Curran 1000T Coating & Safety Data Sheet

Product Sheet

General Description

Curran 1000T is an advanced two-part 100% solids epoxy coating designed specifically for high temperature immersion service in cooling water and process streams. This coating is an organic/inorganic hybrid that exhibits state of the art coating technology with exponential improvements in performance versus existing polymer technology. Can withstand multiple cycling and steam out events subjected to process equipment. Ideally suited for small diameter tubes:

Heat exchanger tubes (new & used) (straight or U-tube)
Fin Fan/Air cooler tubes
Condenser tubes
Chiller tubes

Benefits:

Outstanding immersion protection in water and hydrocarbons.
Can withstand multiples of heat cycling events with no effect.
Tolerates excursions/steam outs to + 400 (°F) 204 (°C).
Excellent foul release.
Reduction in drag
Coating surface remains slippery even at high temperatures.
High Gloss finish
More thermally stable at higher temperatures than other coatings.
Zero VOC’S (100% Solids) as supplied.

Mix Ratios:

Mixing Ratio by Weight: 100 grams Base to 31.08 grams Hardener

Application:

Below are general guidelines for applying Curran 1000T. Contact Curran International for detailed application procedures.

Surface preparation:

New surfaces should be degreased prior to grit blasting.
SSPC- SP 10, NACE 2.0; SA 2.5 is a minimum surface cleanliness.
Surface roughness: 1.0 Mil minimum surface profile.

Coating Application:

Coating must be fully mixed before addition of solvent (if needed)
Minimum 60:1 airless spray pump

Recommended Dry Film Thickness

Single Coat: 2 – 4 Mils final DFT
- For non-ferrous alloy tubes
2 Coat: 8 – 14 Mils final DFT
- For ferrous alloy tubes
32 – 50 mils final DFT for all other applications
- Tube sheets, channels etc

Environmental:

Apply when substrate temperature is between 60 F and 100 F. Substrate must be 5 F above dew point.

Thinning: (if required)

Thinning: Denatured alcohol, MIBK, or Acetone can be utilized for thinning and cleaning. No more than 25 % of either solvent can be added to the coating. Coating must be fully mixed before addition of solvent.

Holiday Inspection:

Wet sponge testing is recommended with 67.5 VDC.

Repairs:

Should coating be mechanically damaged or a holiday is detected take the following steps to perform a repair
1) Abrade area if the overcoat window has expired.

2) Apply another coat or coats of material to the repair area to require DFT.
3) Once the coating has become tack free, QC repaired areas.

4) Contact Curran International for detailed application procedures.

Working Times:

At 70F (21C) the usable life of mixed material is 60 min. Working times will vary depending on temperature and amount of material mixed.

Storage/Shelf Life:

Store in temperatures between 50F (10C) and 90F (32C) Separate base and hardener will have a shelf life for 2 years when in the original, unopened container that is not damaged and stored at the above temperature ranges.

Health and Safety:

Prior to using this product, please review the appropriate Safety Data Sheet (SDS).

Cure Time:

	50F/10C	60F/16C	70F/21C	90F/32C
Tack Free (Minimum)	12 hrs	10 hrs	8 hrs	4 hrs
Light load (Minimum)	24 hrs	20 hrs	16 hrs	8 hrs
Overcoat (Maximum)	24 hrs	18 hrs	12 hrs	4 hrs
Overcoat w/ solvent added maximum	96 hrs	72 hrs	60 hrs	48 hrs
Full Load	60 hrs	40 hrs	32 hrs	16 hrs
Full Chem	240 hrs	154 hrs	120 hrs	96 hrs

Note:

Full cure should be confirmed by a MEK rub before exposing coating to chemical service.
Applicators note that minimum overcoat window is considered acceptable when the coating has gelled to a state that applying another layer of coating over the underlying coat will not lead to deformations of the underlying coat. This may happen before the coating is in a tack free condition.
