Theoretical spreading rate
m2/l 9.8 9.8 9.8
BASIC DATA AT 25°C
? solids content approx.................... 49% by volume
? mix ratio ......................................... 4A:1B by volume
? touch dry after ............................... 2 hours (Std Part B)
................................................... 1 hour (RR Part B)
? full cure .......................................... 7 days (Std & RR Part B)
SURFACE PREPARATION
PREVIOUS SUITABLE COAT
? must be dry and free from chalking and contamination and
sufficiently roughened if necessary
? oil and grease should be removed from all surfaces in
accordance with AS 1627.1 solvent cleaning
? substrate temperature must be at least 5?C during surface
preparation, application and curing and at least 3?C above
dew point
? relative humidity should not exceed 75% during application
and before the dry to handle time
APPLICATION INSTRUCTIONS
? mixing ratio by volume 4A:1B
? mix Poly U400 Part A with Poly U400 Standard (Std) Part B
or Poly U400 Rapid Recoat (RR) Part B only
? induction time - none
? pot life at 25°C 5 hours for Standard (Std) Part B, (3 hours
for Rapid Recoat (RR) Part B). Do not use after this time
even if the mix is still liquid
? stir the components and mixed product well using a
mechanical mixer
? this product must be thinned with the recommended
thinner before application
? thinning recommendations are given as a guide and may
vary depending upon substrate temperature and weather
conditions
? the temperature of the mixed product must be above 15?C,
otherwise extra thinner may be required to obtain
application viscosity
? too much thinner will result in lower sag resistance and
slower cure
? thinner should only be added after mixing the components
? freshly catalysed material should not be added to product
that has been mixed for some time
? Valspar recommends the use of coating inspection reports
in compliance with AS/NZS 3894.10,11,12 refer to
Information Sheet I-20 for more information
? for recommendations outside those contained in this data
sheet, refer to Valspar
