More than phenolic resin; and a methacrylate one layer, or monolayer equiva- silane will bond through styrene lents, of silane is usually applied to crosslinking to an unsaturated the surface. This results in a tight polyester resin.
Limitless silanes
A silane coupling agent will act as an interface between an inorganic substrate (such as glass, metal or mineral) and an organic material (such as an organic polymer, coating or adhesive) to bond the two dissimilar materials.
Silane Coupling Agent
Any silane coupling agent with three alkoxy groups on silicon should bond equally well to an inorganic substrate, but matching of the organofunctional group on silicon with the polymer type of the resin to be bonded will dictate which silane coupling agent should be used in a particular application.
Silane Coupling Agent
By mixing a slurry of the inorganic materials in a dilute solution of the silane coupling agent, a highly uniform and precise surface treatment of the inorganic material can be obtained. A high shear, high speed, mixer is used to disperse the silane coupling agent into the inorganic materials.
Silane Coupling Agents
Many conventional coupling agents are frequently used in combination with 10-40% of a non-functional dipodal silane, where the conventional coupling agent provides the appropriate functionality for the application, and the non-functional dipodal silane provides increased durability.
Silane Coupling Agent
Silane coupling agents are primarily used in reinforced plastics and electric cables composed of crosslinked polyethylene. Other uses include resins, concrete, sealant primers, paint, adhesives, printing inks and dyeing auxiliaries.
