1 Ampreg 22 Epoxy Laminating System Optimised for open-mould laminating of large structures Improved health and safety Lloyds and Germanischer Lloyds approved Ampreg 22 is one of a new generation of epoxy laminating systems from SP Systems which has been developed from the extremely successful and widely used Ampreg 2. It is intended for both wet lay-up and vacuum bagging processes and uses the most up-to-date epoxy chemistry available and is ideal for the manufacture of large, high performance composite structures. The Ampreg 22 system currently consists of a resin and two hardeners with other hardeners available shortly. With its Extra-Slow hardener Ampreg 22 can provide laminate working times of over 9 hours at 2 C whilst having low exothermic reactions even when used in thick sections. By pre-blending the with the hardener a broad range of other working properties can be obtained. If used on its own, the hardener has such rapid through-cure that it can be used to produce small mouldings in just a few hours at 25-3 C. Ampreg 22 resin is coloured yellow, the hardener yellow/brown and the hardener blue. This makes component identification easy, and facilitates thorough mixing of resin and hardener. Ampreg 22 resin has one of the lowest diluent contents of any epoxy resin system available today. Together with the use of some unique chemistry in the hardeners, the overall system shows marked improvements in handling safety over other products. This aspect is particularly important for those using the product in open-mould, hand lay-up applications, where exposure to skin contact and vapours can be difficult to avoid completely.. A

5 SP Systems Important Notice The policy of SP Systems is one of continual development and improvement. Therefore the right is reserved to alter specifications and prices without prior notice. Any information, data, advice or recommendations published by SP Systems or obtained from SP Systems by other means and whether relating to SP Systems materials or other materials, is given in good faith. Whilst such information, data, advice and recommendations are believed to be reliable, it is intended for use by persons at their own risk. SP Systems assumes no responsibility for events resulting or damages incurred from their use. Furthermore, they are not to be taken as a licence to operate under or intended to suggest infringement of any existing patent. It remains at all times the responsibility of the customer to ensure that SP Systems materials are suitable for the particular process used and purpose intended. SP Systems therefore strongly recommend that representative trials are carried out and test pieces and component sections built and tested by the user in order to define the best process and materials to use in the desired application. This should be done under conditions that are as close as possible to those that will be used in the intended application. SP Systems data, information and instruction sheets are also being continuously reviewed and updated with changes and additions. Although the registration scheme for the Handbook and CD-ROM will ensure that registered users of these publications will receive periodic updates, there will always be some changes that are not immediately communicated. It is therefore essential that any user check that they have the current version of any data, information or instruction sheet before specifying, purchasing or using any SP Systems product. This can be done by contacting SP Systems Marketing Services and quoting the revision number that is on every page.

The data is intended to show typical values for a product and is not to be taken as guaranteed minima. Due to natural variations in raw materials, manufacturing processes and testing, there will be some spread in this data from test to test and batch to batch. This spread should be taken into account when specifying or using any SP Systems product. Where some of the test methods are also used for SP Systems internal Quality Control purposes, more information on this spread may be available from SP Systems Quality Control Department, which can be reached at the main SP Systems contact numbers and address.
