylights and transparent structures.
-
Long-Term Beauty: Prevents the “yellowed” look common in older transparent sealants by using advanced anti-UV stabilizer technology.

-
Aesthetic Structural Design: Combines structural strength with semi-transparency to create clear, natural-looking joints in glass architecture.
-
Elite Aging Resistance: Lab-tested for 3000 hours of accelerated weathering with ≥80% strength retention and no significant yellowing.
-
Non-Corrosive Neutral Tech: Safe for use on sensitive substrates including coated glass and aluminum without causing chemical damage.
-
High Thermal Tolerance: Maintains structural performance across a broad service temperature range from -40°C to +150°C.
-
High Elastic Recovery: Features an elongation at break of ≥350%, allowing for significant joint movement without cracking or delamination.

Q:Is SR-103 suitable for high-rise glass curtain walls?
A：Yes. It is specifically designed for glass curtain walls and skylights, complying with ASTM C1184 and GB 16776 structural standards.
Q:How does SR-103 perform under extreme weather conditions?
A：It offers a wide service temperature range (-40°C to +150°C) and has passed 3,000 hours of accelerated weathering with ≥80% strength retention.
Q:What is the maximum joint movement SR-103 can handle?
A：SR-103 provides a high movement capacity of ±25%, which is essential for large-scale transparent structures and architectural joints.
Q:Is it safe for use on all architectural plastics?
A：While substrate-friendly, it is not suitable for PTFE, PE, or PP. We recommend adhesion testing on other plastics like ABS or PC before use.
Q:What certifications does SR-103 hold for European and American markets?
A：It is compliant with ASTM C1184, ISO 11600, RoHS, and REACH, meeting the most stringent chemical and performance regulations.
