Description & Application
Zapit BASE was developed to fill-in all voids and undercuts, or to correct anomalies in models and dies.Zapit is also used to join wax patterns, metal, or porcelain segments together prior to removal from the model. The Zapit system is excellent for:
1. As mentioned above, the Zapit System is the standard in the industry for ‘fixing’ any anomalies (air bubbles, undercuts, base-up areas, etc.), in working dies.
2. Relating cast parts together prior to fabricating a matrix for soldering procedures.
3. Partial and orthodontic laboratories can also use Zapit to maintain the position of clasps or wires on the model, again while producing a matrix for soldering procedures.
4. Zapit is also helpful in holding precision attachments and implant parts in position during complicated fabrication procedures.
5. Zapit ACCELERATOR is used extensively to set or harden traditional cyanoacrylate adhesives for use with model & die repairs; the gluing into position of dowel pins; or quickly adhering glue-on articulators to stone or plastic bases.
Competitive products used for similar applications:
WAXES: Undercut Wax, Sticky Wax, Block-out Wax
PLASTICS: Duralay, GC Pattern Resin
COMPOSITES: Light-Cured CompositesAll of these products require more time to apply, are not as easily shaped, manipulated and molded. They are significantly more expensive to use.
- Simplifies die repairs & preparation
- Improves accuracy of multiple-unit bridges.
- Indicates existence of undercut areas in preparations.
- Eliminates contamination of soldering surfaces
- Improves Economy
- Use of Zapit System is simple, fast and easy-to-control.
- Zapit Base shrinks less than wax. Less shrinkage means less distortion.
- Zapit, while strong, is somewhat brittle and will ‘break apart’ if any portion of the wax pattern is ‘catching’ in the prep.
- Zapit burns-out cleaner than resins.
- Only the amount needed is consumed.

Tech Tips & Product Maintenance
- When applying base, if a large quantity is required, apply in layers rather than one bulk application. Be sure to accelerate between layers.
- When accelerating use a fine mist. Back off to some extent; do not hold the sprayer too close!
- To ensure a smooth surface, apply accelerator first, then base. This action will cause hardening from the inside progressively toward the outer layer.
- To eliminate the possibility of a warped bridge due to wax shrinkage, or to improve the accuracy of fit of long-span bridges, use a razor to separate the various sections of the bridge. Place a drop of Zapit in each joint and apply accelerator to both sides of the junction. Zapit will preserve the relationship without the shrinkage and stress associated with cooling wax. Wax can then be applied over the Zapit for final contour. This technique also exposes nonparallel abutment situations. The Zapit joint will crack upon removal of the waxed bridge identifying the problem before casting. Using Zapit in this manner will also identify undetected undercuts on preparation; the ‘locked’ wax segment will break-away from the wax structure upon removal from the die.
- Keeping Zapit Tips working like new is very easy. When a Tip clogs, and we know it will, simply place the clogged Zapit Tip into the bottle of Tip Cleaner. Place the second, supplied Tip on the bottle. Thereafter, whenever a Tip becomes clogged, simply ‘rotate’ it with the Tip that has been in the Tip Cleaner. Continue to repeat and rotate tips as is required. Proper care will increase your return on the use of this excellent and helpful product.
