Integrity And Create A Future

Agricultural wetting and enhancing performance

Description

Agricultural silicone spreading and penetrating agent is a kind of silicone surfactant with super spreading ability. It makes the water surface tension lower down to the 21mN/m at the concentration of 0.1% (wt.). It can lower the contact angle between the spray and foliage, which can enlarge the coverage of the spray. Furthermore, it can effectively promote the pesticide absorbed through the stomatal of leaves, reducing amount of pesticide, saving cost, and reducing environmental pollution. Application

Addtive for metal mold release agents

★RH-288

Used as demolding agent, it has excellent performance and won’t impact following print, stamp and brush.

Used as basic oil of lube. It has excellent lubrication and can be used in lubrication between Stainless Steel and Titanium Steel which is hard to lubricate. It can also be used as lubrication oil of aluminum machine, etc.

Notes: 50% non-ionic emulsion of above silicone oil is available.

Application

It can be used in pesticides, fungicides, herbicides, foliar fertilizers, plant growth regulators and other products.

Super spreading and penetrating property, High-efficient systemic and conduction property, Strong tolerance property of rainfall, can increase the efficiency and reduce the dosage of pesticides.

Excellent lubrication

Release properties

Good printability

Volatile silicone oil

Excellent replacement of D5, the cyclics content meets EU requirements, with REACH Certificate. Unique volatility, fresh skin feel, non-greasy, meeting the needs of various formulations. As an aerosol carrier, non-allergenic, high safety.

Modified silicone oil for personal care

By changing the HLB value of silicone oil to make it more compatible with the formulation system, it can be used as an emulsifier for different formulations.

In formulas with more powder, it can be used as a suspension agent to improve the dispersibility of the powder.

Low viscosity silicone oil

Linear siloxane with cyclics content meeting European Standard. Can be added in formulas such as washing care, make-up, and skin care, with lubricated skin feel, non-greasy. As a dispersion carrier of silicone elastomer, it has a silky skin feel, can be used in makeup formulations.

It can produce a closed moisturizing effect, light-fitting and skin-friendly. Help disperse inorganic fillers, synergistically increase the SPF value of physical sunscreens and improve gloss. Good compatibility with other oils and waxes, can be mixed with hot or cold formulas.

Silicone elastomer

Skin care

As the main matrix or additive of skin care cream, the skin feels soft, silky and dry with a powdery texture and elastic, can cover small wrinkles, bring instant visual wrinkle lightening effect; with good spreadability and slight Extinction effect.

Make-up

It can be used to make-up formulations as a facial oil absorber to achieve a silky matte visual effect; added to makeup primer and foundation can greatly improving the phenomenon of floating powder or makeup dropping out, light-fitting and more natural.

Silica gel blend

Used in hair care essential oil formulations, it can form a film on damaged hair, improve combability and long-lasting moisturizing. It has a smooth, fresh skin feel, with moisturizing and easy spreading characteristics in skin care products, without clogging pores. Upgraded version products using raw materials which meeting European Standard, a better solution for European market.

Coating leveling and defoaming

Leveling agent is a kind of commonly used coating auxiliaries, which can make the coating form a flat, smooth, and uniform film in the process of drying. It can effectively reduce the surface tension of the finishing liquid and improve its leveling and uniformity.
