Witton has considerable experience of manufacturing moisture curing polyurethane prepolymers based on MDI, IPDI, oligomeric isocyanates and silanes in combination with polyols for use in sealants and adhesives. We can handle and use moisture sensitive materials, flammable solvents, viscous liquids and undertake formulation & blending.

Note we do not use TDI or HDI due to their very high volatility and toxic properties.
