difference is chemistry and appearance: 112 Crystal Clear uses Silane Terminated Polymer (STP) and cures completely transparent, while 11FC+ uses polyurethane and is available in black and grey only. 112 has a much faster skin time (~vs ~) and zero sag, but lower elongation (~ vs ~) and a narrower joint width range (6–20 mm vs 10–35 mm).\u003c\/p\u003e\u003ch3\u003eIs it truly transparent after
