Description
Zyvax
Sealer 1050 is a solvent-based semi-permanent
sealer for the advanced composites industry which affords
easy application in one step using a wipe-on, let-dry
method. Zyvax
Sealer 1050 is designed to treat both the
chemical and physical bonding sites found on every raw
mold surface. In addition, Zyvax
Sealer 1050 provides the
base needed to extend the life of the release coating and
will allow optimal performance
.
Mold Preparation
1. Tool surfaces should be thoroughly cleaned to remove
all resin build-up, wax, oils, sealers, and other release
agents.
2. Perform a final cleaning of the tool using an
appropriate Zyvax
mold cleaner.
3. If the mold is composite or polymeric, treat with a
Zyvax
mold primer.
Application Instructions
1. Dampen an approved cloth with Zyvax
Sealer 1050
sealer and apply a light and even coat to the entire tool
surface ensuring slight overlaps between wipes to
ensure full coverage.
2. As a guide to achieving a “light coat”, the wet film should
shine, but there should be no runs when applied to a
vertical surface.
3. Continue working across the tool until the entire surface
has been coated.
4. Allow the sealer to cure for a minimum of 15 minutes
prior to applying additional coats.
5. Using the same method, apply additional coats as
necessary for a total of 2 – 4 coats.
6. Allow the sealer to cure for a minimum of 30 minutes
after the final coat has been applied before applying the
appropriate release agent.
Important
The recommended number of coats and cure times are a
general guideline found to be more than sufficient in a
broad spectrum of molding conditions. When molding
products with extreme geometries or experiencing low-
humidity conditions in the shop, the customer may find the
need to extend the cure time between coats and increase
the number of coats applied to the mold. The efficiency of
a release film is best determined through a combination of
tape tests and experimentation.
Storage
Do not store at temperatures above 49 C/120 F. Keep
container tightly sealed to prevent evaporation and/or
contamination. If stored in cold temperatures allow
warming to room temperature before using.
