Question 1

Does SGS-100 meet ASTM C1184 requirements for structural glazing sealants?

Accepted Answer

Yes. SGS-100 is formulated to satisfy ASTM C1184 performance criteria including minimum tensile adhesion, elongation at break, and durability after accelerated heat aging and UV weathering cycles, making it suitable for specifying in curtain-wall glazing systems.

Question 2

What primers are recommended to achieve durable adhesion to glass and aluminum substrates?

Accepted Answer

For glass, a silane-based primer (aminosilane or epoxysilane type) is recommended prior to SGS-100 application. Anodized or thermally broken aluminum profiles benefit from a polyurethane or epoxy primer to meet the long-term bond strength requirements of structural glazing standards.

Question 3

How is the two-component SGS-100 system mixed and dispensed on site?

Accepted Answer

Parts A and B are combined at a 10:1 weight ratio using a static-mix cartridge gun or automated volumetric metering equipment. Pot life is approximately 30–60 minutes at 23°C. The gun-grade viscosity provides direct bead application into glazing channels without slump or flow, even on vertical joints.

Shore A Hardness	35–45
Elongation at Break	>100%
Tensile Strength (cured)	>1.5 MPa
Mix Ratio (Part A : Part B)	10:1 by weight
Full Cure Time (23°C, 50% RH)	7–14 days
