Polyaspartic Mixing Ratios
The matching is not based on empirical estimates, but is based on item-by-item control from size, mixing, environment, equipment to time of use. Specific ratios and operational times are always based on the corresponding product conformity certificate and technical information.
The matching is not based on empirical estimates, but is based on item-by-item control from size, mixing, environment, equipment to time of use. The following parameters apply to common double-assembly polyaspartic polyurea field operations; Specific ratios and operational times are always based on the corresponding product conformity certificate and technical information.
Standard matching requirements
A:B=1: 1 weight ratio, part custom system 2: 1. The product conformity certificate and technical information must be checked prior to construction, and electronic scales must be used throughout the process in terms of weight, not in terms of the naked eye, nor in terms of volume estimates.
Regulate the mixing process
Premix component A to redisperse any settling, then add component B at the approved ratio. Mix at low speed for 2–3 minutes until the color is uniform and no particles, separation or lumps remain. Avoid high-speed mixing that entrains air and causes pinholes or bubbles.
Construction environment conditions
Apply at 5–35°C, preferably 15–25°C for consistent handling. Relative humidity should not exceed 85%, and the substrate should be at least 3°C above the dew point. Do not mix or apply outdoors in rain, snow, heavy fog or high humidity, which may cause blistering, delamination or tackiness.
Container requirements for appliances
Drums, mixers and construction tools should be kept clean, dry, oil-free, impurities and residues. Different brands, different models of material are used separately to avoid cross-pollution and curing anomalies; Dust management is done simultaneously around unsolidated coatings.
Supply control
It's only a few times. The hybrid operation time at 25℃ is normally approximately 40 minutes; Over 30℃ shall be controlled within minutes of 30; 5 - The temperature of 10℃ may be extended, as appropriate, up to a maximum of 2 hours. Work is suspended as soon as denseness, blocks or coagulation occurs and no further work can be done with water.
Selection guide
(a) A and B components of a double set of polyaspartic polyurea shall be measured and fully mixed in accordance with the corresponding product requirements and be compatible with non-stop product applications; It is also necessary to control the purity of the equipment, environmental conditions and the time spent on the mix.
