Application
This unit of competency defines the skills and knowledge required to select and use appropriate resins and resin systems. It includes the chemistry of resins.
Where the selection of a suitable reinforcing system is required unit MEM26007 Select and use reinforcing appropriate for product should also be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Band: A
Unit Weight: 4

Foundation Skills
This section describes those required skills (reading, writing, oral communication and numeracy) that are essential to workplace performance in this unit of competency.
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
Range Statement
This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. | |
Requirements of resin system include the following: | strength flexibility/rigidity surface finish and colour shrinkage chemical/ultraviolet (UV)/environmental resistance operating temperature and heat distortion temperature recyclability |
Most appropriate resin includes the following: | compliance with product requirements greatest ease of use in manufacture best financial return greatest sustainability contribution |
Resin system adjustments include one (1) or more of the following: | temperature humidity required cure time Adjustments may only be made within the allowable limits of the system being used |
Areas for improvement include one (1) or more of the following: | cost/benefit of different resin systems selecting a resin system suited to the fabrication process |
Sustainability includes the following: | survival of the ecology/physical environment economic viability social sustainability |
