SP 106 is a simple to use, all-purpose epoxy which can be used for gluing, coating, laminating and filling. With its
range of hardeners, and easy 5:1 mix ratio by volume, SP 106 provides a quick and convenient way of using one
epoxy system for a very wide range of tasks. SP 106 has been established for over 20 years as the primary epoxy
system for the manufacture and repair of wooden boats, and it is now widely used in many other woodworking
applications from cabinet making to the manufacture of large wooden moulds. With its Extra Slow Hardener SP 106
can be used for jobs requiring a long working time, or in ‘tropical’ conditions of high ambient temperatures.
In its unmodified form, SP 106 can be used as a clear coating for wood and other substrates, or for laminating
lightweight glassfibre fabrics such as those used for reinforcing joints. When used for clear coating, cured SP 106
should be overcoated with a UV-resistant varnish.
INSTRUCTIONS FOR USE
SP 106 should be used at between 15°C-25°C. At lower
temperatures the product thickens and therefore it is necessary
to prewarm resin, hardener and surfaces to be bonded or
coated before use. At higher temperatures and larger volumes
the pot life of the mixed resin/hardener is reduced.
MIXING AND HANDLING
Use either Fast, Slow or Extra Slow hardener, depending on the
speed of reaction and working time required, in the ratio:
SP 106 resin : SP 106 hardener
5 : 1 (by volume)
100 : 18 (by weight)
Mix as accurately as possible since varying the amount of
hardener will not change the cure speed significantly but will
greatly reduce the cured strength and water resistance
properties of the material.
If using the Gurit pump dispensing system ensure that the
pumps are fitted and used according to the pump pack
instructions. Pumps should also be regularly checked and
cleaned to ensure that they continue to dispense the correct
Solvent-free epoxies have limited pot life. Mix sufficient only for
immediate use to avoid excessive heat build up and resin
wastage through early gelation: with fast hardener mix no more
than can be used in 5-10 minutes; with slow and extra slow
hardener mix no more than can be used in 15 – 20 minutes.
MIXING RESIN & HARDENER
The SP 106 resin and hardener should be mixed thoroughly
together for at least one minute. To maximise the working life,
use from the pot quickly or transfer to a shallow tray to help
dissipate the heat of the reaction. See table on “Working
Before using the product ensure that surfaces to be bonded,
coated or filled are clean, dry and dust-free. All surfaces should
be prepared by abrading with medium grit paper, the dust
removed then wiped with Gurit Fast Epoxy Solvent (Solvent A)
for maximum adhesion.
