## Overview

Dow Automotive U-418HV Beta Seal Glass Adhesive is a high-viscosity, primeless-to-glass urethane adhesive designed for quick, moisture-activated curing at temperatures above 40˚F. It offers a fast driveway time of 2-8 hours, water resistance, and a sag-resistant bead for easy, professional windshield installation without the need for glass primer.

## Description

BETASEAL U-418HV is a primeless-to-glass adhesive. They rely on the moisture in the air to cure. If the temperature and relative humidity are low, the curing time will be longer. They are recommended for use at temperatures of 40˚F (4.4˚C) and above.

Review: Great product - This was my first time installing Windshield glass myself. After lots of research and talking to some professionals I decided to use this product. The 418 dries fast and the HV meaning high viscosity both allow amateur's to more easily set the glass without it sagging too much. I used a Ryobi 18V electric caulk gun for application. The idea is to use the included nozzle at a steep angle with the V facing away from the direction of your bead. This will stand up a high bead of urethane so that a good seal can be achieved when setting the glass. It takes roughly 1 and 1/4 tubes to do a Windshield on a small car. Be sure to get the BETAPRIME primer if you have any exposed metal or freshly painted areas on the pinchweld. You do not need to prime the glass or old urethane.
Review: Gets the job done - Easy to use and works pretty effectively
