Product Review

Within your vacuum bagging lay-up, this Breather/Bleeder drapes easily over your laminate, directly below your bagging film, to serve two key purposes.

As a breather, it allows for vacuum pressure to be applied evenly across the entire surface of the laminate. It also permits any gases released during cure to escape. Use the 4 oz. format (#579) for applications working under 40 psi. The 7 oz. format (#1779) can be used at higher pressure cycles (between 40 and 85 psi), and provides a lower amount of surface porosity.

When used as a bleeder, both varieties absorb excess resin applied during the lay-up process. Keep in mind, the 7 oz. will absorb more resin and may result in a dry part without careful control. Bleeder should be thrown away after use.

Both 4 oz. and 7 oz. are available in 60" wide formats.
