[Asia Economy Reporter Kim Jong-hwa] KCC has launched 'SpotanSEAL,' a urethane-based sealant product that can be used as a waterproof sealing material.

SpotanSEAL is a sealing material that fills cracks occurring in concrete or joints between concrete during rooftop waterproofing work. In particular, this product is a urethane-based sealant, which ensures good compatibility since the main component of waterproofing materials is urethane resin.

Concrete that forms rooftop floors tends to develop cracks over time when exposed to external environments. Additionally, concrete expands and contracts due to temperature and humidity changes, so joints are installed at regular intervals to accommodate these movements. If waterproofing is performed with cracks and joints left untreated, it is difficult to achieve a smooth coating surface, reducing waterproofing effectiveness. Therefore, a compatible filling material is necessary.

Urethane resin has excellent elasticity and film strength, making cracks less likely to occur and allowing seamless finishing to prevent leaks. Waterproofing materials applied on rooftops must prevent cracking caused by outdoor exposure and provide waterproofing against rainfall, so paints containing urethane resin are used. Since SpotanSEAL also primarily contains urethane resin, it has excellent elasticity and can eliminate seams in the filled areas.

A KCC official stated, "Rooftop waterproofing coating work is frequently performed not only on new buildings but also periodically on existing structures, so demand is high," adding, "SpotanSEAL effectively fills cracked or jointed areas and is well suited for use with our urethane waterproofing materials like Spotan."
