Product Introduction
LY-4202 is aromatic polyurea coating of 100% solid content; component A isisocyanate, and component B ispolyether. The product is designed for waterproof, protective, anti-corrosion, and wear-resistant occasions, and implements GB/T23446-2009 national standard indicators.
LY-4202 is suitable for construction using heated two-component equipment to realize rapid coating forming without any solvent. LY-4202 can quickly gel and can be applied in high humidity areas without worrying about blister or holes.
Basic Use
LY-4202 is designed for the waterproofing of horizontal or vertical substrates of various buildings, including roof waterproofing and underground waterproofing. It is widely used for primed steel, concrete, wood, glass fiber and foam substrates. Through construction, LY-4202 can make the rough surface reach the anti-slip effect. In areas where color stability is the main requirement, UV-resistant aliphatic topcoats must be used.
