Introduced to injection molders in 1985, Per-Fix was born out of a direct need of our molding customers. "Can you make anything that will help us get rid of knit and flow lines?" No coating like this had ever been developed, (before or since) but we took on the challenge and created Per-Fix. Now, you can spray Per-Fix onto your flawed parts and watch your problems disappear. See for yourself how amazing Per-Fix is.
If you are molding matte finished, color-coded, textured, interior parts, and cosmetic flaws are a problem, this is a tool you need. You will be amazed at how much easier this will make your job, and how much time and money it can save you.
What kind of plastic are you molding?
We have a coating for almost everything!
Our five systems include:
8205 ABS
Provides a permanent, micro-thin, transparent coating to eliminate cosmetic flaws. Gentle system that will not harm ABS. Quick drying. Use on ABS, Cycolac®, glass filled Nylon®, and other similar resins.
7205 Polypropylene
The Original Flaw Repair Coating. Great for Polypropylene and also our best "all-around" coating. Dries quickly and provides excellent adhesion. Works well with many blends. Use on Polypropylene, Cycoloy®, Xenoy® and other PC/ABS blends, TPO, and other similar resins.
6500 Styrene/Polycarbonate
Specially developed for use on these solvent sensitive plastics. While mild enough to spray on a Styrofoam cup with no ill effects, its adhesion and effectiveness are outstanding. Use on Styrene, Polycarbonate, Acrylic, HIPS, Polystyrene, and other similar resins.
6405 Vinyl/PVC
Formulated with adhesion and flexibility in mind. Use on Vinyl, PVC, Estane®, Noryl®, PPO, PPS, Pellethane®, Rubber, Sheet Molding Compound, TPE, TPU, Ultem®, and other similar resins.
5205 Nylon®
Specifically developed to provide excellent adhesion to Nylon® and Nylon® blends while masking surface flaws. It brings the part to a perfect surface condition which is both transparent and permanent. Use on Nylon®, Nylon 6/6®, Celeon® and other Acetals, PBT, PET, Polyimide, TPO, and other similar resins.
Cross Use of Products: Cross use of products on resins not specified is acceptable as long as adhesion is tested and found to meet your criteria. Adequate pre-use testing should include coating several parts, allowing the coating to cure for 24 hours and then performing an adhesion test as specified in ASTM D3359. (Test methods available upon request from chem-pak.)
Per-Fix is designed for use on all interior, textured, matte finished, plastic parts. We do not recommend Per-Fix for parts that will be used outdoors or in exterior applications. No warranty, either expressed or implied is granted on any application of the product in an exterior setting. Warranty is limited to replacing or accepting return of any defective coating material. We recommend thorough performance testing of Per-Fix prior to any large-scale commitment of use.
