The Core
A core determines the line's tensile strength, stretch,
and stiffness. Altering one affects the other two.
Scientific Anglers™ has
pioneered the advances in core design. We use braided monofilament,
braided multifilament, or single strand monofilament cores, depending
upon the application.
Some fly line manufacturers
have stopped offering braided cores because of the complex design. Our
proprietary processes, however, allow us to achieve the optimal balance
of properties for the industry's most-trusted performance.
The Coating
At Scientific Anglers,™ how we formulate and apply the
coating to the core sets us apart. With our unique experience and
processes we are able to make each line with the optimal casting weight
needed to load the fly rod and set higher standards in maintenance-free
excellence in every area of fly line performance.
Slickness
- Our unique combination of polymers and plasticizers, together with the
revolutionary 'dry-slickness' of AST, results in an inherent stiffness
and permanent slickness unsurpassed in fly fishing. It's also the reason
you can cast our lines with less effort over short and long distances.
Floatation
-The density of the coating helps determine whether the line will float
or sink. Our floating lines feature 3M's Microballoons™ and hydrophobic
agents to repel water and increase floatation, further enhanced by
optimal air entrapment inside the core. AST provides yet another level
of floatation.
Sink Rates
- Our sinking-line formulations achieve sink rates from 1.25" to 10.0"
per second to give you more choices for more conditions. In our
faster-sinking line coating we use powdered tungsten because it is
denser and safer than lead. In our slow-sinking lines we use
high-density glass beads.
Durability
- Our exclusive methods of combining polymers and plasticizers create a
combination that stabilizes the coating and prevents premature
brittleness. Advanced ultraviolet inhibitors retard the effects of
sunlight and make Scientific Anglers™ fly lines more resistant to wear
and tear.
Formulating the Perfect Line
3M Microballoons™ are added to the coating of our
floating lines to give us precise control over line density: The more
Microballoons we add, the lower the line's density and the higher it
floats. Glass beads are used to control the rate of slower-sinking
lines, while powdered tungsten, the most effective sinking line coating
additive in fly fishing, allows us to create faster-sinking lines that
are safer than those containing lead for fish, birds, people, and the
entire environment. We also use AST in Ultra 4 floating and sinking-tip
lines, which keeps line clean for enhanced floatation.
