What Are Water Repellents?


Water repellents are chemicals that prevent water from penetrating surfaces. They work by increasing the surface tension of water, causing it to form droplets and slide off the surface.

Characteristics of Water Repellents

  • Increased Surface Tension: They increase the surface tension of water.
  • Prevention of Water Penetration: They prevent water from penetrating surfaces.
  • Protection Against Other Liquids: They can also prevent other liquids like oils and dirt from penetrating surfaces.
  • Droplet Formation and Sliding: They cause water droplets to form and slide off the surface.
  • Longer Dryness: They help surfaces stay dry for a longer period.
  • Penetration of Porous Materials: They penetrate porous materials to prevent water from getting inside.
  • Formulation and Concentration: They can be produced in various chemical formulations and concentrations.

Applications of Water Repellents

  • Construction: Used to protect walls, roofs, foundations, and other building materials from water.
  • Textiles: Used to protect fabrics from water and oil.
  • Leather: Used to protect leather products from water and dirt.
  • Automotive: Used to protect vehicle bodies from water and snow.
  • Glass: Used to protect glass surfaces from water and dirt.
  • Wood: Used to protect wooden products from water and decay.
  • Electronics: Used to protect electronic devices from water and moisture.

SILMASTAB AX2244


SILMASTAB AX2244 is a multifunctional additive for PE/EVA HFFR cable compounds, cable production, and various filled compounds including glass fiber, talc, other silicates, and wood. It helps prevent color fading of cables due to the use of natural MDH/ATH, eliminates corrugated surface issues, reduces viscosity and torque during the extrusion process, improves the distribution of fillers and mechanical properties, and provides excellent hydrophobicity and reduced water absorption. 

It is commonly used to pass thermal aging tests under water conditions and enhance adhesion between plastic and metal substrates.
