The Use of Mixed Silane Coupling Agents

Overview Organofunctional silanes used as coupling agents or primers for the adhesion of organic polymers to mineral substrates are almost invariably used at more than mono-layer coverage of the mineral surface. Regardless of the method of application, they are believed to condense on the mineral surface to build an oligomeric siloxane network capable of forming […]

Why silane used in fiberglass

When organic polymers are reinforced with glass fibers or minerals, the interface, or interphase region, between the polymer and the inorganic substrate is involved in a complex interplay of physical and chemical factors. These factors are related to adhesion, physical strength, coefficient of expansion, concentration gradients and retention of product properties. A very destructive force […]

How Silanes used as adhesion promoters for paints, inks, coatings, and adhesives

Organofunctional silane coupling agents function as adhesion promoters for PICA in a manner similar to the way they function as coupling agents for fiberglass and mineral-filled composites. In most cases the general conditions are similar, i.e., an organic polymer is to be bonded to an inorganic substrate. Bond failure mechanisms in PICA adhesion systems are […]

What Is A Modified Silane Adhesive

Modified silanes adhesives were developed and launched in Japan during the 80’s, due to the great advantage of these elastic adhesive compared to polyurethane adhesives, its use is highly increase both Europe and America markets.   Modified silanes are one component adhesives which react and cure under the action of moisture, during its curing process […]

The silane and silicon used in the polysulfide sealant

In this article we will learn that the silane coupling agent and silicon used in the polysulfide sealant. The polysulfide sealant has excellent oil and solvent resistance, low air permeability, good elasticity and superior mechanical properties, can achieve good bond strength to both metal and non-metal. The polysulfide sealant is an important adhesive in many […]
