SILSURF series silicone polyethers for coatings and inks

SILSURF non-ionic silicone polyethers are copolymers of polydimethylsiloxane and polyoxyalkylenes. They deliver remarkable reduction of surface tension, superior superwetting over difficult substrates, film levelling and deaeration for waterborne, solventborne and energy-curable coatings.

SILSURF A008, B608, C410 and D208 grades with tunable hydrophilic balance
Reduction of dynamic surface tension down to 20 to 22 mN per m for wetting
Elimination of craters, pinholes, orange peel and flow defects in coatings
Application across waterborne industrial finishes, printing inks and UV varnishes

SILWAX series alkylated silicones and specialty waxes

SILWAX alkyl-modified silicones unite the lubrication of polydimethylsiloxane with the organic compatibility of long-chain hydrocarbons. Ranging from fluids to high melting waxes up to 70°C, they provide dependable slip, hydrophobic repellency and broad compatibility with organic resins.

SILWAX B106, D222, J1015 and WS series with tailored alkyl chain lengths
Solubility across mineral oils, synthetic fluids and organic solvents
Formation of durable hydrophobic, anti-sticking release barrier on surfaces
Utilization in high temperature greases, polishes, mould release and hot melts

SILMER series reactive organo-functional silicones

SILMER functional monomers and oligomers feature chemically reactive epoxy, vinyl, acrylate, amine or carbinol end groups. They chemically bond into polymer networks during crosslinking, imparting enhanced thermal resistance, flexibility and moisture barrier to composites, sealants and resins.

SILMER EP epoxy silicones, ACR acrylates and NH amine functional modifiers
Covalent chemical bonding into epoxy networks, polyurethanes and acrylates
Improvement of impact toughness and thermal shock resistance in composites
Formulation components for 3D printing photopolymers and optical adhesives

SILQUAT cationic quaternary silicones and SILAMINE compounds

SILQUAT cationic silicone quaternaries and SILAMINE amino silicones exhibit strong substantivity toward negatively charged surfaces such as fibers, metals and minerals. They form a resilient antistatic layer, offering silky conditioning, reduced surface friction and lasting hydrophobic protection.

SILQUAT D208, J208 quaternary salts and SILAMINE 2972 amino polymers
Effective dissipation of static charges on synthetic polymers and films
Resistance to water wash-off through strong ionic bonding to substrates
Formulation in industrial antistatic sprays, fiber finishes and lubricants

SILUBE series silicone copolymers and invert emulsifiers

SILUBE alkyl polyether silicones are multi-functional comb copolymers engineered with both hydrophilic polyoxyethylene segments and hydrophobic alkyl and siloxane backbones. They provide outstanding stabilization of water-in-oil and invert emulsions under demanding thermal and shear stresses.

SILUBE J208-612, 316 and CS-1 versatile emulsifier copolymer chemistry
Stable formation of water-in-oil invert emulsions at temperatures up to 180°C
High resistance against high salinity, electrolytes and mechanical shear
Utilization across release lubricants, drilling fluids and specialty blends

Grade identification for Siltech Corporation organo-functional silicones

Technical selection of silicone specialties from Siltech Corporation (Siltech) requires confirmed parameters from product specifications.

Technical inquiries should identify exact product codes such as SILSTAB 2100, SILSURF A008, SILWAX B106 or reactive monomers SILMER EP alongside chemical functionality and resin matrix.

Providing manufacturer Technical Data Sheets (TDS) and Safety Data Sheets (SDS) ensures verified alignment of kinematic viscosity, active silicone content, organo-functional equivalents and solvent composition across delivery lots.

Technical selection of SILSTAB silicone surfactants for polyurethane foams

Selecting SILSTAB silicone surfactants relies on foam density, processing equipment and blowing agent chemistry.

For continuous production of rigid PIR and PUR insulating sandwich panels with hydrocarbon blowing media (pentane, cyclopentane), high efficiency stabilizers SILSTAB 2100 and 2450 provide uniform cell structure, low thermal conductivity and reliable metal facer adhesion.

In flexible slabstock polyether foams, SILSTAB 2550 delivers a broad processing latitude, preventing foam splitting and density variations.

Formulating SILSURF silicone polyethers in industrial coatings and inks

Non-ionic SILSURF polyether siloxanes are tailored to formulation polarity and surface tension requirements.

In waterborne industrial primers and wood coatings, SILSURF A008 lowers dynamic surface tension to 20–22 mN/m, securing spontaneous spreading over low-energy or oil-contaminated substrates without cratering.

In radiation-cured UV inks and screen varnishes, SILSURF D208 provides superior slip, scratch resistance and anti-blocking performance under high line speeds.

Upgrading composites and polymer resins with SILMER reactive silicones

SILMER reactive functional silicone monomers and telechelic oligomers are incorporated into polymer matrices during resin synthesis.

Epoxy-terminated SILMER EP grades chemically crosslink into thermoset epoxy networks, markedly enhancing Charpy impact toughness, thermal cycling resistance and flexibility.

Acrylate-functional SILMER ACR oligomers provide weatherability and moisture repellency in stereolithography (SLA) 3D printing photopolymers and optical electronic encapsulants.

Industrial release and invert emulsions with SILWAX and SILUBE copolymers

Alkyl-modified silicones SILWAX and comb copolymers SILUBE serve in demanding release coatings, metalworking lubricants and specialty emulsions.

Featuring long organic alkyl chains, SILWAX compounds offer complete solubility in mineral and synthetic hydrocarbon oils, forming a resilient friction-reducing barrier.

SILUBE copolymers provide robust emulsification for stable water-in-oil invert emulsions resistant to shear and thermal degradation at temperatures up to 180 degrees Celsius.
