Questions & Answers
COATINGS > NACURE Catalysts
Should I use Free Acid or Latent Catalyst?
While acid catalysts provide the fastest cure and lower curing temperatures, blocked or latent catalysts are typically chosen for systems requiring greater package stability. In addition, troublesome catalyst-pigment interactions can be reduced or eliminated with the use of blocked catalysts.

COATINGS > K-KAT Tin Free Catalysts
Which K-KAT should I use to replace DBTDL?
Different K-KAT products seem to work better in different systems, The Bismuth catalysts tend to provide the most similar cure speed/pot life to DBTDL. The latest and most hydrolytically stable Bismuth catalyst is K-KAT XK-651
back to top
Which K-KAT is recommended for waterborne 2K polyurethane systems?
K-KAT would be the most selective for the polyol/NCO reaction, but it needs to be incorporated wither in the NCO component or added as a third component. K-KAT XK-614 could be added to the waterborne polyol component.
back to top
Which catalyst do you recommend to replace organomercury catalysts?
K-KAT XK-604, XK-617, and XK-618. They do not contain mercury, tin, or lead. They are efficient and less expensive than mercury catalyst. The XK-618 is the best cure profile match to organomercury, but it is the most likely to result in gassing if there is a trace amount of water present. The XK-604 is the least likely to result in a water reaction.

COATINGS > K-FLEX Polyesters
Which K-FLEX polyesters will provide the hardest films?
The higher the viscosity of the K-FLEX polyester, the higher the hardness. K-FLEX XM-337 and K-FLEX 188 would be the two hardest materials, and the XM-332 would be the softest.
back to top
Do K-FLEX polyesters have primary or secondary hydroxyl groups?
They are 100% primary hydroxyl groups.
back to top
Can I formulate lower VOC systems with higher viscosity K-FLEX polyesters?
Yes, the high viscosities are reduced very efficiently with low levels of solvent addition to break the hydrogen bonding. Also, the narrow molecular weight distribution provides efficient viscosity reduction.
back to top
Are K-FLEX polyesters suitable for waterborne systems?
Yes, they are hydrophobic, so special care should be used to incorporate them. Preblend with whatever co-solvent is available and then add with good agitation before adding any additional water.
back to top
Do K-FLEX polyesters have an acid number?
No, they do not have any acid functionality. As a result, K-FLEX will not catalyze the reverse hydrolysis reactions and they are compatible with polyaspartates.

What is the activation temperature for Disparlon Powder Thixotropes in epoxy coatings?
Epoxy with solvent: 60-80 ° C for 30 minutes.
Epoxy non solvent: 70-90 ° C for 30 minutes.
Cure Agent: 40-60 ° C for 30 minutes.
Also, see cooling instructions.

How to treat Disparlon Powder Thixotropes in epoxy coatings on cool down?
With the activation temperature between 60-80 ° C
- Cooling with stir to 55 ° C will give you a thick fluid structure with a rating of 3.
- Cooling without stir will give you a stiff liquid with a rating of 4.
If you overheated the activation temperature to above the recommended 80 ° C
- Cooling with stir to 50 ° C will give you a thick fluid liquid with a rating of 3.
- Cooling with stir to 70 °C will give you a stiff liquid with a rating of 5.
- Cooling with no stir will give you an almost solid, agglomerated product with a rating of 2.
Rating Scale: 1 (low structure) to 5 (high structure)

How to use Disparlon , , , , and .
- Put the product in at room temperature.
- Heat the paint to its recommended activation temperature.
- After 30 minutes of the temperature being at activation level, put product into can.
- Follow cool down instructions to reach optimal structure.

What's is the easiest paste incorporation for a Disparlon product?
When added to a filled system (whether it is enamel or a clear coat with flattening material or fillers).
- After the grind, before any letdown.

LUBRICANTS > NALUBE KR Alkyklated Naphthalene
What are the advantages of alkylated naphthalenes versus other synthetic based fluids?
Alkylated naphthalenes, our NA-LUBE KR Series, offer an unmatched combination of thermal, thermal-oxidative and hydrolytic stability, additive response and lubrication characteristics, both as the primary base fluid and as a modifier for petroleum and other synthetic base fluids.

Does King have additives for "food grade" lubricants?
Yes. We can fulfill most additive requirements with products conforming to FDA CFR 178., Lubricants with Incidental Food Contact, and approved for HX-1 by NSF. In addition, we have approval for alkylated naphthalene base fluids which are excellent for severe thermal-oxidative applications, NA-LUBE KR FG grades.

LUBRICANTS > NALUBE BL Base Oil Blends & Eco - Label
Is there a package designed specifically for environmentally friendly lubricants?
Yes! NA-LUBE BL-EL is an ashless multi-functional package specifically designed for use in ester-based lubricants and hydraulic fluids. It was the first package to gain qualification for use in the appropriate base fluids conforming to the European Ecolabel requirements.

LUBRICANTS > NALUBE Extreme Pressure (EP)
What is the difference between active and inactive sulfur in EP additives?
Simplified, inactive sulfur is sufficiently tightly bound that it will not readily react with copper, while active sulfur is less tightly bound and will react with copper. There are places for both and our NA-LUBE EP line contains both. Typically lubricants and metalworking fluids use inactive sulfur EP additives if yellow metals (copper and its alloys) are present. Heavy duty applications, like gear oils and machining steel, may require active sulfur to accomplish the EP performance objectives.
