There are many types of epoxy, designed for a myriad of applications. POXY-SHIELD was designed specifically to meet the needs of boatbuilders. POXY-SHIELD is used for coating (encapsulating), gluing, making fillet putties, and fiberglassing. POXY-SHIELD seals out moisture, reduces maintenance, and increases resale value. As discussed in WoodenBoat and other magazines, epoxy is THE resin for use on wooden boats.

POXY-SHIELD is virtually indispensable in Stitch and Glue construction. This clear, pale amber, low-viscosity resin (used with one of the hardeners) forms a surface that is clear, tough, and mar-resistant. The resin requires no costly thinners, and includes no hazardous diluents such as BGE. For those builders choosing not to use the encapsulation system, POXY-SHIELD is still the resin used for fiberglass application and is our most popular glue, used with or without the addition of fillers, depending on the application.

When using as a glue, for making Stitch and Glue fillets, or for use as a fairing compound, add one or a combination of our fillers. This versatilitymeans that only one resin is required for all aspects of your boatbuilding project. There is no need to buy a variety of costly pre-mixed products-- you make just what you need. Use on all types of woods, most metals, and some plastics. The 100% solids formulation is waterproof upon curing and does not shrink. Heavy clamping pressure is not required, and when mixed with one of the fillers, has gap-filling properties so that precise joints are unnecessary. POXY-SHIELD coverage:
* Coating applications - each coat: 300 to 350 square feet per gallon.
* Fiberglass sheathing application (includes all coats): 50 to 60 square feet per gallon.

These figures are approximate for estimating materials. Add 10% minimum for waste and variables.

POXY-SHIELD Resin is mixed with POXY-SHIELD Hardeners at a 5:1 ratio (five parts resin to one part hardener by volume or weight). Our graduated mixing containers make this easy.

PART B - POXY-SHIELD HARDENERS

Use FAST Hardener when quick curing is necessary or for use in lower temperatures (down to about 40° F is possible, although cure time increases as temperature decreases). Use SLOW Hardener where longer cure time is required or in warmer temperatures. SLOW Hardener is recommended for fiberglass sheathing (although at temperatures below 65° F the resin is harder to wet out). IMPORTANT NOTE: Hardeners can be mixed together allowing the builder to vary cure time and pot life to better suit the application, as long as the 5 to 1 resin/hardener ratio is maintained.

For further information, please see the EPOXY TECHNICAL MANUAL.

NOTE: Pot life cannot be accurately stated without setting parameters. Heat is the factor that controls cure time, but heat is affected by the volume of resin mixed and the shape of the container. If 8 oz. of resin/hardener is mixed in a wide mouth container at 70° F, the following cure times can be used for comparing the fast and slow hardeners.

FAST HARDENER: Pot life is approx. 10 to 15 minutes, with partial cure in about 5 to 6 hours.
SLOW HARDENER: Pot life is approx. 25 to 30 minutes, with partial cure in approx. 6 to 8 hours.
