Specifications material:

• By pulling, the force at which the gap can be from 37 to 60 kg;
• hundred percent hydrophobicity;
• elasticity;
• temperature brittleness of the top layer of the material is 15 degrees;
• He is able to withstand the temperature of 85 degrees for two hours;
• minimum service life of 15 years.

Features liquid waterproofing bit different:

• Withstands temperatures up to 100 degrees;
