Slow Setting and Quick Cure Asphalt emulsifier MK-II for Slurry sealing
It is well known that water and asphalt will not mix, except under carefully controlled conditions using highly specialized equipment and chemical additives. The blending of asphalt cement and water is somewhat akin to an auto mechanic trying to wash grease from his hands with water only. It is not until a detergent or soapy agent of some type is used that grease can be successfully removed. The soap particles surround the globules of grease, break the surface tension that holds them, and allow them to be washed away. Some of the same physical and chemical principles apply in the formulation, production, and use of asphalt emulsion.
The Emulsifier is to make a dispersion of the asphalt cement in water, stable enough for pumping, prolonged storage, and mixing. Furthermore, the emulsion should break down quickly after contact with aggregate in a mixer, or after spraying on the roadbed. Upon curing, the residual asphalt retains all of the adhesion, durability, and water-resistance of the asphalt cement from which it was produced.
Our company is Xinxiang Tongda Road New Technology CO.,ltd.
We have a complete line of asphalt emulsifiers. Our asphalt emulsifiers are used in all types of emulsions from slow set to cationic quick set emulsions. Our specialty is cationic slow set and rapid cure emulsifier known as MK-I and MK-II.
MK-II T Technical Data Sheet
Slow set and rapid cure emulsifier
1. MK-II is a versatile, 100% active, this type emulsifier useful for the cost-effective production of Slurry seal asphalt emulsion.
2.MK-II is one of the leading emulsifiers for this application and has been proven to give excellent mix, set, and cure characteristics on a wide variety of aggregates.
3.Emulsions made with MK-II tend to have a more rapid cure than emulsions made with competitive materials. this is particularly important when Slurry sealing is applied under conditions of low temperature and/or high humidity.
Starting use level for laboratory evaluation is 1.5-2.5%, by weight of emulsion. MK-II emulsifier solutions require an acid neutralization to a pH of 2.5-3.0 with HCL.
MK-II emulsifier is available in bulk quantities (20-30 Ton) every month and in 200 kg drums. It is available from our manufacturing location in Xinxiang, China.
Storage and Handling
Refer to MSDS prior to handling this material. Avoid water contamination during handling and storing. For ease of pumping it is recommended to keep the product at 100° - 120°F.
