Which polyurethane foam hardens the fastest

Relatively recently appeared on the market mounting foam, its versatility has won great popularity among builders. Ease of use in sealing cracks is so great that it replaced a mineral wool, cement plaster. Fast hardening and readiness for use is the main victorious indicator of the displacement of other materials during construction.

It is not surprising that many manufacturers and types of polyurethane mounting appeared on the market. General characteristics are similar, but it is not easy to choose with instant hardening. It directly depends on the quality of the purchased goods. Given the saturation of the market with a low-quality product, the choice becomes a difficult problem. First, let's figure out what hardening depends on.

Solidification time

This stuff is not easy. The degree of solidification of polyurethane depends on several factors that are directly relevant to its full readiness. Depends on:

1. Ambient temperatures - operating range from +5 to + 30 ° C. Practice has proved that it has an ideal working temperature of + 20 ° C.

2. The temperature of the cylinder with foam - during operation must be at least
3. Humidity is the main condition for accelerated solidification. Ideal humidity of at least 80%. If less, setting time increases.
4. Qualities - high-quality polymer under adverse conditions, gives a low result.

Under normal conditions, a good polymer sets in three hours. Final solidification lasts from six to twelve hours. To accelerate the hardening process is quite possible. It is necessary to moisten the polymer with any available method. Instant solidification depends on the application.

In-use polymers

Among professional builders, the polymers of the following manufacturers are most in demand:

1. Profflexprogold - Due to its high productivity, builders are in high demand. Temperature operating mode: from +5 to + 35 ° C. Fast hardening of polyurethane was noted, two hours is enough. Users note cost-effectiveness and good composition density
2. Installation time is a big plus of the product, relatively low price, good properties. Excellent adhesion to a variety of building coatings is noted. By cons, a lot of fakes.
3. Soudal - excellent adhesion, good density after solidification, excellent insulating qualities. Cons: high sensitivity to sunlight, destroying insulation.
4. Makroflexstandart - is in high demand in the countries of the former USSR. High resistance to temperature changes, adhesion at a high level, fairly quick hardening, good insulating qualities. Cons: there is a high probability of fake, noticeable shrinkage after drying.

The list includes the most popular products with an excellent degree of properties and fast hardening.
