Sikaflex®-11 FC is a one-component, gun-grade, adhesive and sealing compound of permanent elasticity. This dual-purpose material is based on a special moisture-cured polyurethane with an accelerated curing time that meets ASTM C920 Type S, Grade NS, Class 12.5 for internal and external applications.
BENEFITS
Excellent adhesion to all cement-based materials, brick, ceramics, glass, metals, wood, epoxy, polyester and acrylic resin.
Fast cure rate.
Good weathering and water resistance.
Can be over painted with water, oil, and rubber-based paints. (Preliminary tests recommended).
High durability and ageing resistance.

Wood.
PREPERATION
All surfaces must be structurally sound, clean, dry and free from grease, oil, wax, dust and surface contaminats such as curing compounds, release agents, coatings and friable material. Sikaflex®-11FC adheres without primers and/or activators. However, for optimum adhesion and critical, high performance applications, such as on multi story buildings, highly stressed joints, extreme weather exposure or water immersion, the following priming/or pre treatment procedures shall be followed.
Non-porous substrates: Aluminium, anodised aluminium, stainless steel, PVC, galvanised steel, powder coated metals or glazed tiles; slightly roughen surface with a fine abrasive pad. Clean and pre-treat using Sika® Aktivator- 205 applied with a clean cloth. Before bonding / sealing, allow a waiting time of > 15 minutes (< 6 hours).
Porous substrates: Concrete, aerated concrete and cement based renders, mortars and bricks, prime surface using Sika® Primer-3 N applied by brush. Before bonding / sealing, allow a waiting time of > 30 minutes (< 8 hours).
CLEANING OF EQUIPMENT
Clean all tools and application equipment immediately after use with Sika® Remover-208 and / or Sika® Colma Cleaner.
Once cured, hardened material can only be removed mechanically. For cleaning skin use Sika® Hand Wipes.
