CRYSTIC ® E COGEL S3PA - 1

CRYSTIC ECOGEL S3PA Superior Low VOC Isophthalic NPG Marine Gelcoat Introduction CRYSTIC Ecogel S3PA is an isophthalic neopentyl glycol gelcoat, thixotropic and pre-accelerated. This gelcoat is to be applied by spray through an airless machine. CRYSTIC Ecogel S3PA is a low VOC product. Application CRYSTIC Ecogel S3PA has been specially designed for the production of high quality marine parts. It will provide an excellent hydrolysis resistance combined with a high gloss and colour retention. Features and Benefits Features Iso NPG base resin High elongation Special monomers Easy to apply Low styrene content Benefits Excellent water / blistering resistance Good impact resistance Only 28 % VOC Excellent surface aspect Better comfort for the workers and for the neighbourhood Approval CRYSTIC GELCOAT Ecogel S3PA is approved by the Lloyd’s register of Shipping. Formulation CRYSTIC GELCOAT Ecogel S3PA must be allowed to attain workshop temperature before use (18-20°C). It is highly recommended to stir the product with a low shear mixer and then to let it rest before use. The product only requires the addition of catalyst to start curing. We recommend the use of a 50% MEKP ( type Butanox M50) which should be added at 1.5 to 2% in the gelcoat. Gel Time Catalyst level and temperature will influence the gel time. At 25°C, typical gel time of CRYSTIC Ecogel S3PA for 20 parts of gelcoat with 2 % catalyst M is of 8 to 14 minutes. At ambient temperature (20-25°C) the back-up time for a 500 – 600 microns film is about an hour. It is then possible to lay down the first glass reinforcement even if the gelcoat seems still tacky. This tackiness is part of the chemical formulation of the gelcoat. Spray Set Up Application temperature: Dilution: Catalyst : Nozzle airless gun: Pressure : Distance to mould: Thickness

Do Gently stir the gelcoat before use Ensure a workshop temperature between 18°C – 25 °C Spray at the minimum acceptable pressure Apply the gelcoat in thin and even passes until a film thickness of 0.6 – 0.8 mm wet Ensure adequate mould ventilation Apply the first lamination layer within 8 hours Don’t Exceed a wet film thickness of 0.8 mm as as drainage may occur Allow vapor to be retained in deep mould sections, this can slow the cure Apply excessive gelcoat in corners Wait for more than 8 hours before applying the first GRP layer .
