Silicoflex Primer

Home»Expansion Joints»Silicoflex Primer

The Silicoflex System consists of an inverted ‘V’ shaped, preformed, extruded silicone rubber seal, with a single component silicone locking adhesive and a primer.  The primer consists of 2 parts:

Features

Low Stress Design

During normal cyclic movement, the Silicoflex seal is not in tension due to its folded inverted “V” shape.  This reduces stress on both the seal and the adhesive and eliminates the possibility of cohesive failure typically found in field molded sealants.

Large Movement Range

Silicoflex is manufactured in three different sizes which cover the full range of movements typical of single cell joint openings.

Temperature Insensitive

Silicoflex will remain flexible in almost any environment.  The material stability temperature range for Silicoflex is -60° F to +350° F.

Ultraviolet Radiation and Ozone Resistant

The Silicoflex seal is comprised of an inorganic base silicone, which means it is highly resistant to the damaging effects of ultraviolet radiation and ozone attack.  This resistance is far superior to organic rubbers commonly found in other joint sealing systems which degrade due to U.V. exposure.

Versatile

Silicoflex will bond equally well to steel, concrete and elastomeric or polymer concrete surfaces.  Silicoflex can also be used to reseal failed strip seal joints and works well with irregular, tapered and spalled joint openings.  These features make Silicoflex ideal for maintenance and retrofit projects.

Durable

Silicoflex applications installed in the mid-1990’s are still performing effectively to this day.

Fast and Simple Installation

After sandblasting (if necessary) and priming, installation time is about 15-20 minutes per lane.  30 – 60 minutes after the installation is complete, the lane can be reopened to traffic.

Maintenance Friendly

In the event of a puncture, Silicoflex can be easily repaired using the silicone based locking adhesive.  With more severe damage, locally damaged pieces can be removed and new pieces can be spliced in.

Debris Friendly, Self Cleaning Design

The inverted “V” shape directs debris to the edges of the seal where it is bonded and fixed.  During cycling, debris is channeled upwards thereby reducing the chance of punctures.  Other systems with “V” shaped seals direct debris towards the unsupported center, making it much more susceptible to punctures from debris.

Field Spliceable and Directional Changes

If required, the Silicoflex gland can be bonded to itself by using the same silicone locking adhesive.  This permits installations lane by lane or rapid custom tailoring of the gland to go up and around curbs and parapets.
