Composites

Siltech’s Silmer reactive materials can be formulated into resins to alter their mechanical properties.  In this manner, these provide additional flexibility, toughness, elongation and impact resistance to composite materials.  Shown in the photo is a brittle epoxy compared to the same epoxy modified with 50% of Silsurf G1018-F.

Also enhanced are softness, biocompatibility, release, lubricity and other properties resulting from the low Tg, COF and surface energy of the silicone polymers.

Siltech Wetting agents, used in small amounts (0.1-0.5%), can lower the surface tension of resins   providing improved wet-out of fibers, foam control and entrained gas release.  This results in improved strength of the final composite.

These non-reactive and reactive Siltech additives provide the surface properties listed about but do not give significant changes in mechanical properties

Silsurf C208

[TOP]

 

This silicone polyether copolymer is very soluble in water and most solvents. Gives hair conditioning, foam stabilization and formulation stabilization in PC formula. In inks and coatings moderate slip and mar resistance, good flow and leveling and a low potential for defects. It can be used in nearly any application where surface tension reduction, surface modification or wetting are desired.
