HX-CECO Powder™ Latex Thickener
A specialty filler for natural latex. HX-CECO Powder is a blend of powders and surfactants that thickens the coats applied after the first few coats on a mold, letting you reach a desired thickness in far less time and with fewer coats, while increasing the strength of the rubber.
- Build mold thickness faster with fewer coats
- Fills undercuts and smooths the outside surface of molds
- Increases mold strength and tear resistance
- Mixes easily into natural latex without harming the rubber
- Recommended after the first four coats of latex
Product Overview
HX-CECO Powder is a specialty thickener for natural latex mold-making rubber. Mixed into later coats of latex, it helps build mold thickness more quickly while increasing strength and tear resistance.
It is especially useful for filling undercuts, building flange areas and creating a smooth outer surface that can be properly supported by a mother mold or support shell. HX-CECO mixes easily into latex and is typically used after the first four coats have been applied.
Application Summary
- Apply the first four coats of latex without HX-CECO Powder.
- Mix HX-CECO into latex until a smooth paste consistency is achieved.
- Use the thickened latex to fill undercuts and build flange areas.
- Build thickness gradually to ensure proper drying.
For complete instructions and technical details, refer to the Technical Bulletin.
Mixing & Curing Notes
Building up the base and undercuts gradually creates a smooth, rounded outer surface against which a mother mold (support shell) can be built without gaps, so the shell supports the latex at every point and avoids future problems.
Do not use if you have latex allergies. Store and use at room temperature (73°F/23°C); do not allow to freeze. Always consult the current Technical and Safety Data Sheets before use.
