2,4,7,9-Tetramethyl-5-decyne-4,7-diol >98.0%

As a typical Gemini surfactant, Surfadol 541 provides multifunctional properties such as dynamic surface tension reduction, foam control, water sensitivity reduction, and viscosity stabilization. Available in solid, liquid or powder form, Surfadol 541 is widely used as wetting agent or anti-foaming agent in waterborne coatings such as electro-deposit coatings, industrial coatings, etc., as well as water-based inks such as gravure inks, flexo inks and inkjet inks. The unique product can prevent surface defect problems such as fisheyes, crawling, and cratering on low-energy substrates, compared to fluorosurfactant or silicone surfactants.

Oilfield Cement Additive Dispersant Salt Water by Midas IP

MID-C202 is a cement friction-reducing additive which will reduce the apparent viscosity and improve the rheological properties of cement slurry. The improved rheological properties result in reduced frictional pressures during pumping, and turbulent flow can be achieved at lower pumping rates. With a reduction in a slurry’s apparent viscosity, the slurry can be mixed at a higher density than normal by reducing the mixing water, and the slurry is still pump able.

The functions and properties of cement slurries containing MID-C202 are very similar to slurries containing MID-C201 except MID-C202 can be used in slurries with salt concentrations greater than 18% (BWOC) and can be applied in wells above 110℉. The recommended dosage is 0.1% -1.2% (BWOC) depending on slurry’s weight, well’s temperature and solids to water ratio.

MID-C202 is a strong material so it is recommended to do lab tests and find optimum dosage.
