Product Description:
PVA film is separated easily from hydrophobic plastic and released
just as easily from various organic materials that have a little
polarity, it can be used as a mould release film for the
unsaturated polyester epoxy resin or other thermosetting resin. PVA
film forms a barrier between parts and mold surfaces that are still
curing. It is also resistant to solvents and yet is water-soluble.
Features:
- Purpose: PVA release film is primarily used as a release agent and
surface protection material in composite molding. It creates a
barrier between the composite part and the mold surface, preventing
the part from sticking to the mold during the curing process.
- Release Properties: PVA release film has excellent release
properties, allowing for easy removal of the cured composite part
from the mold without causing damage or leaving residue. It helps
to achieve a smooth and high-quality surface finish on the
composite part.
- Compatibility: PVA release film is compatible with various types of
molding materials, including polyester, vinyl ester, epoxy, and
other thermosetting resins. It can be used with different mold
surfaces, such as fiberglass, carbon fiber, and metal molds.
- Application: PVA release film is typically applied to the mold
surface before the lay-up or infusion process. It is commonly used
in conjunction with mold release wax to ensure a release from a
composite mold. It can also be used as a barrier in open air gel
coat applications.
- Water Solubility: PVA release film is water-soluble, which means it
can be easily dissolved in water after the part has cured and
released from the mold. This allows for easy cleanup and removal of
the film from the mold surface.
- Surface Protection: In addition to its release properties, PVA
release film provides a protective layer for the mold surface. It
helps to prevent damage, scratches, or contamination during the
lay-up and curing process.
- Shelf Life: PVA release film has a limited shelf life and can
degrade over time when exposed to moisture or high temperatures. It
is important to store the film in a cool and dry place, away from
direct sunlight and humidity, and follow the manufacturer's
recommendations regarding shelf life and storage conditions.
- Safety Considerations: When working with PVA release film, it is
important to follow safety precautions and guidelines. This may
include wearing protective gloves and eyewear, ensuring proper
ventilation, and handling with care.
