What is neutral room temperature vulcanized silicone rubber
Neutral room temperature vulcanized silicone rubber is a silicone elastomer that can be cured at room temperature. Its notable feature is that it can be cured in situ at room temperature without heating and pressurization, which is very convenient to use. This material is widely used in adhesives, sealants, protective coatings, potting and molding.
Classification and characteristics
Neutral room temperature vulcanized silicone rubber can be divided into single-component and two-component types according to its packaging method, and can be divided into condensation type and addition type according to the vulcanization mechanism. Single-component room temperature vulcanized silicone rubber relies on moisture in the air to initiate the vulcanization reaction, while two-component condensation type and addition type require catalysts and other chemicals for vulcanization.
Application areas
Neutral room temperature vulcanized silicone rubber is widely used in various industries, including but not limited to:
Adhesives: used for bonding various materials.
Sealants: used for sealing various joints.
Protective coatings: protect surfaces from environmental damage.
Potting materials: used for encapsulation and protection of electronic components.
Moulding materials: used to make molds.
Advantages and Disadvantages
Advantages: Easy to use, no special equipment required, no pollution during curing, suitable for products of various complex shapes.
Disadvantages: The deep curing speed of single-component room temperature vulcanized silicone rubber is slow, while two-component room temperature vulcanized silicone rubber requires precise proportioning and control.
