Description: CeRam-Thane 300 is a two-component catalyzed polyester polyurethane engineered
to provide color and gloss retention, abrasion and impact resistance, and flexibility
along with a high degree of resistance to most environments. It is recommended as a
topcoat for CeRam-Kote ceramic epoxy coatings when color and gloss retention is
important.
Suggested Uses:
Tank Exteriors, Externals of Tank Cars, Structural Steel, Chemical Plants, Pulp and
Paper Mills, Bridges, Petroleum Refineries, Offshore Platforms, Fertilizer Field
Equipment and Plants, Topcoat for Floors.
TECHNICAL DATA
Volume Solids: 53%, depending on color
VOC: 3.4 lbs/gal (412 g/l)
Number of Coats: One
Dry Film Thickness: Recommended film thickness is 1-3 mils (25-75 microns)/coat DFT
Cure Time: To Handle: 20 hours at 55°F (12.8°C), 6 hours at 75°F (23.9°C), 2-3
hours at 95°F (35°C), Full hardness after 7 days at 75°F (23.9°C)
Surface Preparation: Bonding strength depends on proper preparation of the surface to be
protected for long-term performance of the product. The substrate
should be free of oil, grease and salt-chloride contaminations.
Cleanliness is the most important step to produce a coated surface
that will perform and last. If used as a topcoat for CeRam-Kote epoxy
coatings or if CeRam-Thane 300 is topcoated over itself, the first coat
must not be completely cured or adhesion will be very poor.
Recommended maximum topcoat time for CeRam-Thane 300 to be
applied over itself is 24 hours at 55°F (12.8°C); 10-12 hours at 75°F
(23.9°C); 4 hours at 95°F (35°C). Do not coat when temperature is
within 5 degrees F of the dew point. Excessively humid air contacting
the surface before it has cured may result in a non-glossy finish. Poor
cure will result if the coating is cured at temperatures below 40°F
(4.4°C). If dew or moisture comes in contact with the surface before it
is cured, loss of gloss will result.
Mixing Ratio: Two (2) components Part A (base) to one (1) component Part B
(curing agent) by volume
Mixing: CeRam-Thane 300 is a two component product and requires thorough
mixing before use. Pour CeRam-Thane 300 Part B (curing agent) into
CeRam-Thane 300 Part A (base). Shake with an air-powered shaker
or mix with an air-powered Jiffler mixer two (2) to three (3) minutes or
until thoroughly mixed.
Pot Life & Shelf Life: Pot life for CeRamThane 300 is 12 hours at 55°F (12.8°C), 3-4 hours
at 75°F (23.9°C), 1-2 hours at 95°F (35°C). CeRam-Thane 300 is
best used within one year. Preferred storage is a dry enclosed area
under 85°F (29.4°C).

Product Data Sheet 2
Application: Spray apply for best results using conventional or airless. The air
source must be dry. Conventional air equipment: Binks 19, 62, 18
or 7; Devilbiss JGA or MBC fluid tip 0.048 to 0.065; air cap 7-13
CFM, fluid hose 3/8“ diameter, pot pressure 5-30 psi, atomization
pressure 40-60 psi, Airless sprayer: 30:1 or more airless pump
equipped with agitator, orifice 0.015-0.021, tip angle 40-60 degrees,
pressure 2800-3000 psi; hose 3/8“ high pressure.
Thinning: Recommended thinners are Xylene or Toluene.
Climate: Use CeRam-Thane 300 only if the substrate and temperature is above
40°F. No coating should be permitted when the substrate is wet from
rain or dew, when surface are less than 5 degrees F (3 degrees C)
above the dewpoint and holding or when relative humidity is greater
than 85%. Moisture will inhibit the catalyst reaction and CeRam-
Thane 300 will not cure or perform properly.
Holiday Detection: CeRam-Thane 300 is classified as a thin-film coating and should be
tested for defects and holidays using a 67½ volt, wet sponge spark
detector set at 80.000 ohms resistance, such as a Tinker and Rasor
model M-1.
Cleanup: Purge and clean spray equipment within thirty (30) minutes of the final
spray. Flush equipment with Acetone or Isopropanol (99% pure) until
solvent sprays clear. Disassemble and clean equipment to
manufacturer’s recommendations. Material left in spray equipment will
solidify and damage equipment. Use precautionary measure
applicable to any catalyzed material.
