1. Solvent for reaction

With its high dielectric constant and solvation effect, DMI™ accelerates anionic nucleophilic reactions, and reactions that place with solvation of cation.
DMI™ is thermally and chemically stable with excellent dissolving power for organic and inorganic compounds.
Since DMI™ is extremely useful as a reaction solvent, it is used in various reactions to synthesize medical drugs and pesticides.

2. Detergents

DMI™ has strong dissolving power and is used in detergents such as paint peeling agents and photoresist stripping agents.^5）

Paint peeling agents

A patent example for DMI™ used in paint peeling agents of acrylic, melamine, urethane type resins, which have sufficient paint removability and excellent workability.
The results after the evaluation test is shown in the table with number of changes for each of the following, ⊚ when changes are observed in the coating and primer resin; O, when the primer resin peels off by disintegration or swelling; Δ when peeling off is observed by partial dissolution or disintegration or swelling; X when no changes are observed (5 test samples were used)

※Acrylic curable paint with melamine coated on parts of polyolefin resin with primer
(Coating I and coating II have different chemical compositions for the coating and primer resins.)

Photoresist Stripping Agents

A patent example in which DMI™ has been used for photoresist stripping agents that are not corrosive to silver and silver alloys and has high peelability for photoresist and photoresist deteriorated layers^7）

※Peelability:◎＝ Eliminable,○＝Slight remaining,×＝ not eliminable

※Corrosive :◎＝Remain the same,○＝Discolored parts occur,
×＝ Discolored ・gloss level variation・stripped membranes parts occur

【Test Method】

The substrate used for evaluation was subject to dry etching and then immersed in a photoresist stripping agent at 70℃ for 10 minutes, and the peelability was evaluated using optical and electron microscopes.

Silver alloy corrosivity: A silver alloy formed on a glass substrate was immersed in a photoresist stripping agent at 70℃ for 10 minutes and evaluated for corrosivity using optical and electron microscopes.

3. Additives

DMI™ is used as an additive for adhesives, rubber processing aids, and electrolytes.

Adhesives

A patent example in which proper shape is retained, bonding duration is retained without decreasing the initial tack, has excellent and powerful adhesiveness that even bonds with coated paper for which adhesion is difficult, and used in the stick adhesive that has polyvinyl pyrrolidone as the main component.^8）

※a)Adhesive composition: 27% of polyvinyl pyrrolidone, 8% of sodium stearate, 50% of water, and 10% of glycerin

※b)Bonding strength test: Breaking rate of paper when high quality papers are stuck together and peeled after 3 days

※c)Hardness: Penetration distance (mm) by a 12.5 g needle in 10 seconds. Smaller the penetration distance, greater the hardness

Rubber Processing Aids

A patent example of use in a modifying agent of rubber processing aids that can avoid deterioration of rebound resilience due to addition of processing aids, and deterioration in processability due to dispersion of carbon black. Evaluation of extrusion processability using a rubber composition according to the ASTM D2230-77A method

a)The amount of liquid rubber added is based on 100 g of SBR

b)The test specimen exposed to the atmosphere at 60℃ was measured according to JIS K-6301

c)Measured using a portable skid tester on the road surface of ASTME-303-74 specifications at 23℃
(manufactured by Stanley UK)
