Introduction
SC 110 is a new cosmetic grade prepare that utilises a high clarity, versatile, hot-melt epoxy resin formulation.
The unique formulation ensures that no dicey white-wash or spots are evident in the cured resin, reducing scrap rate by up to 20%. It is ideal for manufacturing high visual quality components using autoclave and press moulding. It can be cured at temperatures as low as 80°C, or it can be used for faster moulding of components at 120°C. Even faster cures are achievable using press moulding technologies at temperatures up to 150″C. This is achieved whilst maintaining good out-life of up to 3 weeks at 21″C. It is a toughened system, and offers excellent mechanical properties on a wide variety of reinforcing
Features :
Ultra high clarity- ideal for cosmetic components with no white-wash or spots
High-strength prepreg system
Versatile process window with autoclave, and press moulding
Curable at temperatures as low as 80°C
Fast 1 hour cure at 120°C
Rapid 10min cure at 150°C in a press
Excellent tack allowing easy in-mould repositioning
ROBUST DEVELOPMENT VALIDATION
During the development of SC 110, extensive beta testing has been conducted to manufacture the most challenging cosmetic components in order to demonstrate the robustness of the unique dicey-free resin formulation. Light curvature, resin rich seams and numerous components have been produced through autoclave and press moulding processes without any sign of white wash or spots.
IMPROVED WEATHERING PERFORMANCE
In order to measure the weathering performance, SC 110 was benchmarked using a OUV SE Accelerated Weathering Tester with the following cycle: 4hrs condensation at 50°C I 4hrs UV exposure at 60°C I 28 days of exposure.
The subsequent loss in gloss measurement after 28 days was found to be significantly lower than competitor materials.
