The development and optimisation of polymerisation processes is a core part of Witton's business. Most monomers can be handled and reacted with redox initiators or thermal initiators such as peroxide and azo initiators. Polymerisation reactions can be carried out in water or solvent. Molecular weight can be controlled by choice of reaction conditions or by use of an appropriate chain transfer agent.
Our reactors are equipped with condensers and solvent can be stripped from polymer solutions using vacuum if required. The company is skilled in the production of latexes for use in coatings and surface treatments.
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.
