Processing is particularly easy because the product is delivered ready to use. Application can either be carried out manually or using robotized application equipment.

The bead of CAF 50 is applied on one of the two joint surfaces. Assembly must take place before the product has formed a skin.

It is recommended not to exert any strain on the assembly straight away.


Curing of CAF 50 starts as soon as the product comes into contact with atmospheric humidity.

Skin formation time *, min......................................................15

Cured thickness after 16 h*, mm...........................................2

Cured thickness after 24 h*, mm...........................................2.5

* Temperature 23 °C, relative humidity 50 %

The curing rate increases with both temperature and hygrometry.

Comment: it is recommended to apply the product to clean and dry surfaces.

CAF 50 BLACK may be stored at temperatures between 2°C / 36°F and 30°C / 86°F for up to 6 months from its date of manufacturing.Please consult the Safety Data Sheet of this product.


CAF 50 is a one component silicone elastomer which cures at room temperature:

  • BLACK (standard color)

It has a chemically neutral curing system, guaranteeing no oxidation on contact with metals.

Odorless, it is particularly well accepted around the workstation environment.

CAF 50 has a skin formation time that is suited to industrial constraints allowing great flexibility in processing.

It has high mechanical properties as well as remarkable performance levels in terms of:

  • resistance to engine and gearbox fluids
  • adhesion to metals and plastics



1 Part RTV Alcoxy

  • Chemically neutral.
  • Odorless.
  • Outstanding adhesion to many surfaces.
  • Resistance to engine lubricants.
  • High continuous heat stability (– 60 to + 185 °C).
  • High extrusion properties.


CAF 50 has been specially developed for professional customers. It is well suited to requirements in terms of performance and cost effectiveness in sealing and bonding using wet gasketing techniques in the automotive sector (drive train, etc.), in the domestic appliance sector, for electrical and electronic applications …

Automotive and vehicles in general

CAF 50 is the ideal elastomer for bonding and/or gasketing between materials of different types.

  • Sealing of housings and covers on engines.
  • Sealing of water pump, oil filter and air filter casings.
  • Bonding of main headlight and auxiliary light lenses.
  • Inlet collectors.
  • Air conditioning systems.
  • Gearboxes...
  • Sealing/bonding of electrical and electronic parts.
  • Sealing/bonding applications having to withstand a marine environment.

Domestic appliances

The characteristics and performance levels of CAF 50 make it ideally suited to many bonding and sealing applications for domestic appliance components:

  • Bonding of iron water containers.
  • Bonding of microwave oven components.
  • Bonding of ceramic cooking hob components, ovens, cooker fascias.
  • Many different bonding applications for small domestic appliances...

Electrical and electronics

Its chemical neutrality and bonding under conditions of humid heat make CAF 50 the ideal protective product, providing long lasting protection at continuous temperatures up to 185 °C.

General industry 

CAF 50 provides perfect flexible sealing and bonding in many industrial areas: original equipment, maintenance, servicing, repair.
