SP 115 is available here in South Africa. $45 for 1kg and a mixing ratio of 5:2 gives a 30 hardening time. SP 115 is a low viscosity, ultra-clear epoxy laminating system. It has been designed for the manufacture of laminates such as those used in sail and surfboards which are to remain unpainted, and where a very clear finish is required. In this way colourful embedded graphics and attractive fabric weave styles can be kept visible. The material also contains UV filters which give the product its characteristic transparent pale violet/blue colour. These filters both enhance the sharpness of graphics, and, when overcoated with a suitable UV-screening PU varnish, will reduce the tendency of clear laminates to yellow after prolonged exposure to sunlight. The product is particularly suitable for use with glass fibre reinforcements which use fibre sizings optimised for wet-out and laminate clarity, such as RE210D.
It has a 2 year shelf life (unmixed :-) )
