  • Q
    What is polyurethane sealant?
    Polyurethane sealant is a high performance elastic sealing material widely used in construction, automobile, electronics, shipbuilding and other industries. It has excellent mechanical properties, weather resistance and bonding properties, and is suitable for a variety of substrates and complex use environments.
Main Features of Polyurethane Sealant
  • 1. Excellent Elasticity

  • Polyurethane sealant has good elasticity and elongation, and can adapt to the deformation and thermal expansion and contraction of the substrate.

  • 2. Excellent Adhesion

  • Polyurethane sealant can provide strong adhesion to a variety of substrates such as metal, glass, wood, concrete, etc.

  • 3. Good Weather Resistance

  • Polyurethane sealant has excellent UV resistance, ozone resistance and chemical corrosion resistance, suitable for long-term exposure to outdoor environments.

  • 4. Water Resistance and Moisture Resistance

  • Maintain good performance in humid environments and underwater conditions.

  • 5. Low Shrinkage

  • Polyurethance sealant has low shrinkage after curing, and will not cause stress concentration and cracking of the substrate.

JCT Machinery Double Planetary Mixer

JCT Machinery's double planetary mixer is an ideal equipment for producing polyurethane sealant. Its unique stirring principle and efficient mixing ability make it play a key role in the production process of polyurethane sealant.

Features and Advantages of JCT Machinery Double Planetary Mixer
  • 1. Efficient Mixing

  • The stirring paddle of double planetary mixier revolves around the mixing tank while rotating, which can fully mix the materials without dead corners and ensure that the materials are evenly dispersed.

  • 2. Handling High-viscosity Materials

  • Double planetary mixer is particularly suitable for high-viscosity, high-solids materials, and can provide strong shear and extrusion forces.

  • 3. Temperature Control

  • Equipped with heating or cooling jackets, it can control the temperature of the matterials during mixing and ensure that the reaction is carried out at an appropriate temperature.

  • 4. Vacuum Function

  • Planetary mixers can usually be operated under vacuum to remove bubbles in the mixture and improve the density and performance of the product.

  • 5. Versatility

  • Not only can it mix and knead, but it can also perform a variety of operations such as dispersion and degassing.
