Problems solved by technology

However, although this composition is also excellent in the silicone mist suppression effect, the addition of a compound such as polypropylene glycol has the problem that the composition becomes a migratory component when processed as a peeling product, and the peeling performance is impaired.

Embodiment 1

[0129] 98 parts by mass of polydimethylsiloxane (vinyl valence content: 0.02mol / 100g) with a viscosity of 400mPa·s at both ends containing vinyl groups at 25°C, 2.0 parts by mass of the following average formula (7) Represented polyorganohydrogensiloxane (SiH group / Vi group (molar ratio) = 1.8) having a viscosity of 20 mPa·s at 25°C,

[0130] [chemical formula 4]

[0131]

[0132] and 0.3 parts by mass of ethynylcyclohexanol were uniformly mixed. 3 parts of silicone mist inhibitor I and 2 parts by mass of a complex salt of chloroplatinic acid and vinylsiloxane (approximately 100 ppm in terms of platinum atoms) were added thereto, and uniformly mixed to obtain a silicone composition 1.

Embodiment 2

[0134] Except adding 3 parts of silicone mist inhibitor II, the operation of Example 1 was repeated to obtain silicone composition 2.

Embodiment 3

[0136] Except adding 3 parts of silicone mist inhibitor III, the operation of Example 1 was repeated to obtain silicone composition 3.

Abstract

To provide a silicone mist suppressing agent capable of providing a composition and a cured product which are excellent in silicone mist suppressing effect and storage stability. The present inventionprovides the silicone mist suppressing agent comprising at least one kind of powder selected from an organic powder, an inorganic powder, and an inorganic / organic composite powder each having a volume-average particle diameter in the range of 100-4000 nm. The present invention also provides a solventless silicone composition which contains an organopolysiloxane having a viscosity in the range of25-50,000 mPa s at 25 DEG C and further contains the silicone mist suppressing agent in an amount of 0.1-10 pts.mass based on 100 pts.mass of the organopolysiloxane.

Description

[0001] This application is a divisional application of the PCT / JP2013 / 068759 invention patent application entitled "Silicon Mist Inhibitor" filed on July 9, 2013. The national application number obtained when the original application entered the Chinese national phase is 201380050769.8. technical field [0002] This invention relates to silicone mist suppressants. Specifically, it relates to a silicone mist suppressor capable of suppressing the occurrence of silicone mist in a process of applying a solvent-free silicone composition to a substrate by high-speed coating, and a silicone mist suppressor containing the silicone mist suppressor solvent-free silicone composition. Background technique [0003] The surface of the substrate is highly functionalized by coating the silicone composition on the surface of various papers, laminated paperboards, synthetic films, transparent resins, metal foils, and the like. There are organic solvent-diluted silicone compositions, solvent-f...
