Evonik (formerly Degussa AG) 4144, organic silane coupling agent Dynasylan 4144, polyether silane Overview:
As a provider of innovative silane solutions, Evonik Degussa AG has launched a non ionized silane product that enables fillers and pigments to exhibit excellent wetting and dispersing properties in various esters and solvents.
Dynasylan ® 4144 Polyether Silane (Also known as:Silane coupling agent 4144,Adhesive 4144）Helping to regulate rheology, viscosity can be reduced in polymer systems with high component fillers, such as polyester systems or SMC adhesive systems with added aluminum hydroxide additives.
Unlike other oligomeric functional silanes, Dynasylan ® 4144 polyethersilane has chemical polarity but no chemical activity, so this product can be used as a water-based compatibilizer but not as a covalent bonding adhesive.
The allowable working viscosity of Dynasylan ® 4144 polyethersilane in unsaturated esters with added aluminum hydroxide additives is over 250 phr. Moreover, Dynasylan ® 4144 polyethersilane can also prevent sedimentation of its anti-corrosion components in ethylene glycol based coolants.

Evonik (formerly Degussa AG) 4144, organic silane coupling agent Dynasylan 4144, polyether silane application:
Applied in industrial fields such as fillers and pigments, in filler modification, the surface is treated to give hydrophilicity, uniformly dispersed in aqueous systems, without suspension or precipitation, significantly reducing viscosity
Dynasylan ® 4144 polyethersilane can be used directly and is soluble in water and most solvents. It can be added to the mixture of fillers or pigments with resin, or used as a pre-treatment agent for fillers and pigments.
Using Dynasylan in a high-speed mixer ® Spraying 4144 polyether silane onto a stirred bed of fillers and pigments is the best method for pre-treatment of fillers and pigments. In order to achieve optimal filling/pigment treatment, good dispersion of Dynasylan ® 4144 polyethersilane on its surface is necessary.
If the surface area of the filler/pigment is unclear, the initial practical basis for pre-treatment is to add 1% Dynasylan by weight of the filler/pigment ® 4144 polyethersilane. Therefore, the precise Dynasylan ® The usage of 4144 should be obtained from practical experience.
In addition, Dynasylan ® 4144 polyether silane can be used as a lubricant and wetting agent in the glass fiber industry when combined with silane coupling agents. As a non coupling agent silane, Dynasylan ® 4144 polyethersilane can significantly reduce the dispersion viscosity of aluminum hydroxide and other fillers/pigments. Due to its good wetting and dispersing properties, Dynasylan is used under certain viscosity requirements ® 4144 polyether silane can achieve excellent loading of fillers and pigments. In aqueous systems, Dynasylan ® 4144 polyethersilane greatly improves the dispersibility of pigments, thereby correspondingly enhancing the gloss of coatings.
