According to Sicomin, two of its advanced resin systems successfully achieved certification; these include SR 1280, a low viscosity hand-laminating epoxy system, and secondly SR 8100, a very low viscosity infusion epoxy system.
Sicomin participated in the LR’s application process which involved thorough assessments and rigorous test procedures. Both the SR 1280 and SR8100 systems were subsequently approved for use in the construction of marine craft built under the Lloyd’s Register’s Survey.
Sicomin state it developed SR 1280 in response to manufacturers looking for a low viscosity, easy hand-laminating epoxy system. Used in conjunction with the hardeners SD 4770 (very slow) and SD 4775 (fast), the system can be mixed for intermediate reactivity. During Differential Scanning Calorimetry (DSC) tests, SR 1280’s Tg onset is calculated at approximately 100°C therefore demonstrating good mechanical properties.
Furthermore, the company explains the SR 8100 is designed specifically for infusion and RTM techniques. In addition to LR certification, SR8100 has also achieved Germanischer Lloyd approval and is utilised by many of Sicomin’s Industrial, Marine, Energy, Transportation, Sports and Leisure customers.SR 8100 is a two component system and is compatible with a variety of hardeners allowing the construction of small to large parts with rapid remoulding time.
