What are the different types of water -based adhesive?
Water -based adhesive, which is categorized in one of the following four categories: vegetable adhesives, resin cements, animal or proteins and latex cements. Each of the different types has its own properties. Depending on the formulation, the adhesive may lead to a hard resin or sticky film finish. In general, water -based adhesive is without solvent, so it is safe for use in tight neighborhoods and areas that may not be well ventilated, such as classrooms. The most popular water -based adhesive is white adhesive or wood glue.
Vegetable adhesive is a common type of water -based adhesive. These adhesives have a starch base and a brittle surface. This water -based adhesive commonly used to bind books has a brown color and a reputation of a long -term paper bond. The vegetable -based adhesive is more likely to disintegrate when it is exposed to water. Rezin cements are emulsions, a mixture of liquids that cannot be mixed. Sresin cements, polymers, howO is ethelyne vinylcetate (EVA) or polyvinylace (PVA), are emulsified and placed in water that acts as a carrier. While resin cements are white when they are wet, dry clean and are relatively flexible. Rezin cements are useful for gluing some plastics, paper and wood.
Animal and proteins are also used to produce water -based adhesives. These adhesives use either animal parts processed mainly for the production of hot animal adhesive or animal milk, which is used to produce casein adhesive. The glue for a hot animal is used at 140 ° F (about 60 ° C) and is brown. This water -based adhesive is used when a quick application is required. Casein adhesive is used to indicate bottles of wine and beer due to its resistance to moisture.
Latex cements consist of emulsified elastomers. These water -based adhesives are generally white and usually jSOU listed one part and holidays to dry. Depending on the formulation, the adhesive may remain sticky or dry into a strong bond. Latex cements are often used for separate envelopes and stamps, they are also used to bind to fabric and leather goods.
The primary advantage of using water -based adhesive without solvent is the removal of volatile and flammable materials. This reduces the risk of fire and explosion, especially during the production process and industrial adhesives. Removing solvents in the adhesive will also reduce the adhesive toxicity; However, water -based adhesives create more waste water and use more energy than a solvent -based counterpart. Deciding on the most useful adhesive for a particular use requires careful consideration of the benefits and limitation of all available adhesives.
