What is Glitterflake?

Fibre Glast Glitterflakesare .015" metallized polyesters flakes typically used with a clear gel coat. We recommend our#180 Clear Gel Coatwhich is an ISO/NPG marine gel coat with excellent weathering properties and a high gloss suitable for glitterflake.

Using Glitterflake In a Mold

Typically,glitterflakeis used in molding applications. It is necessary to first apply 12 – 14 mils of wet catalyzed gel coat. It is important to catalyze this cover layer at the recommended levels as over or undercatalyzation can cause various problems including premature yellowing, cracking and a reduced gloss. We recommend that this cover coat be allowed to tack up before proceeding.

Theglitterflakecoat should be applied directly behind the cover coat. Normally, glitterflake is added at 10% by weight, but this may be increased to up to 20%. In excess of 20% can cause curing problems including a distortion or ripple in the surface. Also, mixing the glitterflake with the gel coat should not be done more than one hour before it is to be applied.

Catalyze the glitterflakegel coatat the recommended level and apply a wet layer of up to10-20 mils.

Theglitterflakelayer will not provide a total hide and some visible changes in the orientation of the flakes will be present. We recommend using a pigmented layer directly behind the glitterflake layer which will hide the reinforcement and offer an improved final appearance. Typically, a contrastingpigment coloris used such as black with silver or gold or white with red or blue.

Often, this pigmented layer is a reinforced gel coat layer, as there are already about 25 mils of gel coat on the mold and a reinforced layer will help avoid problems as well as offer added strength.

Equipment

Conventional gelcoat spray equipmentis typically used. Theglitterflaketends to clog so experimentation with larger nozzles may be necessary. Also, problems can occur if there are "hot spots" or over catalyzed areas in thegel coat. This can be a particular problem in equipment which does not provide even catalyst disbursement. Hot spots tend to blister and will show significant color change.

Repairing Glitterflake

Glitterflakeis difficult to repair. It comes in a wide variety of sizes and colors and many types will turn bright silver if they are directly sanded. Consequently, minor surface repairs should be done only on the clear, careful to avoid the flake. In the event that no first clear exists, a clear patch must be applied.

Applying Glitterflake To An Outside Surface

Rough the entire surface to be repaired. Complete any glass repairs and allow to fully cure before proceeding with the glitterflake repair. Feather sand the repair area and wash with#9 Acetoneor other solvent and allow to completely dry before proceeding. Mask off a large area around the repair. Apply a backup layer of catalyzed pigmented gel coat or resin and allow to dry. Next, mix the desired amount of Glitterflake and clear gel coat and catalyze. Apply a layer 12-20 mils thick and cover with peel ply, wax paper or cellophane. Smooth the area and allow to dry before removing the cover. Overspray with clear gel coat 12-14 mils thick. The addition of#71 Styrene Waxwill insure a tack free finish. Allow to completely cure and then buff. If additional gloss is needed, wet sand with600 grit sandpaperand polish to luster with boat polish.

Scratches can be repaired by wet sanding with a600 grit sandpaperand then polishing back to luster with a boat polish.

If no clear layer is present, it is necessary to apply a clear spray, so you have an area to feather into. We recommend adding#71 Styrene Wax通用电气的l coat before catalyzing. Spray the catalyzed gel coat and allow to cure completely, usually 24 hours. Use600 grit sandpaperand scuff an area larger than the repair. Be careful not to sand too hard and damage the glitterflake. Wash with#9 Acetoneor other solvent. Continue as outlined above, applying apigmented layer, aglitterflakelayer which must be smoothed and a final clear overspray. It is possible to use a brush on small repairs, but we recommendspraying gel coatwhenever possible.

Glitterflake Safety

Althoughglitterflakeposes no unique hazards in itself, it is wise to work in a well ventilated area whenever working with gel coats or use adequate respiratory protection.Glitterflakeis easily suspended in air however, and you may find that it travels easily and will find its way to unwanted areas if you are not careful. We have found that papermixing and measuring toolswork better than plastic or metal for this reason.
