SP 320 - Solvent-Free Clear Epoxy Coating System (v10)

SP 320 SOLVENT-FREE CLEAR EPOXY COATING SYSTEM ¬ Easy application ¬ Excellent Clarity ¬ High film-build INTRODUCTION SP 320 is a solvent-free, clear epoxy coating that provides a high clarity, tough finish to whatever it is applied to. When used for coating wood, just a few coats will provide both protection and a depth of clarity that can only otherwise be achieved with many more coats of a conventional varnish. The epoxy coating will protect most surfaces from moisture ingress, and will also add strength to softwood surfaces. On horizontal surfaces, SP 320 may be poured on as a flow-coat, providing an instant, thick coating layer in just one application. If the coating is to remain unpainted, the cured material should be overcoated with a UV-resistant varnish, since an unprotected epoxy coating will gradually yellow in sunlight. Due to its low viscosity, and excellent wetting characteristics, SP 320 may also be used with lightweight glass reinforcements, such as RE210D, to provide a clear, sheathing layer. When this is further coated with extra layers of SP 320, the result is a glass-reinforced clear coating which is exceptionally strong and hard-wearing. Whilst primarily designed as a coating, SP 320 is completely solvent-free and so can be mixed with the Gurit Filler range to produce filling compounds, adhesives and fillet mixes. Some information about the filler range, and how to use the fillers, is contained in this data sheet. Further details can be found in the Filler Guide.

Instructions for Use Workshop Conditions SP 320 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. When mixing and using product in cold conditions localised heating is strongly recommended for all applications. At higher ambient temperatures the product is "thinner" and more runny, and working times are reduced. Surface Preparation Before using the product ensure that surfaces to be bonded, coated or filled are clean, dry and dust-free. All surfaces...

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 notrecommended, 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 flush...

TRANSPORT & STORAGE The resin and hardeners should be kept in securely closed containers during transport and storage. Storage should be in a warm dry place out of direct sunlight and protected from frost. The temperature should be between 10°C and 25°C. Containers should be firmly closed. Hardeners, in particular, will suffer serious degradation if left exposed to air.
