Detailed Dynamic Double Units Polyurethane Waterproof Coating() Description
Main Technical Capacity Index (Performance Chinese Standard
GB / T19250 - )
The double unit polyurethane waterproof coating is a kind of reactive
and elastic coating. The accessory ingredients include
activator and thinner FBX - 02, aging resistance solvent. The formed material is the polyether polybasic
alcohol and the condensation - polymerized polyurethane performed polymer
of the isocyanine end capping. When using, we
lay the double units' polyurethane waterproof coating on the
waterproof foundation; the performed polymer of the isocyanine end
capping (A ) and the diamine, solidify to be elastic membrane, the polybasic alcohol of B group
crosslinked react, then it has a
waterproofing function. The product includes a black asphalt base polyurethane waterproof coating and a colored asphalt base
polyurethane waterproof coating.
Product Characteristics
The double units' polyurethane waterproof coating is a kind of
reactive elastic coating. The membrane is waterproof, elastic,
with a great extension degree and erosion resistance; it can firmly conglutinate with the foundation.
Construction Standard
The colored asphalt base polyurethane waterproof coating also has the
advantage of bright color and fine integrated function. The service life of the product is
twenty - five years. The product
can be widely used in the construction roofing, the toilet, the
underground engineering as the waterproof and seal material. The liquid cold construction can form a large
area of waterproof membrane without gaps. It can
also used in the underground pipes as the waterproof and erosion
resistance material. The curing speed is
relevant to the temperature, the humidity and the airiness conditions. Foundation processing: the waterproof foundation should be level, solid and dry (water content is ≤9%),
without dust, or grease.
We should strictly measure according to the proportion in the
specification, evenly blend, otherwise the membrane curing would be
affected and cause an accident. We should flatten the uneven place and the
cracks by the grouting mortar.
Items for Attention
According to the specific proportion (weight ), blend the A
group with the B group. The pipe, the
ground leakage should be firmly set, sanitary equipment, the joining opening should be
sealed, and the end should be pliable without looseness. The brushing thickness should be identical to
the designed thickness; generally we brush three times. The protective layer is used in the toilet
and bathroom to increase the adhesive strength of the waterproof
membrane and the protective layer. The outside
of the roofing can be brushed with the protective coating to resist
heat and prolong its life. Before the last membrane finishes
curing, scatter clean sand particle (2mm ) on its dry surface;
after the membrane that is adhered with sand is cured, we can begin the protective layer construction. The suggestion usage amount is 1. Before doing the underground waterproof protective layer, the insulation layer should be made to protect the
membrane.5~2.5kg / m2.
The construction site should be airy; the temperature is usually above
zero centigrade; we must not construct in the rain. □ A and B material
should be used in time, the blending material must be used before it
sets, or it will be wasted.
If the curing of the membrane is too slow, we can add proper gelling
promoter, but the usage amount should not be more than 0. The cured coating should not be used again.3 percent of
A group. The
used tools and vessels should be washed after use. It the curing is too quick, we can use a gelling inhibitor,
and the amount should not be more than 0.5 percent of the A group. We should pay
attention to fire prevention on the construction site.
