Expast Acrylic Exterior Paste – EXPAST
Product introduction
Description
Acrylic copolymer based, ready to use, flexible, filler and smoother paste for exterior surfaces.
Application Areas
- Concrete
- Plaster
- Ytong
- Wood
- Mineral Surface
- Old painted surface
- It has high resistance against water, humidity and impacts. It shows excellent adhesion on the substrates because of pure acrylic binder.
- Time and labor saving due to application easiness.
- Cracks are filled easily and paint consumption is reduced.
- Water based, human and environment friendly. High water vapor permeability, allowing building to breathe.
Advantages

Detection and analysis
1 Total acidity (points)
Taking 10 ml working fluid to the conical flask, and adding phenolphthalein indicator of 3 to 5 drops. Titrating above-mentioned solution by 0.1 M sodium hydroxide standard solution from colorless to red. The quantity (ml) of 0.1 M sodium hydroxide standard solution is called the points of total acidity.
2 Free acidity (points)
Taking 10 ml working fluid to the conical flask, and adding bromophenol blue indicator of 2 to 4 drops. Titrating above-mentioned solution by 0.1 M sodium hydroxide standard solution from yellow to blue. The quantity (ml) of 0.1 M sodium hydroxide standard solution is called the points of free acidity.
3 Accelerator detection
Taking a certain amount of working liquid to the fermentation tube, and putting 2 to 3 grams amino acid. A few minutes later, observing the amount of gases.
Instructions for use
When continuous use, the effective concentration is reduced, so it is necessary to regularly measure the sugar content of the tank and adjust the degreaser concentration to make it within the range of the use process
Packing, storage and transportation
Plastic drum :25KG/ drum
Store in a cool, dry place. Do not drizzle
Carbonization is an indispensable intermediate process in the steel process. After phosphating, the batch material has good surface quality and long die life after formation. The main reasons are as follows:
1, the phosphating film can be firmly attached to the metal surface, the crystal gap is very strong adsorption of a large number of lubricating oil (more than 13 times the amount of oil absorption of the untreated surface) when the metal is squeezed, the lubricating oil in the microhole extrusion thereby reducing the friction between the deformed metal and the mold.
2, the plasticity of the phosphating film is strong, can be deformed with the deformation of the metal matrix, and even when the sharp cornea is squeezed, the phosphating film can be well covered in the sharp corner.
3, the thermal adhesion of phosphating film is good, general steel cold extrusion, due to deformation caused by the temperature of only 300 degrees Celsius far below the thermal boundary of phosphating film.
In the cold extrusion process, under certain temperature conditions, phosphating and lubricating oil will react chemically to produce zinc fatty acid with strong lubricity, which can play a role in strengthening lubrication.
