ELEMINOL JS-140: Antistatic Agent for Acrylic Resin (PMMA)

ELEMINOL JS-140

Antistatic agent with radical polymerization properties for acrylic resin.
Copolymerization with acrylic resin can provide antistatic properties while maintaining transparency.

Typical Properties of ELEMINOL JS-140

Recommended addition amount

It is recommended to polymerize by blending 3 to 7 parts by weight for 100 parts by weight of monomer.

Features of ELEMINOL JS-140

1) Radical polymerizable antistatic agent

Because of copolymerization, antistatic properties (dust adhesion prevention effect) are maintained even after wiping with water.

2) Long-term dust adhesion prevention

Copolymerization with acrylic or methacrylic monomers such as methyl methacrylate (MMA) can add antistatic properties to acrylic resin (PMMA). It reduces surface resistivity to around 10^12-13Ω/m2 and prevents dust from adhering to the acrylic resin surface.

3) Transparency

When copolymerized, it can provide antistatic properties without affecting the transparency of acrylic resin (PMMA).

Issues in Antistatic Acrylic Resins

Acrylic resin (PMMA) is a plastic material with excellent transparency and is used in various applications requiring transparency, such as acrylic panels, water tanks, and various types of lighting. On the other hand, acrylic resin itself does not conduct electricity, and because it is hydrophobic, there is little moisture on its surface to release static electricity.

Although applying an antistatic agent to the surface of the acrylic resin to give it antistatic properties is one possible method, there is concern that the antistatic agent may easily peel off when cleaning with water or alcohol disinfection.

Advantages of using radical polymerizable antistatic agent “ELEMINOL JS-140”

Acrylic resins are produced by radical polymerization of monomers such as methyl methacrylate (MMA). Since the Sanyo Chemical’s antistatic agent, “ELEMINOL JS-140” contains components with radical polymerization properties, it can be blended with the radical polymerization of MMA and copolymerized to give antistatic properties to the acrylic resin itself. It is a polymerizable antistatic agent especially suitable for the casting method, in which antistatic components are easily unevenly distributed on the surface.
