Matt protective/fixative water topcoat for glass, by curtain coater and spray

WATERBASED LACQUER FOR FURNITURE

BRAND:

PRODUCT CODE:GO V800/ XXX

MAIN PROPERTIES:

• Optimal hardness and smoothness • High dulling uniformity
• Base to realize every lacquered color • High pigment coverage

VERSION:

V800/ NTR   neutral                                                                  V800/ EXT   Extra white

RECOMMENDED USE:

• Glass

APPLICATION METHOD:

Curtain coater; Spay: pot, airmix, airless

PRODUCT PREPARATION:

Add the adhesion promoter for glass YC M406 to a 2-4% ratio in weight (recommended for curtain coater) or, as an alternative, add YC M419 to a 2% ratio in weight; bring to viscosity according to the application (curtain coater or spray)

CHEMICAL-PHYSICAL PROPERTIES ( 23 °C):

                                             NTR    EXT

Solid content (%) 36 ± 5 48 ± 5 
Specific weight (g/cm3) 1,050 ± 0,050 1,200±0,050 
Viscosity + 2% YC—M406 DIN 4: 70 ± 10 DIN 4: 70 ± 10 
Viscosity + 2% YC—M419 DIN 6: 60 ± 10 DIN 4: 75 ± 10

APPLICATION CARACTHERISTICS :

Maximum verticality (a spray μm wet)      –
 Recommended n of coats (max)           1
Recommended quantities per coat min: 130 – max: 170  Interval between coats                                 –                       
 Spreading rate (m2/liters)                   –

SUBSTRATE PREPARATION:

Properly clean the glass form traces of grease, dirt and limestone with proper cleaners and then make a final
cleansing with AG M500.

PIGMENTABILITY:

Use the range EY M690 XXX from 10% to 18%. Topcoat GO V800/ NTR can’t be pigmented above the 18%; White base EXT is pigmentable up to a maximum of 5 %. Make reference to the specific technical data sheet of pastes for information
regarding coverage, light resistance, etc.
Note: According to the color composition, variations on the topcoat’s viscosity arise. The optimal viscosity for curtain coater application is of about 50 – 80 seconds to DIN 4 pot (already cross-linked product);the pot has to be then verified and reached by adding tap water and/or AY M458 or increased using the thickener AY M453, to be introduced slowly and while stirring. For spray application the ideal viscosity is between the range 30-80” DIN 6

WORKAVILITY:

Topcoat GO V800/xxx guarantees good glass adhesion right after drying; nevertheless for further glass processings(drilling, grinding, beveling…) you need to wait at least 96 hours in order for the fixing action of the coating to be sufficient.

POT LIFE:

After the adding of the gripping YC M419, this additive keeps its efficacy for 24 – 36 hours. After this period, the product can be used again mixing it with fresh product and adding again the gripper to the total quantity.t

GENERAL REMARKS:

• Properly mix the product before use.
• If the product is stored at temperatures between 5 and 35°C, shelf life is 18 months.
• During application phase, for the product, the support and the environment, temperature , must not fall below 15°C.
• Films forming below such temperature do not have glass adhesion, chemical resistance and mechanical proper properties.
• Coatings leftover (cleansing water, cabin water, waste coating) have to be disposed of according to local regulations in force. Do not throw leftovers in sewage.
• Equipment has to be cleansed with water right after use. If there must be removed dry coating films, use AY M460, letting it work overnight, then rinse again with water
