[/additional]Details:

Orca Guard is an ISO NPG thixotropic, polyester gel coat that has great weather, heat and water resistance. It can be used on small to large FRP parts at an ambient temperature.  It cures at room temperature with the addition of methyl ethyl ketone peroxide (MEKP) initiator.

This white gel coat is available with and without wax. Gel coat with wax is typically used for a final tack free hard surface cure. With wax there is no need for PVA, wax paper or the addition of surface seal.  Without wax is usually used for initial layers of gel coat.  It cures tacky which makes it unnecessary to sand between layers.

Uses:

-Mold construction

-Manufactured parts

-Cosmetic gelcoat repairs

-Yacht/Boat construction and repairs

-Spray up process

-Hand Lay-up application

Application:

-Work in a well-ventilated area.

-Use gel coat at room temperature. Ideal temperatures are between 70-95°F

-Wear safety clothing including gloves and safety glasses.

-If using a gel coat gun/spray gun, styrene monomer can be added up to 10% by volume to thin the gel coat. Thinning the gel coat gives it a better flow when spraying.  It can also reduce brush marks when brushing.

-If adding in pigments to color the gel coat, add before the MEKP catalyst. Add up to 1% pigment to resin by volume.

-MEKP catalyst should be used between 1-2% based on volume of the resin. The amount of catalyst used will vary depending on temperature and desired speed of gel time. It is important not to under or over catalyze.

-Apply with a spray gun, brush or roller.  A gel coat gun will give the best cosmetic results without much sanding needed after cure.  A paint spray gun can be used but it is important to wash immediately after use to prevent gel coat from clogging it up. 

Available Sizes:

Quart, Gallon, 5 Gallon and Drums. Call for pricing of drums.

Handling and Storage:

Store in a cool, dry area away from sunlight or heat sources. Polyester gel coat has a limited shelf life.  If stored for too long, it will gel in the can without the addition of MEKP catalyst.

If a paint spray gun is used for spraying, be prepared with acetone to clean the gun immediately after you finish spraying, or else the gel coat will harden in the gun.

Uncured gel coat can be dissolved and removed from tools and equipment using acetone.  It should be disposed of in accordance with local, state and federal regulations for hazardous waste.
