SNP is a specialty chemical manufacturer that engineers products designed to fit the specific needs of all our customers. Alongside our existing and potential customers, we create unique polymers for individual applications as well as provide technical support and continuous product improvement to advance our unique chemistries.
Our partnership allows us to develop custom aqueous polymer coatings and resins that serve many industries and compose a multitude of coating types, including:
Oil and grease barrier coatings
Print quality improvement coatings
Moisture vapor and gas transmission resistant coatings
And much more.
Rheology & Material Testing
At SNP, we also offer rheology testing and material testing to a variety of industries. Our expertise in the rheological analysis and profiling of products and raw materials empowers us to provide dynamic and reliable rheological testing services at an affordable price with a fast turnaround.
Rotational viscometers operate under only one measurable flow condition and relate the torque required to turn an object in a fluid at a known speed to the viscosity of that fluid. The relationship is based on the fluid remaining stationary as an object moves through it, or the object is stationary as the fluid moves past it with the resultant drag caused by relative motion of the fluid and a surface is a measure of the viscosity.
Static and Dynamic Water Retention Tester
The water retention of coatings can be tested statically or dynamically. The water retention is an important characteristic of the coating as the rheology of the coating changes as the free water leaves the coating into the basesheet.
Hercules High Shear Viscometer
The Hercules Hi-Shear Viscometer system measures the flow properties of dispersions and coatings subjected to varying degrees of shear. The Hercules Hi-Shear Viscometer produces continuous results reflecting sample reaction to dynamic shear conditions over time. The shape of the rheogram produced from the Hercules Viscometer can be used to predict flow performance of a material based on changes in shear rate.
Fourier Transform Infrared (FTIR) Spectroscopy is a measurement technique where infrared light is guided through an interferometer and through the sample. The interferogram representing light output as a function of mirror position is related to IR spectrum by Fourier transformation. This technique measures the types of bonds present in the test specimen.
A rheometer is used to measure fluid flow response to applied forces. A rheometer is used when fluids cannot be defined by a single value of viscosity therefore requiring multiple parameters to be defined and measured.
