Transom Pourable Compound

To estimate the volume and NidaBond material requirements, please fill in the dimensions of your transom in "a", "b", "c" and "Thickness" above.

NIDA-BOND POURABLE TRANSOM COMPOUND is ceramic filled polyester exhibiting exceptional physical properties. In particular, the compressive strength has been documented by an independent testing laboratory to be 3,895 psi (ASTM 695). This is several times that of plywood and 8 to 10 times that of PVC foam. In addition, the failure mode shows elastic yielding before failure. This makes the NIDA-BOND POURABLE TRANSOM COMPOUND material an excellent choice for critical applications such as coring transoms on power boat hulls.

There are three methods of employing the NIDA-BOND POURABLE TRANSOM COMPOUND material as a transom core

A. Specially Designed Hull Liner

By appropriately designing the hull liner at the transom, a gap can be created into which the Nida-Bond Pourable Transom Compound can be poured or pumped. Special consideration needs to be given to the details of bonding the liner to the hull so that a minimum of added time and material is required to seal the cavity.

The Advantages Are:

• The laminate to core bonds are exceptional
• The cycle time and labor are greatly reduced
• The absence of wood is a marketing advantage

B. Use of Transom Jigs

An alternative method that does not require retooling before being able to utilize the Nida-Bond Pourable Transom Compound material involves the use of reusable transom jigs, although other material will work also.After the hull is laminated, the jig is set in place and taped all around. The Nida-Bond Pourable Transom Compound material is poured into the gap. After it has gelled, the jigs can be removed. Depending on the choice of material and release system employed, some surface preparation may be required in order to ensure adequate bonding of the subsequent laminate.An alternative to the above method involves skinning out the backside of the hull jig with 1 1/2 ounce mat prior to setting it in the boat. This provides a superior core to laminate bond.Next, a suitable laminate is added to the backside of the core or the 1 1/2 once mat. Because of the physical properties of the Nida-Bond Pourable Transom Compound, it may be possible to reduce the laminate compared to that which is required for other cores. This should only be done after appropriate testing is conducted.

C. Filling the Cavity

Introducing the material into the cavity can be done either manually or by using dispensing equipment. It is critically important to insure that sufficient catalyst levels are employed and that thorough mixing takes place. Hand mixing can be an effective way to guarantee consistently takes place. The NIDA-BOND POURABLE TRANSOM COMPOUND material is truly an exciting new product, being successfully employed by quality conscious, efficiency minded boat manufacturers.

Using a temporary HDPE dam - . This is the least efficient way

Using the hull liner as the dam - Hull foam floatation is typically used to seal the liner/hull joint so as to prevent leaking of the transom material into the bilge.

Using an FRP stringer as the dam - The aft end of the stringer assembly "sweeps up" to form a 1 ½" gap at the transom. It gets taped in at the transom when the assembly is taped in.

Using a separate FRP part as the dam - This is laminated off line, trimmed and taped in place.
