Urethane Vs. Silicone Sealants for a Windshield

The two most widely used products available for windshield repair are urethane and silicone based sealants. Deciding which to use depends entirely on the type of damage needing repaired.

Urethane

A water-resistant liquid compound, urethane is used by auto manufacturers to glaze windshields. It is also used in the aftermarket repair and replacement of windshields. Very odorous, urethane comes in a can and requires a brush for application.

Silicone

A water-resistant glue-like substance, silicone comes in either a tube or caulking gun. It's nearly odourless and can come in clear or white. It is used to either repair a leak in the seal of a windshield or in the installation of a new one.

Urethane vs. Silicone

Both urethane and silicone can be used to install a new windshield or repair the seal on an existing one. Urethane sealants take a week to cure, while silicone cures within hours. As a water based substance, clear drying urethane is also used to repair minor dings and cracks. Silicone is not recommended for crack repair because it is a thick substance that is not completely clear.
