Sealers help protect composites molds and tooling from operational damage

Zyvax® mold sealers condition mold and tooling surfaces to protect composites manufacturing investments from chemical and physical damage arising from the natural bonding tendencies of the molding process.

Zyvax® PreFlight™

PreFlight™ is a tool surface conditioner developed to treat both the chemical and physical bonding sites found on every “raw” tool surface. It was developed to dramatically increase both the life of the tool and the performance of the release agent. PreFlight™ has been certified by the South Coast Air Quality Management District meeting stringent requirements on low VOCs (Volatile Organic Compounds), no HAPs (Hazardous Air Pollutants), no ODCs (Ozone Depleting Chemicals) and no GWCs (Global Warming Compounds).

Zyvax® Sealer GP

Sealer GP is a high modulus, clear, flexible film with superior substrate adhesion that forms a protective shield on the mold or tool surface.

As a conditioner it is designed to treat both the chemical and physical bonding sites found on every “raw” mold surface. In addition, it provides the base needed to extend the life of, and provide optimal performance from, the semi-permanent release agent.

Zyvax® Sealer SF

Sealer SF increases the duty cycle of the mold and protects the mold surfaces from wear and damage. It provides a hard glossy finish on most mold surfaces, reduces the break-in time for new molds and restores vacuum integrity. It has been designed for use on metal or composite molds for most thermoplastic or thermoset resins.

Zyvax® SealProof™

SealProof™ is a solvent-free mold sealer that delivers a durable, visible film with superior abrasion resistance. SealProof™ eliminates the break-in time for new molds and reduces mold down time by aiding in the extension of the number of releases achieved between cleaning cycles. SealProof™ has been developed to overcome porosity in mold surfaces such as wood, high-density tooling board, carbon-graphite, steel, and all types of composites.
