|
| | Two-component acrylic-polyurethane sealer. | | |
| Designed mainly to penetrates and seals interior and exterior wooden surfaces.
| | |
| Provides high filling properties.
Good sandability.
Highly resistant to UV.
Penetrates and seals wooden surfaces.
Excellent flexibility.
Suitable to be topcoated by almost all kinds of lacquers. | | |
| | • Method of Application : | Conventional spray. | | • Mixing Ratio : | (by volume)
Comp.A Comp.B Thinner (S507 “known as Acrysol”)
4 1 0.75
Note: Dilution by thinner S507 is recommended only if conventional spray application is used. No dilution is required for airless spray application. | | • Mixing : | Stir well before application in order to ensure that a uniform consistency is achieved.
Material which has begun to set must be discarded. | | • Pot life : | 2 hours (higher temperatures will shorten the potlife sharply). | | • Cleaner : | Clean applying tools by thinner S507 “known as Acrysol”. | | • Curing : | The reaction between components A and B can not be guaranteed unless a temperature of at least 10°C is maintained for the mixture and the substrate until complete curing. Temperature of substrate should be at least 3°C above the dew point to avoid moisture condensation during application. | | • Note : | When recoating, a special attention should be given toward drying times.
Coated surfaces by HARDTOP Lacquer should not be exposed to water, chemicals, or mechanical stresses before it is fully cured. |
| | |
| | • Component B : | HT drier. | | • Color : | Hazy. | | • Volume Solids : | 30.9 % (ASTM-D2697). | | • Flexibility : | Excellent | | • Solvent Splash and Spill Resistance : | Fair | | • Recommended film thickness : | 30-50 microns “dry”. | | • Theoretical spreading rate : | 7.7 m2/L at 40 microns “dry”. | | • Water resistance : | Excellent | | • Abrasian Resistance : | Excellent | | • Chemical Resistance : | Good | | • Number of Coats : | 1-3 | | • Specific Gravity (mixed) : | 0.97 kg/L (DIN 51757). | | • Packaging : | Component A 3.6 L in metal can.
Component B 0.9 L in metal can. |
| | |
| Coating performance is, in general, proportional to the degree of surface preparation. Surface must be clean, undamaged and free of oil, grease, and other contaminants prior to coating.
It is recommended to apply HARDTOP Sealer over natural or dyed sanded wood. | | |
| | • Dry to Touch : | 2 hours (ASTM-D1640).
| | • Dry to Handle : | 24 hours “minimum recoat time” (ASTM-D1640).
| | • Note : | Drying times can be affected by many factors such as temperature, ventilation and coat thickness. Higher temperatures will shorten the drying times. |
| | |
| HARDTOP Sealer has to be kept in a cool and well-ventilated place, protected from heat and direct sunlight. HARDTOP Sealer is classified under highly flammable materials.
Shelf life is one year from packing date in unopened original containers at 10 to 40°C. Containers should be kept tightly closed.
Safety:
Well-ventilated conditions should be provided during application.
Do not breathe or inhale mist.
Wear air mask and avoid skin or eye contact. | |
