promoters, surface modifiers, hydrophobing agents, silane crosslinking agents,
resin additives, curing agents, surface protective agents, dispersing agents,
terminating agents, pharmaceutical intermediates, silylation reagents,
allylation agents, electron donors, finishing agents, softening agents, paint
additives, coating auxiliaries, plastic additives, water scavengers and
cosmetics additives.



Adhesives & Sealants
Co-Formula silane coupling agents are mainly used in adhesives and sealants as
coupling agents, tackifiers, surface modifiers, crosslinking agents, water
scavengers and terminating agents, which can bring the following
characteristics:

Reduce viscosity, improve dispersion and processability of inorganic fillers
Improve adhesion and compatibility between organic resins and inorganic
substrates
Increase dry and wet strength and bond durability of substrates
Prevent premature rubber vulcanization and improve product storage stability
Increase the uniformity of vulcanization
Increase elongation at break


Amino, epoxy and mercapto functional silanes can be applied to most resin
systems. With their presence, excellent bonding can be formed on metals, glass
and resins. These silanes are the most commonly used coupling agents for the
condensation silicone sealants and adhesives.



Most silane coupling agents can be used for the surface treatment of inorganic
fillers. Co-Formula also provides dispersing agent for various fillers and
pigments. Inorganic fillers and pigments treated by Co-Formula products have
better dispersibility in adhesives and sealant system.



Paints & Coatings
Co-Formula silane are playing the following roles in paints and coatings.

Improve adhesion of organic polymers on inorganic substrates
Improve water resistance, weatherability and abrasion resistance of coatings
and substrates
Improve compatibility and dispersion of organic resins and inorganic pigments
and fillers
Improve cross-linking properties of resin systems
Improve the hardness of coating surface


Co-Formula silane coupling agents can be used as primers and tackifiers in
coating industry. The main function of the primer is to increase the bond
between the resin coating and the protected substrate. The main component of
the primer is silane coupling agent, which can be combined with a certain film
forming agent, catalyst and pigments. The bottom coating is made by solvent
dilution, which is formed by solvent evaporation and hydrolysis and
condensation of water in the air. Silane coupling agent should be decided
according to the type of resin and the type of protected substrate.



Wires, Cables & Pipes
Silane coupling agent is mainly used as crosslinking agent and tackifier in
wires, cables and pipes, which endows the materials with the following
properties:

Enhance thermal deformation stability and mechanical strength of modified
materials
Improve wet electrical properties of modified materials
Improve chemical resistance of modified materials
Increase filler addition and improving processability


Different silane coupling agent can be applied according to the material and
requirement of modified cable system. The cable materials suitable for
modification with silane coupling agents are mainly polyolefin and elastomer
polymers.



Vinyl silanes are the most commonly used crosslinking agents for polyolefin
materials, because they can be grafted with polyolefin or copolymerized with
olefin at higher temperature and initiator action. The alkoxy functional groups
on silanes can undergo intermolecular condensation reaction after hydrolysis in
wet environment and polyolefin crosslinking.



Chemical Synthesis


Co-Formula provides a series of chloro silanes and silane intermediates which
can be used for the synthesis of a wide variety of silane coupling agents,
silicone fluids, silicone resins, silicone rubbers and other chemical
compounds. These functional silanes normally serve as basic materials,
silylation reagents, allylation reagents, electronic donors or terminating
agents. These offerings have gained great reputation in the market of chemical
synthesis.
