100% Recoverable Sealant
This recoverable/reusable impregnation sealant reduces sealant and environmental costs.
Use less sealant, cut your water usage and disposal costs and operate in a more environmentally friendly way with 1955/R reusable impregnation sealant from Ultra Seal, Inc.
This revolutionary new thermal-curing impregnation sealant is the first 100% recoverable sealant that can be recycled from your system and reused to seal future castings. Because rinse water is also reused, you can achieve near-zero discharge.
1955/R was designed in the job shop environment, so you can be sure it will perform well on a wide range of castings such as oil pumps, cylinder heads, intake manifolds, oil pans and engine blocks. It is certified to Mil-Spec (MIL-I-17563C) and is listed on the Navy Qualified Product list (QPL-17563).
Lower Costs and Gain Flexibility
- Cut costs up to 75% with minimal sealant consumption, water usage and sewer discharge — Cure life is extended up to four times longer, further reducing costs.
- Process parts faster —Penetrates deeper with shorter impregnation cycles.
- Save on washing chemicals and rinse conditioners —Washes clean using plain water. Conditioners and consumables cost as much as sealant, so cost swings are minimized compared with other “recyclable” sealants.
- Reduce chemistry checks and analysis — Wash water and sealant are filtered, separated and reused.
- Lower scrap costs — Successfully seals a greater percentage of parts in each batch, giving you higher recovery rates.
- Reduce failures — No need to roll machined parts during rise/cure operations, which can cause handling damage. Also no failures from sealant curing in dead-end threaded holes.
- Add to your current impregnation system — We’ll work with you to modify your system or provide a new or refurbished system. Keep wash water clean so water can be used again and again.
- Shorten cycle times. Low-viscosity and high-wicking sealant penetrates deeper into porous casting surfaces than conventional sealants.
- Use with wet vac, dry vac/wet vac and DVP processes.
Get superior performance and durability
- Excellent high-heat stability — Weight loss at 400ºF is less than half of conventional materials. Mil-Spec test rings remain sealed at 50 psi up to 425ºF .
- Unrivaled thermal cycle durability — Thermal shock tested from -125ºF to 425ºF in less than 30 seconds for 20+ cycles.
- Ultra-low shrink — Post-cure shrinkage is one-quarter that of conventional sealants.
