Frequently Asked Questions
Maintaining the 100:40 ratio of Material-A to Material-B, combined with 40% talcum powder, ensures the optimal cross-linking density, providing the necessary rigidity and leak-proof seal for industrial filtration.
Preheating reduces the viscosity of the polyols, allowing for more efficient mixing and better penetration into the filter media fibers, which results in a stronger mechanical bond.
Yes, our two-component polyether polyol system is highly compatible with fiberglass, cellulose, and synthetic media, making it a versatile choice for various air filter types.
Humidity can influence the curing rate of PU adhesives. We recommend monitoring your workshop environment and adjusting the mixing time or curing duration slightly to maintain consistency.
These fillers act as reinforcing agents that increase the hardness of the cured adhesive, reduce shrinkage, and lower the overall material cost without compromising the seal quality.
Using a motor at 2800 RPM for the specified mixing time and applying light pressure when placing the paper element into the mould helps eliminate voids and ensure a dense, bubble-free finish.
