DESCRIPTION
BIO-FIX PLUS is based on a unique blend of liquid epoxy polymer and aliphatic polyamine curing agents which is able to displace water from wet surfaces in order to make a permanent bond. The formulation is solvent-free to ensure safety and maximum technical performance. *Kevlar¨ fibres are incorporated for reinforcement and viscosity management to achieve high application rates and excellent film build - even underwater!

BIO-FIX PLUS provides permanent protection even under the most adverse conditions. When manufactured for Nuclear service it is qualified for Service Level 1 use with above or below water application. The formula is uniquely field-friendly and uses advanced low toxicity ingredients.

*Trademark E.I. DuPont de Nemours Co.

SURFACE PREPARATION
Underwater Remove marine biological settlement and corrosion by high pressure water jetting or similar methods with or without abrasive injection. Conventional air/abrasive blasting works well at shallow depths however efficiency falls off sharply below about 10 ft. Hand held power tools such as grinders or needle guns will give good results if applied conscientiously in small areas but will be inadequate in large areas. Plan to apply the BIO-FIX PLUS within 30 - 45 minutes of surface preparation to minimise rerusting or initial settlement of fouling which can interfere with initial adhesion. Conventional abrasive blasting using air abrasive or centrifugal blasters are preferred methods of surface preparation in most cases where oily or greasy contamination is not a problem.

Above water Preparation requires similar high pressure water blasting or dry abrasive blasting to yield a firm, granular surface free of loose contamination.

APPLICATION
BIO-FIX PLUS is supplied in two gallon (7.6 litres) kits of one gallon (3.8 litre) each of epoxy and curing agent. Whenever possible these components are made in contrasting colours for example yellow base plus black curing agent to yield an olive green mixture. This system allows the mixers to see at a glance if "hotspots" of unmixed epoxy base or curing agent which will never cure are still present. Remove equal quantities of base and curing agent from their cans and place them side by side on a flat sheet of plastic, fibreboard, etc. Mixing is easily accomplished by folding the components into each other using a spatula or piece of wood. Once mixing begins there will be about 40 minutes of working time available at 80 degrees F (27 degrees C). This time can be extended by keeping the components and mixture cool. Send mixed material underwater as soon as possible rather than leaving it on a hot deck.

Underwater Take the mixed BIO-FIX PLUS underwater in a can or bucket, it will be helpful to have some method of holding the container such as a hook or magnet on the structure especially if visibility is poor and a lantern must also be carried. Applicators such as broad putty knives or plastic straight edged glue spreaders work well on most surfaces. Painters mitts will work well on small diameter tubular sections such as risers. BIO-FIX PLUS is resistant to the effects of wave application during curing and will be found to be easier to apply than traditional 'splash zone' compositions and much less messy than lower viscosity underwater 'paints'. BIO-FIX PLUS has a strong tendency to stick to underwater surfaces and expensive equipment should be protected using plastic suits or sacks to cover exposed surfaces.

Above water Apply using an appropriate tool such as a spreader or short, stiff brush if the surface is especially rough.

TEMPERATURE
BIO-FIX PLUS may be applied in temperatures as low as 45 degrees (7 degrees C) -curing will be slow, however the viscosity of the material will still be workable. Temperature will exert a considerable influence on the rate of curing of chemically cured coatings such as BIO-FIX PLUS. In broad terms expect each 10 degrees C, (18 degrees F), rise or fall in temperature to half or double dry times and pot lives.
