Sika® Silbridge-300

Extruded, ultra low modulus, elastomeric silicone profile

Sika® Silbridge-300 is an extruded, ultra low modulus, elastomeric silicone profile that is usually bonded to substrates using Sikasil® WS-295 sealant as an adhesive. Sika® Silbridge-300 comes in a variety of standard shapes, colors and sizes and is successfully used in various applications.

  • High tear resistance
  • Ease of installation
  • Color fast formulation
  • Wide operational temperature range
  • Non corrosive and corrosion resistant
  • Resistant to ultraviolet exposure and weathering
  • Capable of sealing high movement joints
  • Reduces stress at bond-line making it well suited for soft and sensitive substrates such as EIFS
  • Rapid cure of thin adhesive layer allows for early movement of substrates
  • Economical alternative to cutting out existing failed sealant
  • Unaffected by Ozone
  • Unaffected by Radiation

Application

Application steps

SUBSTRATE PREPARATION

Porous surfaces should be cleaned with dry, oil free compressed air. Grinding or abrasion may be necessary to remove materials that may interfere with the sealant adhesive. If the substrate is cleaned with pressurized water, use caution to prevent water from entering the structure through the open joint. Ensure that all cleaning agents are completely removed and allow the substrate to adequately dry before applying the Sikasil WS-295 and the Sika® Silbridge-300 profile. Make sure to follow sealant adhesion guidelines of Sikasil WS-295 product data sheet. Non porous surfaces should be cleaned with an appropriate solvent using the two-cloth method.

CLEANING OF TOOLS

Clean Up

Uncured material can be removed with approved solvent. Cured material can only be removed mechanically. For spillage, collect, absorb, and dispose of in accordance with current, applicable local, state, and federal regulations.
