<strong>Technology</strong>/Method Spray - On Lining/Polyurethane<br />
I. <strong>Technology</strong> Background<br />
Status Conventional<br />
Date <strong>of</strong> Introduction Formally known as Copon Hycote 169HB by E.Wood Inc. A preceding product<br />
Copon Hycote 169 was introduced in the UK in 1999. A succeeding product 3M<br />
Scotchkote Spray-in-Place Pipe 269 (which is a polyurea <strong>for</strong>mulation) is slated<br />
<strong>for</strong> introduction in the US in 2009.<br />
Utilization Rates Actively being used in UK and Canada. About 200 miles have been lined, the<br />
bulk <strong>of</strong> which is in UK.<br />

Copon Hycote 169HB is a two component coating specifically designed <strong>for</strong> use<br />
in pipeline applications and is available as a grey finish. The material has a low<br />
viscosity to allow <strong>for</strong> pumping to remote spray heads and is moisture tolerant to<br />
provide high-build slump resistant coatings with improved adhesion<br />
characteristics. Finished coatings are hard, glossy and free <strong>of</strong> surface tack or<br />
greasiness. This rapid setting polymeric lining <strong>of</strong>fers a semi-structural spray<br />
lining alternative to conventional replacement technologies without the large<br />
scale disruption generally associated with replacement.<br />
<strong>Main</strong> Benefits Claimed • No large scale disruption compared to PE slip lining<br />
• Excellent abrasion resistance.<br />
• Long-term corrosion protection material<br />
• Equivalent to AWWA M28 Class 3 <strong>Rehabilitation</strong> technology.<br />
• Usually bypass service is not required.<br />
• Approved under UK Regulation 31(4)(a) <strong>of</strong> the Water Supply (Water<br />
Quality) Regulations.<br />
• Recommended <strong>for</strong> pipes prone to local damage and well suited <strong>for</strong> local<br />
host pipe damage.<br />
• Easier leakage detection on metal pipes.<br />
<strong>Main</strong> Limitations Cited • Not recommended <strong>for</strong> pipe with residual asset life less than 30 years<br />
• Not recommended <strong>for</strong> use in PVC pipe because <strong>of</strong> failure pattern in host<br />
