GSA Backup Coat
GSA Backup Slurry is made with Polybond Backup and HPF II F a high-performance flour blend and the Stucco is fused silica 30/50 and 10/20.
HPF II F
HPF II F is a blended flour made from fused silica, combined with high-performance additives and organic fiber. It is specifically designed to create a uniform coating thickness at the edges and prevent shell cracking during autoclaving
The backup coat having the below benefits:
- Excellent slurry for backup coats with improved edge buildup.
- Provides thicker shell build with reduced number of dips.
- Fast drying to increase the foundry output.
- Excellent autoclave performance with no shell cracking.
GSA 6570
GSA 6570 is an anionic organic surfactant designed for use in investment casting slurries.
Benefits & Features:
- Enhances the wetting of refractory flours during slurry preparation.
- Improves slurry adhesion to wax patterns during dipping.
- Specially formulated for the investment casting industry
- Promotes a smooth surface finish while minimising surface-related casting defects
GSA Antifoam 2
GSA Antifoam 2 is a water-dilutable silicone-glycol emulsion designed to control foam in various aqueous systems.
- Provides rapid antifoaming action preparation.
- Easily disperses in its supplied form or when diluted.
- Readily dilutable in DM water.
- Ensures long-term antifoam effectiveness in water-based investment casting slurries.
- Formulated to prevent casting defects caused by bubble formation during slurry drainage.
