Frequently Asked Questions
The recommended mixing ratio is either 100:40 or 100:33 (Material-A to Material-B), depending on your specific hardness and curing requirements.
In winter, we recommend preheating both Material-A and Material-B in a small container and using an electrocaloric plate set to 40-50 degrees Celsius to maintain optimal viscosity.
This adhesive is designed for versatility and works exceptionally well with cellulose filter paper, fiberglass media, nonwoven materials, and synthetic polypropylene laminate media.
For a professional finish, use a motor running at 2800 rev/min. The mixing time should be approximately 7-10 seconds per 100g of adhesive.
It is essential to wipe the mould thoroughly with a professional release agent before pouring the mixed polyurethane liquid.
Depending on the temperature and volume, the mixed liquid typically requires 8 to 15 minutes of curing time before the mould can be removed.
