should not be interpreted as technical specifications.The gel times shown are typical values but may be affected by catalyst, accelerator, and polymerization inhibitor concentrations, as well as resin, mold, and shop temperatures. Gelation characteristics may vary with different types of initiators and under conditions of extremely high humidity. Pigments and/or fillers may delay or accelerate gelation.Manufacturers are advised to verify the gelation characteristics of a small amount of resin under actual operating conditions prior to use.

2,4-P: 2,4-pentanedione; DMA: dimethylaniline; DEA: diethylaniline;
Curing system: 100 g resin + 0.1 g 6% cobalt + 0.1 g DMA. The DMA content should not be less than 0.1%, or the DEA content should not be less than 0.2%. 0.2% DMA can be used in place of 0.1% DMA.
Process Operating Guidelines
- Maintain the curing agent dosage between 1.0% and 2.0% of the total resin weight to achieve sufficient cured strength;
- The workshop temperature should be maintained between 18°C and 32°C, and the humidity should be maintained between 40% and 90%. Consistent workshop conditions will ensure a consistent gel time and help manufacturers produce high-quality products.
- Finished products cured at room temperature in contact with air should have a surface that is relatively non-tacky to the touch.However, they may not be fully cured and therefore may not exhibit the same chemical resistance as fully cured products. If no further layering is planned, add 10% of a styrene solution containing 5% paraffin wax (melting point: 46–48°C) to the final layer of resin to achieve a non-tacky surface.
- For room-temperature curing promoted by a cobalt salt solution, use an MEKP initiator with a high dipolymer content to minimize foaming in the Vipel® F013 series.
- Vipel® F013 series composite products that have already been cured at room temperature can be post-cured for two hours at 70–100°C to achieve optimal curing and performance.
