A solvent-based cement suitable for plastic model kits only. The product is a low viscosity version of Humbrol Poly Cement to enable application by brush. Substrate: Common plastics used to manufacture model kits including polystyrene and ABS. The product works by melting the plastic on application and 'welding' two glued pieces of plastic together to form a strong bond. Coverage: Depends on thickness of application. Application Directly onto plastic model kits. An integral brush is supplied. A cocktail stick can be useful to apply sparingly to small areas or fine details. Drying time: Surface dry in 10-20 minutes. Fully dry in 1 hour. Drying times will vary according to ambient temperature and humidity. How to clean: Can be removed if not fully dry by re-dissolving with more Liquid Poly or Poly Cement. Permanent once dry.
