Does the MO machine use solventless adhesive, and is that suitable for insulation materials? Yes, the MO typically runs solventless (100% solid) adhesives, and this is actually ideal for insulation materials. Solventless adhesives do not release volatile organic compounds (VOCs), which is important because thick insulation can trap solvents and cause delamination or odor problems. The adhesive is applied by a metering system that can handle higher coating weights (often 3–15 g/m²) to bond rough or porous insulation surfaces. Some MO machines also have a hot‑melt adhesive option for materials that require instant bonding. https://www.sinstarsl.com/mo-insulant-laminator
