The repair of a fractured porcelain surface with a resin composite was investigated. The effects of applying an opaque resin to porcelain surfaces, which were silanated by a ceramic primer from a repair kit or by an experimental silane coupling agent, were studied. The porcelain surfaces were silanated for 10 sec and 60 min. Three types of adherents were evaluated: opaque resin with light irrad...

This study evaluated the effect of 1% hydrofluoric acid (HF) treatment on the bonding of an adhesive cement (Panavia F 2.0) to an indirect resin composite (Estenia C&B). Pairs of composite disks (10 and 8 mm in diameter by 3 mm thickness) were prepared. Adhesive surfaces were pretreated with either airborne particle abrasion or HF etching before being soaked for 30 seconds, five minutes or 10 m...

The main advantages of the use silica instead carbon black in rubber compounds are based on a silane coupling agent. agent to modify surface improves compatibility between and rubber. There two different possibilities modifying by silane: ex-situ in-situ. present work studies differences these processes how they affect in-rubber properties filled SBR compounds.

• Interfacial connecting mechanisms between PDA and silane have been demonstrated. PDA-silane improve graphene dispersion reduce thermal interfacial resistant. modified can greatly enhance conductivity of epoxy. Epoxy composites good properties to meet electronic packaging requirements. Performance TIMs demonstrated by experimentation simulation. With the ultra-fast development high-performance...

Abstract Silica is the rubber industry’s most essential and cost-effective reinforcing filler after carbon black. The silica reinforcement mechanism with a non-polar elastomer complicated by presence of polar functional groups on surface. This nature causes filler-to-filler interaction forming hydrogen bonds. Therefore, sizeable non-dispersed clusters remain in matrix. To avoid these strong fil...

In this study, the use of cotton fiber (CF) as a filler in poly(butylene succinate) (PBS) and the effect of silane treatment on the mechanical properties, thermal stability, and biodegradability of PBS/CF composites are investigated. The results showed that the tensile strength of PBS was improved (15%–78%) with the incorporation of CF (10–40 wt%) and was further increased (25%–118%) when CF wa...

It is well known that the mechanical properties of fiberglass reinforced "phenolic moulding compounds" are significantly enhanced if the glass particles are coated with silane coupling agents before compounding. It has been shown that improvements obtained by using scanning electron microscopy techniques are due to better bonding of phenolic resin to the surface of treated glass fibers. These o...
