Application of sealing products for different engine parts

ПодписатьAjusa:

AJUSA distributes its own line of AJUSIL sealant. In this post, we explain the characteristics of these components and their main uses.

 

Silicone sealant is a component that replaces or complements certain gaskets that can be found in an engine. The purpose of its use is the same as that of the gaskets: create and maintain a sealing of liquids or gases between two separable surfaces. If these two surfaces were perfectly rigid, parallel and the bolts could be tightened at the same time, they would be sealed without needing a gasket. 

Ajusa, following its path to offer full coverage of auxiliaries to repair your engine, launched the silicone sealant AJUSIL in 2009. It is presented in 75 ml or 200 ml containers.



Application of sealing products 

The first and most important thing is that there is no rule that states on what parts of the engine or on what part of a gasket you can apply a gasket maker. At the time of performing an action on an engine, it is always advisable to work with the engine manufacturer specifications

There are some parts of an engine where the tendency is to eliminate the traditional gasket and apply gasket makers existing in the market. In the case of automotive components, the product must have certain features able to withstand the high demands of an engine (temperature, pressure, chemical agents, etc.) and with the necessary quantity on the required area.

Parts of engines and sealing gaskets where engine manufacturers recommend to apply a sealing product to complement and secure sealing on these areas:

 

  • The sealing on an engine component in contact with two different pieces. Intersection of the vacuum pump.
  • Junction of two different parts when a liquid flows between them. Junction between water pump and lateral side of the block, thermostatic box, junction of the crankcase with the bottom side of the block, etc.
  • Junction of engine parts on different planes creates critical areas where a gasket maker is often applied. The valve cover that closes over the camshaft cap, the closing cover over the seal, etc.

 

In these cases, the silicone sealant replaces the motor seal or complements it. Ajusil satisfies the highest exigencies concerning reliability, thermal resistance, resistance to fluids and practical use. 

  

AJUSIL Characteristics  

Gasket maker Ajusil has a base of based silicone elastomer and neutral low odor. One component, does not lack premix, excellent temperature resistance and excellent adhesión are other characteristics. Besides, no endurance nor or cracks. 

For your application, surfaces must be clean and dry. If necessary and a mechanical treatment should perform cleaning the surface with an oil-solvent such as acetone. Once the product is applied, it begins to reticulate or to harden from the within 10 or 15 minutes, arriving reaching at the total lattice at approximately 18 hours. 

Ajusil cleaning is simple. You only need a product with an organic solvent. Store in a cool and dry place.
