Product Description

Vinyl ester tooling Gel coat

Product Description

Description

Vinyl ester resin base tooling gel coat is formulated
specifically for composites mold application.
It can be exhibits high heat distortion to withstand the repeated molding of FRP laminates. These products do not contain lead. They are formulated to provide abrasion resistance, good gloss retention, High HDT and extended mold life.  

Package
20kg with PE liner.

Shelf life
- 3months under 25ºC,away from  heat sources, direct sunlight or steam pipes,rain etc.
- Keep sealed to prevent moisture pick-up and monomer loss.

Application attention:
- Generally best results are obtained by applying two coats at 18mils wet each, and allowing the gel coat to gel and cure between coats. Apply each coat with a minimum of two passes; three passes are preferred. For best results, ensure that the tooling gel coat is allowed to "breathe" for two minutes between each pass. Do not allow over-spray and thin passes to go beyond 5 minutes without covering with a fresh pass.

- Recommended Gel time be checked in the customer's plant because age, temperature, humidity and catalyst will produce varied gel times.

- Do not use more than 3.0% catalyst in the tooling gel coat, as this can cause excessive shrinkage of the gel coat and pull it away from the plug. For adequate cure, do not use less than 1.2% catalyst.

- Normally, tooling gel coats are ready to lay-up on (or spray with a second coat of gel coat) in 60 - 90 minutes.

- Using conventional tooling resin, the gel coat should not be left overnight before being laminated  as the gel coat may pre-release or lose its stick

- UV and moisture resistance will be limited due to vinyl ester resin . Recommended that molds  should be stored outside away from UV and moisture exposure. This may be accomplished by covering the mold or inverting the mold so that the surface is not exposed to UV and that moisture cannot collect on the mold.

- Tooling gel coats may leave a certain amount of "color" when sanded and/or buffed. This is a function of the pigment used and is not an indication of cure.

- Do not add anything, other than the appropriate methyl ethyl ketone peroxide, to these products.

Total tooling resins solutions for composites mold

We could offers a full line of tooling resins for all methods of tooling manufacture. These products include epoxy ,unsaturated polyester, vinyl ester and a series of low profile resins.

- Tooling gel coats are formulated specifically for mold making. These series contain both special polyester and vinyl ester products.

- Skin coat.Superior mold cosmetics can be achieved by using a skin coat with hybrid vinyl ester resin behind the gel coat. Be applied after the gel coat application and offer good protection from fiber-print and distortion on the gel coat surface in order to increase mould turnaround time.

- A full line of tooling resins for all methods of tool manufacture. These products include a vinyl ester and a series of low profile resins. The vinyl ester resin can be used as skin and bulk materials in the conventional mold building process. This process consists of daily single ply lamination until the required mold skin thickness is achieved.
