| BASIC EPOXY CHEMISTRY (Part 2) |
Laminating The term laminating refers to the process of bonding numbers of relatively thin sheets, like plywood, veneers, fabrics or core material. The laminate may be any number of layers of the same material or combinations of different materials. Methods of epoxy application and clamping will differ depending on what you are laminating. Because of large surface areas and limitations of wet lay-up time, a roller is the most common application method. A faster method for large surfaces is to simply pour the resin/hardener mixture onto the middle of the panel and spread the mixture evenly over the surface with a plastic squeegee. Apply thickened mixtures with a notched squeegee. Staples or screws are the most common method of clamping when you fasten to a solid substrate. An even distribution of weights will work when you are laminating over a base that will not hold staples or screws, such as a foam or honeycomb core material. The ideal clamping method is vacuum bagging, which, through the use of a vacuum pump and plastic sheeting, applies perfectly even pressure over all areas of the panel regardless of the size, shape or number of layers. For more information about vacuum bagging, refer to 002-150 ADVANCED VACUUM BAGGING TECHNIQUES. =========== Work In Progress ======== back to Page 1 |
