PPG’s Pro-Seal 815M is designed to be sprayed onto freshly applied polysulfide aerospace sealant to improve aesthetics and cut surface cure time. The clear liquid, which comes ready to use in a non-aerosol, recyclable pump bottle, is sprayed in a light mist onto the wet sealant and helps break the surface tension, allowing for easier smoothing and fairing to achieve final required dimensions and optimal appearance, the company says. It is said to cure the surface of the sealant to a tack-free state in two to three hours at 25°C (77°F), compared with the standard six to 40 or more hours required for untreated sealant to obtain the same condition.
