What do F-16's, F-18's and baby carrots have in common? They have all landed on CCS Patch, Nosing, Slurry Binder (PNSB).
PNSB is our popular lo-mod epoxy binder-grout for use in repairing joints and spalls, often located in very tough applications like Navy and Air Force runways, municipal refuse handling facility floors, large vehicle repair shops, machine shops and food processing machines (grinding surface adhesive). Often, PNSB is extended with 4-8 volumes of gap-graded aggregates to provide a durable (5000 psi) surface that is highly resistant to chipping, impacts, point loads and large temperature swings. When used as an extended binder, it has a useful working life of up to 45 minutes at 72°F, so there is time for your best trowelers to properly place the entire batch you just mixed in the mortar mixer.
What is the role of the aggregates? Depending on the size distribution, shape, hardness and quantity used, they can dramatically affect the placement properties, strength, wear, impact resistance and thermal behavior of the grout. It's possible to achieve workable mixes that are only ~10% epoxy with excellent working properties. And unlike cementitious patches, there's rarely a bonding problem and in most cases, priming isn't necessary.
So what's the deal about baby carrots? Well, we can't reveal secrets of our best customers. We can tell you that baby carrots are formed from larger carrots that have been cut and ground. The longest-lived grinding wheels are made with a high mod epoxy and a low mod epoxy in a special combination. Similar wheels handle even harder tasks like pistachio nut hulls.
