Anti-corrosion primer withstands high temperatures
A new styrene acrylic copolymer primer, designed for use in high performance anti-corrosion applications, has been introduced by Scott Bader Company
It was primarily developed as a vacuum injection resin, but is equally suited to other similar production techniques.
With excellent mechanical properties and impact resistance, the product is ideal for manufacture of large structures.
Forty two tons of the resin have been supplied via Scott Bader Scandinavia AB for the production of 33 pipeline covers.
These have a 70% glass content and represent a combined weight of 140 tons.
The size of the structures is equally impressive, with the largest cover having dimensions of 14m x 12m x 4m high.
An infusion production process has been used to pull resin under vacuum through the reinforcement to fully wet-out the glass fibre layers.
Polyester beams are used to fix the covers to the seabed on each side of the pipework run.
The outer surfaces of the covers are finished with Scott Bader gel/topcoat in a RAL 1004 (yellow) colour.
The smooth moulded outer shape of the covers provide excellent protection to pipework, eliminating snagging points and giving a degree of impact protection.
The yellow top coat provides good identification and visibility in undersea conditions.
