Product Description
Aculon EC nanoscale thickness (4nm) repellency product is a surface treatment that uses it’s hydrophobicity and oleophobicity characteristics to create epoxy repellent surfaces to control the location of epoxy used in semiconductor packaging. Applications include eliminating die attach epoxy bleed, reduce underfill epoxy keep-out areas around flipchip die, and eliminating EMC mold flash contamination. Added features include: wirebondable when used on a metal wirebond pad, repels: water, oil, flux, solder paste, and many solvents. In general use, it is designed to bond to most metals and certain polymers and resists chemical and mechanical degradation

| Specific Gravity Specific Gravity Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless. | 0.98g/ml | ||||

| Boiling Point Boiling Point The amount of degree’s needed to reach in order to make the substance boil. | 78 °C | ||||
| Flash Point Flash Point The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source. | 13.9 °C | ||||

| Viscosity Viscosity Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application | 2 mPa.s | ||||
