SPL's initial product was RCM, a thermoplastic resin coating that could be applied to the primary resins used by telephone manufacturers. However, as SPL's customer base changed and new products came on the market, customers' suppliers modified the resin base they used and we found we needed a coating that could be applied to a greater variety of resins. Initially, we used a primer coat prior to applying our RCM, but this step meant the coated product was no longer recyclable. After much development work, we created a recyclable, thermoplastic, waterborne coating, RCM-WB(SA) that allows almost all thermoplastic resins to be coated.
Although developed to assist us with re-coating work, the product is now being used to coat virgin parts that require a colour coat (Why Use RCM-WB(SA)).

WHY USE IT ?

SPL developed this thermoplastic resin based coating for use on newly moulded plastics for electronics, office equipment, telecommunications, computer, printers, etc. RCM-WB(SA) can be used to hide blemishes, flow lines, mould marks, pigment blooms, as well as for spot colour corrections or complete colour coatings.
SPL's RCM-WB(SA) offer a number of advantages over traditional paints.

• RCM-WB(SA) literally welds to the plastic surfaces, eliminating the possibility of chipping and peeling, common problems with paints.
• SPL manufactures its coatings to very stringent colour standards. SPL's coatings are manufactured to an FMC DE of less than 1.5 ensuring each coating is directly matched to the application requirements. Thus, RCM-WB(SA) can be applied as a touch-up with no perceivable colour mismatch with the substrate.
• SPL formulates its coatings to be compatible with the plastics to which the coatings are being applied. The coatings do not constitute a contaminant when recycling is a consideration.
• The dry coating is thermoplastic and therefore melt compatible with the substrate plastic and coated products can be directly recycled back through the manufacturing process.
• SPL coatings are applied using very little material, thereby achieving a cost savings.
• Although more expensive than SPL"s RCM, RCM-WB(SA) is a waterborne material and environmentally friendly. Its volatile organic compounds (VOCs) are less than 200 grams per litre (1.7 lbs per US gallon).
• RCM-WB(SA) is a single component coating. Unlike traditional paints it has an indefinite pot and shelf life.
