Poly-Urea application
Polyurea, an advanced waterproofing and protective coating solution
Polyurea coating technology constitutes a superior system from the traditional ones used in waterproofing and protective coating applications. Its exceptional properties result to fast completion of work and immediate return to service, while making it capable for a wide range of applications, especially under highly demanding conditions.
Polyurea’s technology started back in the 1980s and is becoming extremely popular these days. It is a hot-spray applied membrane based on the reaction of an isocyanate component and an amino or amino-polyol resin in the case of pure and hybrid polyurea respectively. The isocyanate can be of aromatic or aliphatic composition. The combination of the two components takes place in high pressure and temperature.
What are the advantages of polyurea coatings?
- Ultra -fast curing
- Extra ordinary chemical resistance and mechanical properties
- Advance waterproofing properties
- East application and perfect adhesion
- Long working life
FIELD OF APPLICATION
Polyurea is used in a myriad of waterproofing and protection applications, espe cially those where high mechanical and chemical resistance, fast completion of works, and immediate return-to-service are critical considerations, e.g. indus trial, residential, and infrastructure projects, wastewater treatment facilities, water tanks, the automotive industry, and even the ballistic industry.
GRP Lamination
Fiberglass sheet laminating is the process of taking a thin fiberglass sheet and laminating it to another material in order to provide strength and support to that material.
Certain laminating techniques use two steps of applying the epoxy to form resin impregnated fiber glass sheets In the first step there is a resin solvent mixture which is partially cured so it will not redissolve in a second coating of the same mixture. The same resin mixture is subsequently given to the covered fiberglass with moderately cured resin in the second step. This second glaze which covers the first fills in the empty spaces between the fibers. The second coating is also only partially cured. This partial curing of the second layer furthers the curing of the first epoxy layer. This process also produces a thin sticky layer. The first coat ing acts like a sealed insulating sheet, preventing glass fiber contact with con ductive planes. The second coating fills the planes and can form adhesive bonds to cores and conductive layers.
