There are more types of potting adhesives if divided according to the raw materials, respectively: silicone potting adhesive, polyurethane potting adhesive, epoxy resin potting adhesive three. Among them, polyurethane potting glue can also be called up potting glue, this glue two-component more common, single-component use rate is relatively low.
What are the characteristics of polyurethane potting adhesive?
1, polyurethane potting adhesive after curing is characterized by low hardness, hardness than silicone potting adhesive hard, but softer than epoxy resin potting adhesive, the strength of this adhesive is moderate, once cured, can show a variety of properties, such as waterproof, moisture, insulation and flame retardant, etc.
2、After curing, polyurethane potting adhesive can play a good role in protection, anti-vibration performance is good, while there is a good anti-corrosion performance.
3, after curing presents a bright film, this film can isolate dust, water into the electrical components, long-term can protect electrical components.
4, polyurethane potting adhesive formula science, cured on a variety of metal, rubber, plastic, and wood materials have good adhesion properties, will not appear corrosion phenomenon.
5, at the same time, this glue can also be used in the harsh environment of electrical appliances, such as wet environment, corrosive environment, once the glue potting to the electrical components, will not be affected by these external factors, can play a very good protection role.
