Jotun Paints, Sandefjord, Norway, has announced a range of new marine antifouling products. SeaAlu, is a product for use on aluminium hulls and is intended to replace Jotun's Alusea Classic and Alusea Turbo, which have been removed from sale as a consequence of the IMO Antifouling Systems Convention's ban on TBT containing products.

According to Jotun, SeaAlu is a copper-oxide – and TBT – free self-polishing system which can be used in all sea temperatures and is effective at speeds up to 40 knots. Although the new product can be used to overcoat existing AluSea products without a sealer coat, it is advisable according to Jotun to apply a sealer to prevent possible polishing-through to expose the TBT-antifouling layer below.

SeaOmega is designed for antifouling protection for vessels trading in cold waters. According to Jotun, low seawater temperatures combined with variations in sunlight, require a carefully formulated TBT-free self polishing antifouling to ensure release of the active substance at the optimum rate.

Jotun states that this new product is based on its innovative TBT-free technology which ensures freedom from fouling and leached layers and the maintenance of a constant rate of polishing.

SeaQuantum LLL is the latest addition to Jotun's SeaQuantum range of antifouling products. According to Jotun, it is a hydrolysing silyl antifouling and shares most of the advantageous features of the existing range, including an excellent and predictable antifouling performance up to 60 months together with self polishing characteristics without the build-up of a leached layer. However, the hull smoothing effect has been given less focus than in the other SeaQuantum products, because according to Jotun, the advantages of hull smoothing are much reduced for vessels approaching full refurbishment, vessels with shorter trading routes at low speed and vessels that suffer mechanical damage during trading. SeaQuantum LLL has higher volume solids and requires a lower dry film thickness than other members of the range, which leads to a more economical solution for these vessels, according to Jotun.
