CAF · Elkem Silicones ·

ELKEM CAF 7037 MF is a low-viscosity, neutral-curing 1K silicone sealant (oxime, MEKO-free, brick red) for coating and separation applications.

The Elkem CAF range comprises one-component (1K), neutral (oxime) curing silicone sealants — low-odor, non-corrosive, with excellent dielectric properties. CAF 7037 MF is tailored to specific industrial applications — the most important properties and areas of application are listed below.

MEKO-free, low viscosity

CAF 7037 MF combines neutral crosslinking (oxime) with a low viscosity of 50,000 mPa·s — flows well into complex geometries, is non-corrosive and MEKO-free. Proven for the continuous coating of conveyor belts and electric motor insulation.

What distinguishes the CAF 7037 MF

Oxime crosslinking, MEKO-free
Neutral 1K crosslinking without MEKO — low odor, REACH compliant and non-corrosive.
Low viscosity
50,000 mPa·s — flows into complex geometries, ideal for coatings and immersion processes.
Long potting time
Skin formation 25–30 min — allows for careful processing even of large areas.
High separation efficiency
High Release — weakens adhesion to subsequent materials, ideal as a release film.
Excellent thermal aging
Continuous +225 °C, peaks +250 °C — proven in engine insulation.
Good dielectric properties
19 kV/mm dielectric strength — for electric motors and coil insulation.

What is the CAF 7037 MF used for?

Conveyor belt coating
Continuous non-stick coating of industrial conveyor belts.
Electric motor insulation
Impregnation and insulation of windings and coils in electric motors.
iron soleplates

Air filter bonding
Sealing of air filters in industrial and automotive applications.
Screen-printed seals
Seals applied using the screen printing process ("Silk Screening").
Release film applications
Non-stick separating layer for subsequent coatings or bonding.

processing

1
Prepare the substrate
Bonding surfaces must be clean, grease-free, and dry. Oxime crosslinking is non-corrosive and safe for use on copper and non-ferrous metals.
2
Apply
Apply an even bead or drops from tube/cartridge/container — skin formation typically takes 7–30 min.
3
Joining / Smoothing
Position joining surfaces or smooth them with a spatula within the skin formation time.
4
Curing
Cross-linking through humidity — standard 24–72 h for full curing. Low odor in the workplace.
5
Security
Observe SDS guidelines — ventilate during processing, wear gloves.

Important instructions

Substrate preparation
Prepare bonding surfaces to be clean, grease-free, and dry. Adhesion is not possible on PE, PP, PTFE, and silicone oils. Conduct a preliminary test for critical material pairings.
Storage & Handling
Store in the unopened original container at 5 to 30 °C in a dry place, protected from sunlight. Consult the current SDS before opening.
Corrosion warning (Acetic)
Acetic crosslinking can attack copper, zinc, and galvanized steels. For corrosion-sensitive metals, choose the neutral variant (CAF 530, CAF 731, or CAF 730).
Application advice
SILITECH will advise you on the optimal CAF variant for your application — substrate pairing, corrosion and temperature requirements, desired appearance and processing workflow.

Frequently asked questions about CAF 7037 MF

Practical application and design questions — answered by SILITECH.

ELKEM CAF 7037 MF: Low-viscosity, neutral-curing, one-component silicone sealant (oxime, MEKO-free, brick red) for coating and separation applications. Main applications include conveyor belt coating, electric motor insulation, and iron soleplates.

Oxime crosslinking is a neutral, one-component crosslinking chemistry that crosslinks through atmospheric moisture and releases only small amounts of oxime. Advantages include low odor in the workplace, non-corrosive to metals, excellent dielectric properties, and thermal stability—making it ideal for use in aerospace maintenance and electronic bonding with corrosion-sensitive components. CAF 7037 MF is also MEKO-free (methyl ethyl ketoxime-free) and therefore REACH compliant without MEKO labeling.

CAF 7037 MF adheres without primer to glass, ceramics, many metals (stainless steel, aluminum, copper in neutral variants), and numerous engineering plastics. Adhesion is not possible to PE, PP, PTFE, and silicone oils—these substrates are fundamentally incompatible with silicone. If in doubt, we recommend a preliminary test or consulting SILITECH regarding the specific material pairing.

Prepare the substrate to be clean, grease-free, and dry. Apply the sealant evenly from the cartridge or container—refer to the TDS for skin formation and curing times. Store in the unopened original container at 5 to 30 °C, protected from sunlight. Use opened containers promptly—for Acetic systems, reseal tightly immediately after opening. Consult the current Safety Data Sheet (SDS) before use.

In the comparison table above, you will find related CAF products with adapted properties—different color, different crosslinking system (acetic vs. neutral), or different mechanical properties. If you are unsure about the optimal choice, we would be happy to advise you—contact SILITECH with your requirements (substrate pairing, temperature, corrosion requirements, appearance).
