What is the difference between a single component and a two-component polyurethane coating?
Polyurethane waterproof coating two-component, one-component two.
One-component polyurethane waterproof coating construction is convenient, to overcome the two-component polyurethane waterproof coating to measure the shortcomings of mixing, to ensure product quality and engineering waterproofing effect.
One-component polyurethane waterproof coating, without coal tar, petroleum resin, asphalt and organic solvents, no pollution to the human body and the environment, can be made into a variety of colors, beautify the environment. Cationor: Isocyanate, in the moisture or organic amine catalyst Self-crosslinking curing, the application period, 6-24 hours. Storage stability, in years as a unit, less paint.
Two-component sub-group, two groups. A component is a giant carbamate prepolymer containing a diisocyanate group (-NOC) prepared by polymerization reaction with a raw material such as a polyether resin and a diisocyanate; the component B is a binder, Tougheners, tackifiers, fungicides, fillers and diluents, and other mixed processing. One component is the use of mixed polyether dehydration, adding diisocyanate and a variety of additives made of epoxy modified. Two-component and one-component are asphalt-based environmentally friendly materials. Group A Group B in accordance with the proportion of mixing, stirring evenly, you can use, the application period 4-10 hours,
