corners? Isn't it faint?
※ Is there any blurring, repelling points due to remain oil film orsilicone dust on the entire window glass?

Step５Correction immediately after application

Step５ Correction immediately after application(if there is a problem with the finish)①repellent Spots due to Silicone dust

②repellent Spotsdue to remain oil filmNote) Immediately after application, the following corrections can bemade if the application is basically completed within 3 minutes, within 3
minutes in summer, and within 5 minutes in winter. If you overlook the
problem, or if you can't fix it, you'll have to peel it all off and re-apply.

③faint① Silicone repellent; With a scraper, peel off the coating film that is still wet andthe silicon residue together, then apply a primer, and apply IRUVCut Coat immediately.
②Remain Oil film; Apply a primer to the repelling points, then apply IRUV Cut Coat
immediately.
③Faint point； Roll the roller only at that point to eliminate the faint.

Kitchen Paper Towel

Scraper with blade(Use Polypropylene “PP” or polyethylene “PE”)❖When the coating surface is not dried (immediately after the application,
within 10 minutes)①Wipe off the wet coating film with paper towel ,then remove by scraper with blade.
※Make sure not to cut the fingers by blade.
※The coating liquid will adhere to the cutting edge of the scraper, so be sure towipe it off with kitchen paper towel.
② After peeling, use a glass cleaner to remove the oil film. The white liquid of theglass cleaner makes it easier to see the coating film left behind. At this time, the partthat still has peeling residue is peeled off again with a scraper.

❖When the coating surface is harden.(More than 1 hour after application.)①Use the roller handle and sponge for peeling, apply Remover to the entire coating.
※Apply only from top to down same as IRUV Cut Coat application process.
②After applying remover about one minute, peel off the film with the scraper blade.
※When the coating is still hard, apply remover again. Peel off with the scraper
after one minute.(Repeat) Exchange blade of a scraper frequently. Otherwise, thecracked blade might be damaged to the glass.
③ After peeling, use a glass cleaner to remove the oil film. The white liquid of
the glass cleaner makes it easier to see the coating film left behind. At thistime, the part that still has peeling residue is peeled off again with a scraper.

●You don’t have to measure the Remover. But it is about 20g per 1 sqm.

Failure cases

Case

The coating liquid could not adhere theglass because the preparation step is not
perfect.

Case

The amount of coating liquid is not enoughbecause you did not press the roller withenough power.
Make sure to apply evenly. Press the roller
with pressure ,especially the beginning of
application. You can confirm the evenness
during the application.

Check

Make sure to the preparation step.

Check

Case

The coating repelled because thepreparation step was not enough.
Or you took the sealing ( Silicone) when you
apply.

Case

Roll the sponge for a long time and there is
the distortion on the coating surface.

Check

Ideally, you complete the application within
3min for 1 sqm. ( it depends on thesituation.)

Check

Case

Check

Put the masking tape before the preparation
step. Make sure not to remain oil film.

The coating surface made whiten becauseof condensation during the night time.

Take 2 days for the application. On the firstday, complete the preparation. On thesecond day, apply Primer and IRUV.
Complete the application until noon andtake the time for dryness.

Results
All cases are necessary to re-apply.
The key of successful application is preparation andcircumstance.
Also we recommend to apply with two people for the
beginner applicators.
※One person apply and another could check the coating states.

Points for the application◆After the application◆①Do not touch the window glass for one day after the application.
②Please notice the clients not to clean up the window glass for a month after the application.
※After one month, clean up with soft cloth with water or diluted neutral detergent.

Notice the cleaning method to the cleaning company.（Also notice not to touch the metal part of squeegee）③Please notice the clients not to put the tape, sticker or poster on the coating surface.

◆Notes for the wired glass◆ Breakage of the glass can not be guaranteed due to the thermal cracking①It could be broken or cracked by the thermal effect to the wired glass.
It does not matter whether coated or non coated. ※Since the metal and glass of the expansion rate is different.

◆Notes for the application on the window film◆①When you apply on the window film, please change the roller every 5 to 7 sqm application.
※The coating surface might be cloudy gradually when the resin of film melt and continue to accumulate to the roller.
There might be the part of repellent the coating because the underlying process is only by alcohol.

◆Notes for the storage◆①The coating agent does not remain open container lid since the curing reacts with moisture in the air. In addition, thecoating agent, be stored in a cool and dark place.
※Do not storage on car trunk or in the refrigerator (there is a risk of deterioration.)◆How to measure the glass size◆①Area is calculated to two decimal places (rounded to two decimal places)
Ex1）1360mm×1200mm=1.632㎡, so it’s 1.63㎡ ／ Ex2）1360mm×1210mm=1.6456㎡ so it’s 1.65㎡.

②The amount shall be to the nearest 1 (rounded to the first decimal place less)
Ex1）1.63㎡×25g=40.75g so it’s 41g. ／ EX2）1.65㎡×25g=41.25g so it’s 41g.

Float Glass

Features
一Common transparent plate glass.
Various sizes and thickness.

Points to remember
It is possible to apply from inside andoutside.

It is used in a variety of locations.

Figured Glass

Wired Glass

Paired GlassHeat absorbing
glass

One side of the glass is uneven, opaque glass.
Such as a bathroom and washroom, are suitable tocut-off the sight from the outside.

Metal mesh or metal wire is enclosed into a glass.
Fire protection and shatterproof purpose.
There is a transparent or opaque glass, the shape ofthe mesh are several kinds.

It can be applied to the unevensurface.
However, it can not be peeled off after
the application.
There is a possibility to occur the heatcracking after the application. Mainly
winter dawn (east side). The heat cracking
occurs when the tension exceeds theallowance because the temperature
difference between the areas which enter
the direct sunlight and not is increased.

Sandwiching the film between two sheets of plate
glass, it was bonded by applying heat and pressure
glass.
Not scattered even when the crack. When the object
is impacted to the glass, it is less penetration than
the float glass of the same thickness.

Because of the film in the glass, there
is a possibility to occur the heatcracking.

It is added slightly the metal component whichmakes the colored glass.
By absorbing solar heat, reduce the amount oftransmitted heat.

It is possible to apply from inside andoutside.

Vacuum Glass

Double-pane Glass

Low-E Glass

Features
Vacuum is to make a vacuum layer between two
sheets of glass from a scientific principle that does
not conduct heat, it exhibits high thermal insulation
performance about 4 times of a single and 2 timesof the multi-layer glass.

Enclosed dry air between two glass sheets. This
increases the heat insulating effect. Characterizedby high thermal insulation and prevention ofcondensation

Low-E glass, which was coated by a special metal
film on one side glass surface of the multi-layer
glass.

Heat reflecting
glass

A metal oxide is adhered on the surface of the glass,to reflect solar radiation. However, the reflectedsolar remains in the ground, there is also a problemof causing heat island phenomenon.

Toughened Glass

It is rapidly cooled after heating the float glass at
about 700 °.
Compared to same thickness of float glass, there isthree times of the resistance to wind pressure
