In the paint and ink industry, the use of silicone is very wide, such as used as defoaming, leveling, wetting, dispersion, feel, anti-stick, etc., and the effect is also obvious, a small amount of addition can meet the needs of the system, the following to introduce silicone feel agent.
The function of hand feeling agent is to increase hand feeling, increase slippiness, resist scratch and wear, prevent adhesion, reduce friction coefficient and other special functions.
Industry although this kind of organic silicon fertilizer to provide feel called feel agent, but feel agent role is to provide not only handle, it can also be used to improve surface smooth degree, increase the paint adhesion resistance effect, increase the resistance to abrasion, reducing surface friction coefficient, etc., and some modified silicone handle agent can help flow flat, help defoaming, help mute powdered directional arrangement, etc.
Many feel agent are large molecular weight on the market of organic silicon, because this kind of silicone can provide better comprehensive performance, the anti-sticking, feel has excellent effect, its action principle is to rely on limited compatibility between and film forming matter, can float in the paint, the formation of organic silicon monomolecular layer, so that the coating has a feel, smooth, prevent ink stick, such as scraping resistance wear-resisting effect. Reactive organosilicon handle agent grafts the reactive group onto the organosilicon, and makes use of the reactive group to cross-link with the film-forming substance. This type of handle agent will not migrate easily and can provide long-term effects.
