摘要:
The invention relates to coating systems for producing fast-drying coatings which are based on aromatic allophanate group-containing prepolymers and aliphatic polyisocyanates and aminofunctional compounds as the curing agents.
摘要:
The invention relates to new blocked polyurethane prepolymers, a process for their production and reactive systems produced therefrom that harden at room temperature, and their use.
摘要:
The present invention relates to a solvent-free, two component polyurethane coating composition that is suitable for the production of coatings that have long term resistance to temperatures of up to 30° C., have good elongation and withstand cathodic protection, which contains A) a solvent-free polymer mixture containing a component free from OH groups containing at least one of a chlorinated paraffin or dibutoxybenzene, a di-(phenoxy-alkyl) formal, or a polyacrylonitrile, and a component having hydroxyl groups including a component which contains hydroxy groups and ether groups, and optionally a hydroxy-functional polyether polyacrylate and/or another hydroxy-functional compound; and B) a polyisocyanate component containing at least one organic polyisocyanate, where the NCO:OH equivalent ratio is 0.8:1 to 1.5:1.
摘要:
Curable epoxy resin composition comprising a bisphenol based epoxy resin having between 1.1 and 2.5 epoxy groups on average per molecule, a polyhydric phenol curing agent having more than two phenolic hydroxyl groups on average per molecule and red phosphorus. Also are described a process for the production of such curable epoxy resin compositions, the use of the compositions, especially in the impregnation of fibrous fibers, and products comprising or coated by the partly cured or cured epoxy resin compositions, especially impregnated fibrous fibers and laminates made therefrom.
摘要:
The present invention relates to the preparation of new isocyanate-functional prepolymers from styrene-allyl alcohol copolymers and MDI, and also to their use as moisture-curing polyurethane coatings for corrosion control.
