Performance advantages:
Easy construction: single component packaging; no mixing is required; no pressurization or heating of power equipment is required; easy to use. It has good chemical compatibility with concrete, asphalt concrete, metal and so on, and the bonding is firm; generally, there is no need for bottom coating treatment.
2. Environmentally friendly: the product does not contain solvents and volatile substances. It is naturally and neutrally solidified at room temperature, does not release toxic substances, does not contain methanol and heavy metals. The product is environmentally friendly, does not pollute water and soil, and does not corrode the bonded substrate.
3.Long service life: excellent long-term weather aging resistance, will not be damaged by the influence of sunlight, rain, snow, ultraviolet light and ozone; it has strong corrosion resistance, acid and alkali resistance, and is resistant to various chemicals. It has a wide pH tolerance range of 2-12.
4. Durability: after curing, it will not become significantly hard or brittle when the temperature is below -60ºC, and can still maintain good elasticity; it does not flow or degrade under the high temperature of +200ºC, and its performance has little change, and its elasticity remains unchanged with good adhesion.
5. Short tack-free time: under normal conditions, the surface is dry for about 30 minutes, which can quickly recover and open the road to traffic.
