NQ550 is a two-component water-based epoxy based moisture-proof primer. This product is a fully hydrated system, a green and environmentally friendly product, with breathable performance for wet base construction. This product has strong adhesion to various substrates, especially cement-based substrates.
■ Construction guidance
1. Mixing method: If the total amount of the two components is within 200 grams, they can be manually stirred evenly. If the amount is large, it must be stirred with electricity for about 2-3 minutes until the system reaches a uniform state before adding water to adjust the viscosity. Otherwise, it will affect the coating effect.
2. The construction surface coating must use a fully dry roller, as wet rollers can easily cause discoloration when rolling.
3. The small bucket for component A should not be used to hold mixed paint, otherwise the paint film will become sticky. When using a set of paint for direct mixing, the materials inside the bucket should be scraped clean with a scraper to prevent material loss due to
4. inaccurate mixing ratios. If component B appears cloudy or waxy, it is necessary to heat the material of component B until it becomes transparent, otherwise it may cause problems such as sticking and blackening of the paint film.
■ Limitations
The construction environment should meet the requirements of humidity less than 85%, temperature between 10-40 ℃, ideal temperature between 15-35 ℃, and maintain good ventilation.
■ Storage period
From the date of production, under the requirements of storage conditions, the shelf life of products in their original packaging state is 12 months.
■ Storage conditions
Materials should be stored in a sealed, dry, cool, and well ventilated environment, avoiding high temperatures and sources of ignition. During transportation, the packaging compartment environment is dry and enclosed, and the material stacking is stable.
■ Construction parameters
