QUANTUMUV SELF-SEALING CLEAR URETHANE VARNISH
PRODUCT DATA SHEET
PRODUCT DESCRIPTION
QUANTUMUV is a self-sealing clear urethane varnish finish system specially formulated for marine
brightwork. This high solids 2K hybrid urethane provides superior protection and beauty to all timber
substrates. By chemically bonding to the wood on a molecular level this low VOC, easy to apply coating
provides a permanent, flexible finish in even the harshest marine environments. This high solids, high
build finish system is available in satin and gloss and can be applied via spray or brush application. For
interior or exterior use above the water line only.

SURFACE PREPARATION
The surface preparation advice provided, and equipment suggestions, can be used as a guide.
Preparation techniques and results will vary according to individual conditions, equipment age and
other factors. Testing on a non-critical area should be carried out prior to full-scale preparation.
Any cracks in the timber should be epoxy filled or splined with timber prior to sanding. Radius all edges
to ensure that no sharp corners remain. Oxalic acid based teak cleaners can impair cure of QUANTUMUV
and should be avoided. If timber is badly weathered, scrub with the grain using a stiff bristled wire
brush and running water to remove all grey timber from the surface before sanding.
Remove all previous coating systems and contaminants.
The surface of the timber should be mechanically removed until coloration is even and the original
timber tone has been exposed. All substrates must be sanded using no finer than 150 grit sandpaper.
If bare timber has been saturated with salt water at any stage, scrub well with fresh water to remove
salt deposits from the timber before commencing sanding.
If the timber gets wet after the final sand water spots may appear. Re-sand these areas with 150 grit
paper before sealing.
MIXING
To 2 parts 99-ST Base slowly add 1 part 99-ABR-2001 Brushing Activator by volume. Agitate to ensure
complete mixing. Though not normally required, a 10-30% reduction with EMC SR-95 Brushing Reducer
may help to achieve desired results, especially on finish coat. Additional reduction may be used for
prime/seal coat depending on substrate porosity.
Example: 8 oz. 99-ST Base, 4 oz. part 99-ABR-2001 Activator, 1-4 oz. Brushing Reducer as desired.
APPLICATION
Brushing: QUANTUMUV can be applied at a greater rate than a standard varnish. This system is selfleveling - do not overwork the surface and aim to keep wet edge times under 2 minutes depending on
the temperature. For large flat surfaces high density foam rollers offer the best means of coverage and
flow (some brush tipping may be required but most overlap and foam will disappear as the coating
continues to flow). For small areas and railings, dense synthetic brushes yield the best results.
Spraying: QUANTUMUV can be applied by air atomized spray gun (fluid tip 1.4-2.0). The use of 99-A-100
Spray Activator is strongly recommended.
PRIME/SEAL COAT: Apply heavy coat using adequate pressure to completely wet out wood grain.
Brush/roll with the grain, making sure the surface becomes completely saturated with coating. Wait
approximately 4 hours between coats (or when paint is dry through if accelerated). For best results,
apply first two coats on Day 1, wait at least 12 hours and sand with 320 or finer grit before final coat.
More coats may be necessary with excessive grain raise. Sand with 320 or finer grit sandpaper between
applications. Repeat above procedure until desired build and smoothness is obtained.
FINAL COAT: Sand the prime/seal coat with 320 grit sandpaper, being careful not to sand through the
coating. Reduce 10-20% as needed with EMC SR-95 Brushing Reducer to achieve desired appearance.
NOTE: Application of these product systems requires recommended temperature/humidity conditions
and film thickness ranges. The material, hangar, and substrate temperature should be no lower than 45F
before, during, and after application. Do not apply paint materials to surfaces less than 5F above dew
point, or to surfaces warmer than 125F. Substrate temperature should be minimum 45F to maximum
125F.
PRECAUTIONS
Use with adequate ventilation and proper respiratory protection. See MSDS for complete details of
composition and precautions.
