Isocyanate Silanes

Isocyanate is a functional group with the general formula of R-N=C=O. The isocyanate functionality has typical reactivities of alkyl isocyanates. Co-Formula isocyanate silanes are compounds which combine the functionality of an isocyanate group and an alkoxy group. These silanes can easily react with active hydrogen in organic polymers. Alkoxy groups of isocyanate silane can hydrolyze to form a reactive silanol group and offer excellent adhesion to a variety of inorganic substrates.

Production Status of Isocyanate Silanes/NCO Silanes

Co-Formula is a leading supplier of isocyanate silanes in China, with capacity of around 80 metric tons per month. CFS-006, 3-Isocyanatopropyltrimethoxysilane and CFS-885, 3-Isocyanatopropyltriethoxysilane are commercial products under regular production. Purity grade of CFS-006 & CFS-885 can be above 98%. The two items are the most used isocyanate silanes in current market. Considering the low consumption, other isocyanate silanes are made to order or in the pilot lab only.

Functions & Applications of Isocyanate Silanes

Co-Formula isocyanate silanes mainly act as adhesion promoters in paints and coatings, adhesives and sealants industries. They can improve adhesion to organic materials and improve hydrophobicity.

Isocyanate silanes can also be put into use in one-component moisture curable polyurethanes and two-component reactive urethane coatings. In addition to above applications, Co-Formula isocyanate silanes can perform excellently as crosslinkers for urethane sealants and coatings.

The largest consumption of Co-Formula isocyanate silanes comes from silyl modified polyurethane polymers (known as SPUR polymers). These silanes act as cross-linking agents for polyurethane polymers.

Besides the application in the SPUR polymers, Co-Formula isocyanate silanes are also applied as modifiers of other polymers, which can be described as silane modified polymers (SMP) or MS polymers. SPUR polymers and MS polymers have lots of similarities and common features. Both polymers are mainly used to produce sealants in construction and building industries. Sealant formulations containing isocyanate groups can make the polymers modification more smoothly, with the capacity of improving mechanical and chemical properties of various composite materials.

Epoxy silanes are bifunctional organosilanes whose molecules consists of a reactive epoxy group and a hydrolysable alkoxy group. As the main series of silane coupling agents, epoxy silanes have the same capabilities to promote adhesion between organic polymers and inorganic materials. Suitable organic polymers include epoxy, urethane, acrylic, silicone and polysulfide resins. Suitable inorganic materials include glass, metals, dyes, fillers and minerals.

Key Features of Epoxy Silanes

Particularly, epoxy silanes possess a unique property, that is, non-yellowing adhesion. Compared with other functional silanes, for example, amino silanes, epoxy silanes are more stable and won't affect the color of the finished goods. This unique property allows epoxy silanes to be a more suitable epoxy silane adhesion promoter in various coating, sealants and adhesives fields.

Development Status of Epoxy Silanes

At Co-Formula, there are a lots of epoxy functional silanes available, not only commercial ones, but also silanes with special structures.

Functions & Applications of Epoxy Silanes

Co-Formula epoxy silanes are mainly used as adhesion promoters in coatings, adhesives and sealants industry, where they can promote adhesion, improve inorganic filler dispersion, and especially, enhance anti-corrosive properties. Therefore, for epoxy silanes, marine coating is one of the most essential application fields.

In addition to general-purpose applications in solvent-based resins system, epoxy silanes can also be used in waterborne system. Waterborne coatings are much eco-friendlier than solvent-based coatings. It’s expected that market share of waterborne coatings will be expanded in near future.

More and more customers or end-users from semi-conductors and electricity industries purchase Co-Formula epoxy silanes. Their main end applications are for electronic packaging and electronic encapsulation. These epoxy silanes can improve electrical properties significantly in epoxy-based packaging and encapsulation compounds.
