It has novolac based formula which guarantees the highest mechanical and chemical resistances, notably to styrene. Polyester or vinylester parts manufactured on the 2060 GC ALU gelcoat will release with high gloss for numerous cycles. Should the gelcoat needed to be repaired, polishing the repaired area will enable to regain a high gloss surface aspect. This new generation system, optimized with excellent self leveling characteristics and excellent air release, is suitable for the manufacture of large composite tooling. It can be applied by brush while guaranteeing low toxicity working conditions to the users. The high thermal conductivity & stability under temperature of the 2060 GC ALU enables it to be the product of choice for 250°C Acrylic sheet thermoforming. The recommended application thickness ranges from 500 um to 600 um at 23°C, which it is possible to achieve in one coat on a vertical surface without sag. Final thermomechanical properties will be obtained after a post curing cycle defined later in this technical datasheet.

- Applications
- It is recommended to have workshop temperature conditions between 18-25°C in order to facilitate the mixing and the application. A lower temperature ill increase the viscosity of the mix as well as its pot life. On the contrary, a higher temperature will reduce the viscosity and the pot life of the mix Thoroughly mix the resin part before pouring in mixing cup. It is recommended to mechanically mix the resin +hardener during 5 effective minutes to ensure effective mixing and do a double potting before use to ensure all the resin and hardener have been correctly mixed and that un-mixed resin or hardener left on the sides of the first mixing pot are not used.
- The standard procedure of working with epoxy gelcoats applies this system. The 2060 GC ALU / 2062 or 2066H system can be applied by brush. This gelcoat has been formulated for application of 500 to 600 um without sag on vertical surfaces in one only coat. Coverage: 0.8 - 1.0 kg/m for a 500 -600 um thickness dry film. Over coating As an indication, it is possible to overcoat the gelcoat with a laminating resin as long as the surface still has tack (timing to be defined by workshop temperature & hardener choice). It is recommended to sand and degrease before laminating onto the gelcoat if the surface has cured and formed its fim (tack-free surface).
- Other application methods such as delaying the gel by applying a coat of ultra slow laminating epoxy resin (1050 1053S RESOLTECH system is recommended for this use) onto the freshly applied gelcoat is a well proven method and ensures a good chemical bonding with the reinforcement laminated within 24h of the 1050 / 1053S coat Lamination of the first layers of reinforcement may be done with the aluminum filled 2060 ALU 25 resin in order to improve mold print-through resistance and better thermal resistance of the mold surface. In all cases testing in production conditions should be conducted in order to validate the method before industrial size applications.

Safety & Health
- Health & Safety
Skin contact must be avoided by wearing protective ni- trile gloves & overalls or other protective clothing. Eye protection should be worn to avoid risk of resin, hardener, solvent or dust entering the eyes. If this occurs flush the eye with water for 15 minutes, holding the eyelid open, and seek medical attention. Ensure adequate ventilation in work areas. Respiratory protection should be worn with ABEKP coded filters. Resoltech issues full Material Safety Data Sheet for al hazardous products. Please ensure that you have the correct MsDS to hand for the materials you are using before commencing work.
