    Abstract: The present disclosure provides an antifouling coating and a use method and use thereof. In the antifouling coating of the present disclosure, polyaspartic acid ester is an isocyanate curing agent containing a secondary amine structure. An ester group and aliphatic properties in the polyaspartic acid ester can increase wear resistance of the coating. The polyaspartic acid ester is combined with a polyisocyanate-containing prepolymer in a component A to endow the antifouling coating with desirable toughness and elasticity, such that the antifouling coating has excellent impact and abrasion resistance. In the component A, a polydimethylsiloxane structure is introduced into the hydroxypropyl silicone oil-based isocyanate prepolymer. The polydimethylsiloxane structure can generate microphase separation with a polyurea hard segment and migrate to a surface of the coating, thereby reducing surface energy of the coating to reduce an adhesion between fouling organisms and an interface.

    Abstract: A quick-drying solvent-free sag-resistant polyurethane waterproof coating and preparation method therefor, raw materials therefor comprising a polyurethane prepolymer, a plasticizer, a dispersant, a filler, a dehydrant, a catalyst, a defoamant, and an oxazolidine reactive diluent. The catalyst is composed of pentamethyl dipropylene triamine, tetramethylethylenediamine, and 1,8-diazabicyclo[5.4.0]undecene. Raw materials of the polyurethane prepolymer comprise a polyether diol, a polyether triol, an isocyanate, and a chain extender. The prepolymer is prepared by means of the following method: 1) measuring out the raw materials for the polyurethane prepolymer, and reacting the polyether diol with the isocyanate until reaction is complete; 2) then adding the polyether triol for reaction until reaction is complete; 3) then adding the chain extender for reaction, completing preparation. The waterproof coating preparation method is: i) preparing the polyurethane prepolymer; ii) mixing the prepared polyurethane prepolymer with the rest of the raw materials for the waterproof coating to obtain the final product. The present waterproof coating features such advantages as exceptional film-forming speed and sag resistance, and low viscosity.

    Abstract: The present invention relates to reactive compounds for the production of polyurethane layers, said compounds comprising an isocyanate component composed of at least one polyfunctional isocyanate, an oligomer of a polyfunctional isocyanate or an isocyanate prepolymer, a polyol component composed of at least one polyol, and a catalyst system comprising a metal-based catalyst based on a salt or an organometallic compound and a diketo compound having a melting point of ≥15° C. The catalyst system has the characteristic feature of low toxicity and very low reactivity under processing conditions, but can be activated by increasing the temperature, with the result that polyurethanes that have reacted as far as possible can be formed in a short time. The present invention further relates to methods for producing such polyurethane layers, to polyurethane layers produced from the reactive compounds, and to composite structures that comprise such polyurethane layers. In addition, the present invention relates to the use of the specified catalyst systems for the reaction of polyols and polyisocyanates.
