Description
SC 5000 coring is a SprayCore transom coring compound supplied in a 5 gallon pail for marine composite repair and build work. ITW Performance Polymers describes SC 5000 as a pourable or injectable transom coring material formulated as a lighter and stronger alternative to plywood, with low shrinkage and strong bonding properties.
SC 5000 coring Benefits
- Pourable or injectable format helps crews fill transom cavities and shaped spaces.
- Designed as an alternative to plywood in marine transom construction or repair.
- Low shrinkage after cure supports more stable composite repair geometry.
- Excellent bonding properties are called out in ITW product information.
- Gray 5 gallon pail package supports shop use without moving to drum quantities.
This material is aimed at marine teams that need a syntactic coring compound rather than wood core stock. It can be useful when rot, water damage, or design requirements make plywood less attractive. Because transom structure is load-bearing, the product should be selected with current technical data, correct catalyst, qualified surface preparation, and a repair method approved for the boat or composite part.
SC 5000 coring Applications
- Marine transom repair where a pourable core is needed.
- Composite build work that calls for injectable syntactic coring material.
- Replacing selected wood core areas with a low shrink compound.
- Shop repairs that need gray 5 gallon pail packaging.
- Jobs where bonding to prepared fiberglass surfaces is part of the process.
Application and Ordering Notes
MEKP catalyst is not included with this pail, so order and stage compatible catalyst separately before work begins. Confirm cure time, temperature, mixing, surface prep, and cavity fill method from current documentation. For related coating and composite products, browse Chemical Concepts coatings.
