We have the following five colour charts available for online viewing. All colours are available in organic based versions, where appropriate, to give a heavy metal free product with maximum lightfastness readings.
Please note the colours shown should be used as a guide only due to varying degrees in monitor colour management.
The Llewellyn Ryland Standard Range has evolved over the past fifty years as a most popular selection of colours used in a wide variety of applications for composite mouldings. As well as their popularity as polyester dispersions this colour range is also available in epoxy, polyol, aqueous and other specialised dispersions as well as polyester gelcoats - all with very quick delivery.
The British Standard BS5252 establishes a framework within which 237 colours have been selected as the source for all building colour standards and the means of co-ordinating them. A colour is only standardised when it is included in another British Standard, such as those derived for paints (BS 4800), vitreous enamels (BS4900), plastics (BS4901) and sheet and tile flooring (BS4902). Each separate standard contains only a proportion of BS5252. The BS5252 framework itself locates and relates the colours in terms of selected steps in the visual attributes of hue, greyness and weight.
RAL was established in Germany in 1925 as a committee for rationalizing terms and conditions for orders and deliveries. RAL was a common foundation of industry, trade and public authorities. The first range of German industrial colours was given into the custody of RAL in 1927. Whilst the RAL colour range may have originated in Germany, the colours are used as standards in all West European countries and consequently in all countries throughout the world trading with Europe. The 183 colours illustrated are relevant to composites manufacture with applications in land transport, machinery, architecture, design, etc.
The 18 Llewellyn Ryland standard range of polychromatic / metallic colours represent the most popular shades used. Other colours in polychromatic, metallic and pearlescent shades can be produced to special order. To achieve a uniform finish with polychromatic and metallic colours, spray application of the gelcoat is recommended. A greater depth and richness to the gelcoat surface will be obtained by suitably colouring the lay up resin. Polychromatic and metallic colours are only produced as polyester colour pastes because of possible settlement in pre-coloured gelcoats in storage. The colours illustrated represent a 10% addition by weight to clear / natural gelcoat.
The Llewellyn Ryland standard transparent range consists of eight colours. These eight colours are intermixable amongst themselves to give a much wider range and when required we can colourmatch to customers' specification. For transparent colours the amount of colour paste required varies from 3% to 10% depending on the thickness of the GRP sheet or casting, the resin and, where appropriate, the reinforcement used and the depth of the colour required.
