Instructions for Use

Application

Apply directly to surfaces by dipping, spraying, brushing, or wiping. Prior to use, dilute material to desired concentration for the specific application. Experimentation may be required to determine the concentration that yields the appropriate coating thickness.

Solubility

MED-4159 is soluble in many organic solvents including aliphatic and aromatic hydrocarbons, chlorinated solvents, and ethers. This fluid is not water-soluble and hydrolyzes rapidly when placed in contact with water. Any solvents used to dilute this material must be moisture-free.

Mixing

Thoroughly stir material to ensure homogeneity. Exercise care to prevent solvent loss during deairing. Accomplish additional dilution for thin film applications by adding appropriate solvent. Mixer design/size/type, blade/propeller type, shear/RPM levels, and heat generated during mixing, are important parameters and should be addressed in order to have an adequately mixed dispersion. Warning: Consult the MSDS for MED-4159 prior to use, as its solvent carrier is hazardous.

Coating and Use

Make sure to apply under a fume hood or in a well ventilated environment. Care should be taken before placing coated mandrels or parts in oven due to the presence of solvent. Reference cure schedule for devolitilization times.

Storage & Handling

Storage and Handling

Most dispersions are stored prior to application. It is important to note that NuSil recommends keeping the dispersion in its original container when possible, tightly sealed and stored below 40º C. Care should be taken to prevent solvent evaporation and contamination during long or short term storage.
