This nylon reinforced resin film is made to be placed on the surface of the molds to give a resin rich surface for parts that are intended to be post finished or painted. Having a resin rich surface will give you a better looking part cosmetically as well as give you an opportunity to further sand/finish your part without sanding into the fibers and ruining the structural integrity of the parts. This epoxy is the same epoxy that is used in our other 250° F cure prepregs so you have a complete system that is compatible together. To use this material just cut to shape, pull off the plastic liner, place in mold, place layers of prepreg reinfocment down, vacuum bag the material down and ramp up the heat to 250° F for one hour and your part is done. If you are making parts where you want to see the weave of the carbon fiber then you need to use our clear surfacing film. This nylon reinforced file is intended to be used for parts that will be painted such as a sattelite dish.
This product is 50" wide and sold in 10 yard, 25 yard and 50 yard segments. We do not sell this by the cut yard because it is stored in a freezer and must stay frozen to comply with shelf life requirements. Please use the dropdown below to select the roll length.
- 0° F (standard freezer) - 1 Year
- 40° F (standard fridge) - six months
- 72° F (room temp) - 30 days.
It is suggested to store at 0° F or below to provide a longer shelf life. If you plan to use material faster, then you can store at a warmer temp to shorten the time it takes to get material to room temperature.
Cure time: This product needs to be cured at 250° F for One hour. You can cure at 200° F for 2.5 hours, however you will not get the same "tg" glass transition temp (temp range where the resin changes from a hard rigid state to a more pliable "rubbery" state) of the finished part.
Application: Remove material from cold storage at least 20 hours prior to use so the material stabilizes at room temp. Keep the material wrapped to prevent moisture from condensing on the adhesive. Cut prepreg to the correct size, remove poly film from one side and apply to part or mold. Then remove the backing paper. Now apply your desired layers of reinforcement materials. When your lay-up is finished, you need to cure the material in a vacuum bag placed inside an oven or autoclave. Apply at least 10psi of pressure and 250° F for one hour.
Caution: This material contains epoxy resins and amines which may cause irritation to sensitive skin. Avoid contact with eyes or skin. If contact with skin occurs, wash as soon as possible with soap and water. If contact with eyes occurs, flush with water for 15 minutes. Do not handle or use this material until Material Safety Data Sheet has been read and understood. The user of this material is required to use the necessary protective equipment as directed by applicable state and federal laws when handling, curing, and grinding this material.
Shipping: This material should be shipped expedited airmail. Due to a short shelf life at room temp we suggest shipping this material via an expedited service such as UPS Overnight, 2-day or 3-day. These are guaranteed services. If these are chosen, we will ship the materials in the beginning of the week to ensure they do not sit in the shipping company warehouse over the weekend. We can send the material with insulation and icepacks at an additional cost (add $25 for ice packs and insulation). It is suggested that you ship with ice packs and 2-day airmail at a minimum. If you plan to use material within days of arrival or are OK with loosing days of shelf life, you can select any shipping method you would like, however if our minimum suggested shipping method is not chosen, we will not be held responsible for issues with material.
Custom Prepreg Options
We can have almost any of our fabrics pre-impregnated for you. Please email us for more details. We have systems that can cure at various temps from 200° F to 350° F. We can do a max width of 60". Lead times are usually 2-3 weeks for custom prepreg. We can do single side or double sided prepreg, vary the resin % in the cloth and vary the tack level of the material.
