    Preparation of polyurethane primer: Match polyurethane A and B in a ratio of 1:2 3 (weight ratio) (other coatings are matched according to the proportion specified in product specifications).

    When the B material is thicker, it can be diluted with a special diluent, and must not be diluted with acidic or oily diluent, so as not to affect the quality of the original product. In the preparation, should be diluted and stirred for 2-3 minutes, if there is no need to dilute, you can directly use group A and B to distribute and stir for 5-10 minutes, lift the stirrer, you can see that the uniform liquid slowly slides from the container is better, at the same time, it should be noted that the opening material should be immediately covered tightly, so as not to solidify and scrap, and the mixture should be prepared and used according to the actual amount. (Note:.)

    When the 991 type is mixed, the first material should be poured into the second material for stirring, which is the opposite of the 911 type and 851 type).

    I saw it on an encyclopedia.

    Group A is alkyd resin, acrylic resin, epoxy resin.

    Component B contains a -NCO group curing agent.

    Example: OH + NCO – NHCOO-

    That is, the group ratio is 1:1

    Depending on the application, the ratio of primer, topcoat, pouring mold, leather, etc. is 1::.

    Polyurethane is a broad category.

    What are you using polyurethane for. There are soft bubbles, hard bubbles, self-cleaning skins, and so on. The ratio of A and B is different depending on the type.

    Summary. Hello dear, happy to answer your <>

    Polyurethane is suitable for water diethyl; Polyurethane is generally not suitable for water diethyl esters. This is because polyurethane and water diethyl ester are different in chemical and physical properties that can lead to incompatibility and reactivity between them. First, polyurethane is usually synthesized by the reaction of isocyanate and polyol, while diethyl water is an organic solvent.

    The chemical properties of these two compounds are quite different, so they may react or be incompatible with each other. Secondly, polyurethane has a low solubility in water, so it can also be difficult to soluble in organic solvents such as water diethyl, leading to incompatibilities between them. Therefore, if polyurethane needs to be used in water diethylyl, it is advisable to conduct sufficient experiments and tests first to determine the compatibility and suitability between them.

    During use, care needs to be taken to prevent possible reactions and safety risks.

Therefore, if polyurethane is required to be used in the water diethyl medium size hand limbs, it is advisable to conduct sufficient experiments and tests to determine their compatibility and suitability with each other.

    During use, care needs to be taken to prevent possible reactions and safety risks. Late life.

    Polyurethane is a polymer material composed of polymeric amino acids and isocyanates. It has excellent mechanical properties, abrasion resistance, chemical resistance and weather resistance, so it is widely used in the manufacture of various materials such as plastics, elastomers, foams, coatings, adhesives and royal chain fiber zhenbisunin.

    Good morning, polyurethane.

    It is a kind of polyurethane commonly known as PU in our Fengqiao.

    It is generally polymerized by polyester polyol and isocyanate to become a rubber-like material with a certain degree of flexibility, and urethane alone is also called ullose, which can be used as another monomer of non-letter socks, polyester and polyslip ether structure. Carbamate and glycolic acid.

    Esters and acrylates are similar to catalytic polymerization to produce hardness solids.

    Polyurethane is the full name of polyurethane compound, also often called PU, urethane is generally a two-component PU paint or ink in the state of the A component (modified polyester polyol), the curing agent is usually isocyanate closed derivatives, please refer to it as appropriate. Polyurethane is the abbreviation of polyurethane, which can be used.
