Amino resin is a kind of synthetic resin with amino groups, usually used in coatings, adhesives, plastics, coatings and other fields. Its main components are formaldehyde and amino compounds, such as urea and melamine. Amino resin has excellent physical and chemical properties, such as hardness, heat resistance, weather resistance, chemical corrosion resistance, wear resistance, etc., and has the characteristics of good coating, coating adhesion and good gloss. Because of its good performance and diverse application characteristics, amino resins are widely used in automobiles, construction, electronics, home furnishing and other fields.

easy way
The following is a brief description of the test methods for common performance parameters of amino resins:
Solid content: heat the amino resin sample to a certain temperature and dry it to a constant weight, and calculate the ratio of the mass of non-volatile substances to the mass of the total sample.
Viscosity: Use a viscometer and other equipment to measure the viscosity of the amino resin solution.
pH value: Use pH meter and other equipment to measure the pH of the amino resin solution to evaluate its stability and application effect.
Solubility: Add the amino resin sample into a specific solvent, shake or stir it and let it stand still, observe the dissolution of the amino resin, and evaluate its solubility.
Density: Use a device such as a densitometer to measure the density of amino resins.
Thermal stability: heat the amino resin sample to a certain temperature, and observe its thermal stability within a certain period of time.
Weather resistance: place the amino resin coating or sample in an outdoor environment, and evaluate its weather resistance after a certain period of time.
Chemical resistance: Expose amino resin coatings or samples to chemicals and evaluate their chemical resistance after a certain period of time.
Hardness: Use a durometer and other equipment to measure the hardness of the amino resin.
Particle size distribution: Use a particle size analyzer and other equipment to measure the particle size distribution of amino resin particles.
Note: Different performance parameters may require different testing methods and equipment, and there may be some industry standards and specifications. For the performance testing of amino resins, corresponding testing methods and standards should be selected according to actual needs. At the same time, strict control of test conditions and standardized operations are required during the experiment to ensure the accuracy and reliability of the test.
