(1) resistance to aging
The two pieces of glass or ceramic tile tied together, will not be the same boring paint (a, B, c) CF brush on top, 1 hour after, the among them a piece of glass placed in 200oC temperature inside the oven baked for 2 hours, and then remove the cooling after the contrast yellowing condition, Huang bianhou severe indicate poor quality, resistance to aging accordingly. The performance of anti - sun radiation is usually good or bad:
The silicon acrylic and acrylic anti yellow Bianxian is superior to that of styrene acrylic paint, styrene acrylic paint is better than vinegar C paint and ordinary paint.
Even if it is not the same as the manufacturer of styrene acrylic paint, yellow will also be some differences, which is the difference in the recipe technology.
(2) washing resistance and water resistance
From the brush like outside to watch: gloss paint of abrasion are more than matte paint, so senior paint for exterior wall coatings are usually semi matte (or shell), (gloss paint for reflective too big, to level the construction requirements and beautiful factors resulting in failure to throughout the selection). Gloss paint resistance is usually more than 2000 times, and some even more than 20000 times. So it is difficult to use a brush to contrast the difference between high gloss paint.
Light or semi matte paint on the water resistance of CF: can brush paint film (evenly coated) on glass, contrast to the dry after immersion in water, sparkling survey, skin, fall degree. The more the bubble, the worse the water resistance.
The same is two kinds of matte paint, the water resistance of different differences:
A, the two film with water pouring, no change is excellent; wet hair and dark hair owe good is in low-grade paint; weak tide of the worst may be substandard products.
B, with a nail scratching about two kinds of dry film, hard good quality, resin binder, water resistance is excellent; soft is poor, the cost is low.
