Hot joint sealant

Description

Hot joint sealant

Hot joint sealant is an elastic sealant based on modified bitumen rubber, which is used to fill the expansion seams and horizontal junctures and has no harmful effect on drinking water.

Hot-applied mastic is a flexible and durable joint sealant based on modified bitumen (asphalt) with rubber additives, designed to fill expansion joints, horizontal joints, and gaps between concrete sections in large floors. This product is applied hot, and once it cools and dries, it forms a resilient and flexible layer that withstands temperature changes and environmental stresses. Due to its bituminous structure and elastic properties, hot-applied mastic prevents cracking, water infiltration, and damage to concrete joints.

Features Hot joint sealant

1. High Flexibility and Elasticity:
   • Due to the use of rubber materials and modified bitumen, hot-applied mastic retains its elasticity after drying, allowing it to resist expansion and contraction caused by temperature changes and pressure. This makes it ideal for large concrete floors and structures that are subject to repeated stresses.
2. Water and Moisture Resistance:
   • The bituminous base of hot-applied mastic makes it impermeable to water and moisture. As a result, this mastic is used in floors that are continuously exposed to water and humidity or in outdoor spaces.
3. Resistance to Microorganism Growth:
   • This product is highly resistant to the growth of bacteria, algae, and aquatic microorganisms, making it a suitable option for use in aquatic structures and humid environments.
4. Cost-Effectiveness and Ease of Application:
   • Compared to other flexible sealants, such as polyurethane mastics, hot-applied mastic is more affordable and easier to apply. Its ability to be heated and easy application process make it very cost-effective in terms of time and expense.
5. Resistance to Weather and Thermal Conditions:
   • This type of mastic can withstand temperature changes and various weather conditions without cracking or peeling. Therefore, it is an excellent choice for flooring in outdoor environments exposed to sunlight, rain, and temperature fluctuations.
