Application of Glycidyl Methacrylate GMA in Non-woven Fabric Coatings

GMA is a cross-linking monomer that can be used in non-woven fabric adhesives.

GMA is also used in the field of adhesives and non-woven fabrics. For example, when used in acrylic emulsions, it can improve the adhesion to metals, glass, cement, polyvinyl fluoride, etc. For non-woven fabrics with synthetic latex, GMA can improve its washability without affecting the feel.

I. Environmental performance requirements

1. Low VOC content: VOC is the abbreviation of volatile organic compounds, which refers to a low-boiling organic compound that evaporates in the air and pollutes the atmospheric environment. my country already has VOC emission standards. In order to meet national environmental protection standards, the VOC content of non-woven fabric spray-coated environmentally friendly coatings should not exceed the national standard value.

2. No heavy metals: Heavy metals are pollutants that are harmful to both the environment and human health. Therefore, non-woven fabric spray-coated environmentally friendly coatings should not contain any heavy metals, which is also one of the basic requirements for environmentally friendly coatings.

2. Color uniformity requirements

Non-woven fabric spray-coated environmentally friendly coatings need to have good color uniformity after spraying, that is, there should be no problem of excessive color difference. In order to ensure color uniformity, the composition of the coating should be scientifically proportioned, high-precision and high-stability control is required during the production process, and the product storage conditions must also meet the requirements.

3. Viscosity requirements

The viscosity and fluidity of the coating also have a great impact on the quality of spraying. A good coating should have appropriate viscosity, be able to achieve good fluidity, and ensure the operability during the spraying process and the quality of the finished product. What needs to be noted during use is that the viscosity required for spraying equipment of different brands and specifications is different, and it needs to be adjusted according to actual conditions.
