SP 115 CLEAR EPOXY LAMINATING SYSTEM ¬ Excellent clarity ¬ Good ultra-violet resistance ¬ Rapid fibre wet-out INTRODUCTION 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. SP 115 also exhibits a high degree of toughness and water resistance, enhancing the strength and damage tolerance of the thin laminates typically used in sail and surfboard manufacture. Being completely solvent and styrene-free, polystyrene foam blanks can be safely used to produce boards of the lightest possible weight.

INSTRUCTIONS FOR USE WORKSHOP CONDITIONS SP 115 is optimised for use between 18 - 25°C / 64°F - 77°F At lower temperatures the product thickens and may become unworkable. At higher temperatures working times will be significantly reduced. Low Relative Humidity (<70%) and dry reinforcements are essential, both for creating high clarity laminates to clearly display graphics, and for the development of a full cure. SURFACE PREPARATION Before using the product ensure that the surfaces to be laminated or coated are clean, dry and dust-free. Use only SP Fast Epoxy Solvent (SP Solvent A) for...

The following points must be considered: 1. Skin contact must be avoided by wearing protective gloves. Gurit recommends the use of disposable nitrile gloves for most applications. The use of barrier creams is not recommended, but to preserve skin condition a moisturising cream should be used after washing. 2. Overalls or other protective clothing should be worn when mixing, laminating or sanding. Contaminated work clothes should be thoroughly cleaned before re-use. 3. Eye protection should be worn if there is a risk of resin, hardener, solvent or dust entering the eyes. If this occurs...

TRANSPORT & STORAGE The resin and hardener should be kept in securely closed containers during transport and storage. Any accidental spillage should be soaked up with sand, sawdust, cotton waste or any other absorbent material. The area should then be washed clean (see appropriate Safety Data Sheet). Storage should be in a warm dry place out of direct sunlight and protected from frost. The temperature should be between 10°C (50°F) and 25°C (77°F). Containers should be firmly closed. Hardeners, in particular, will suffer serious degradation if left exposed to air. NOTICE All advice,...
