The fiberglass composites were first discovered in the 1940s. When initially fabricated, these new composites were very strong, but their strength declined rapidly during aging. These weakening were caused by a loss of bond strength between the glass and resin. In seeking a solution, researchers found that organofunctional silanes-silicon chemicals that contain both organic and […]

This article will indicate how the Silane coupling agent used in Fiberglass Finishing Process Fiberglass and fiberglass reinforced polyester composites are now essential components in many major applications due to their high strength, high modulus and superior electrical insulating property. Without them, many of the materials we rely on today would not exist. Meanwhile, and […]
In the traditional production of glass fiber, the fiber drawing will increase the fuzz generation, make the filaments hardly bonds together and occurred the fiber breaking easily. In order to facilitate fiber manufacturing, a special organic surface treating agent, usually called fiber sizing, is needed to apply on the surface of fiberglass. It is a thin […]
Fiberglass and its reinforced polyester composites are widely used in aerospace, auto bodies, chemical and automation industries for their high specific modulus, high specific strength and outstanding design ability. Fiberglass and the resin matrix are hardly to achieve satisfactory bond strength at the interface as the surface of fiberglass is very smooth. Fiberglass consists mainly […]
As we all know silane can be used as a silane coupling agent which has two functional groups with different reactivity. One of the two functional groups reacts with organic materials and the other reacts with inorganic materials. Based on that knowledge, today we are going to discuss the below topic: What is the usage […]

Objectives. To evaluate the effect of different silane coupling agents and air-drying temperatures on bond strength of translucent quartz ﬁbre posts to composite resin. Methods. The post surface was etched with 10 vol% hydrogen peroxide for 20 min. A two- liquid coupling agent containing 4-methacryolxyethyl trimellitate anhydride (4-META) and ‘Y-trimethoxysilyil propyl methacrylate (‘Y-MPTS) and two […]
