Polygem - 307 FR LITE II - Fire Retardant Sculpting Epoxy

307FR LITE II bonds to many materials including metals, wood, fiberglass, concrete, PVC, Plexiglas™ (acrylic), plastics, foams, including EPS, lathing and glass.

NOTE: 307FR LITE II DOES NOT BOND to silicone, polyethylene, polypropylene, or plastic wrap.

Prepare Your Substrate/Surface –

If applying to smooth surfaces such as metals, plastics, glass, etc., surface may be roughened with sandpaper (120 grit) to aid adhesion. Clean surface thoroughly to ensure it is free of dust, oils, release agents, etc.

For Metal Substrates– Abrade the surface to a white metal finish, then wipe down and clean it thoroughly. Apply a fiberglass sheet saturated in a laminating epoxy
to the surface. When possible wrap the sheet around the substrate to ensure a good mechanical bond before applying 307FR LITE II.

Recommended minimum thickness is ¼ in (6.35 mm).

Measure & Mix– After pre-mixing Parts A and B, measure out equal parts 1A:1B by volume. Combine and mix material thoroughly until “streak free”. Large volumes
can be mixed on a flat surface using two trowels. DO NOT mix more than can be applied within the working time of 60 minutes.

When using with Polygem 307 Thickener –First, thoroughly coat gloves and working area with Polygem 307 Thickener to prevent sticking. Knead Parts A & B together while folding small amounts of powder into the mixture. The amount of powder to add depends on the desired working consistency. Continue to fold mixture repeatedly until it is streak-free.

Application: Trowel or spread by gloved hand onto your substrate. DO NOT apply to a surface that is less than 60 °F (16 °C).

WORKING TIME - MATERIAL IS MASS SENSITIVE. More Mass = Less Time to Work. Apply and spread quickly to achieve the maximum working time. Temperatures above 73 °F (23 °C) will reduce working time.

307FR LITE II cures in approximately 16 hours at room temperature 73 °F (23 °C). Elevated temperatures will accelerate this cure time. Full physical properties will be
achieved in approximately 7 days.

Uncured 307FR LITE II can be cleaned up easily with just water. When cleaning cured 307FR LITE II wipe with a mild solvent followed by a water rinse.DO NOT allow water or solvent to pool on the surface.
