ACCUREL® DS 110 is a highly loaded “dry silane” concentrate based on PP and AMEO (3-Aminopropyltriethoxysilane). It is bifunctional, possessing a reactive primary amino group and hydrolysable ethoxy silyl groups.
Typical Applications
The dual nature of the dry silane concentrate ACCUREL® DS 110, allows the chemical binding of inorganic materials (e.g. glass, metals, fillers) with organic polymers (e.g.thermosets, thermoplastics, elastomers) functioning as an adhesion promotor, crosslinker and/or surface modifier.
Benefits at a glance
ACCUREL® DS 110 is used in thermoplastic applications to improve:
In the presents of humidity, the ethoxy groups of ACCUREL® DS 110 can hydrolyze to form reactive silanol groups, which can bond to a variety of organic groups or on inorganic fillers. Upon hydrolysis ethanol is released. The organophilic amino end can react with suitable polymers. To enhance the bonding due to hydrolysis, catalysts like organo metal components like DBTL can be added separately.
The curing of the alkoxy groups depends on time, temperature and thickness of the parts and the available moisture.
ACCUREL® DS 110 may be used with such polymers as epoxy, phenolic, furan and melamine resins, PA, PBT, PC, ECA, PP, PVB, PVAC, PVC, PS, nitrile rubber, polyesters, acrylates and silicones.
- The embedding of fillers and flame retardants, like ATH or MDH especially in HFFR compounds
- The embedding of fillers for highly filled compounds with inorganic or carbon-based materials to achieve high thermal conductivity
- The adhesion on solid surfaces
- The heat distortion temperature and hot set performance of various polymers and cable compounds
- Mechanical properties, such as flexural strength, tensile strength, impact strength and modulus of elasticity
- Moisture and corrosion resistance
- Electrical properties, for example CTI value or dielectric constant, volume resistivity
