Question 6

What advantage and shortage of polyurethane (pu) waterproof coating is?

Accepted Answer

Advantages
Excellent elasticity and elongation
High tensile strength and tear resistance
Good chemical resistance
Long service life under normal conditions
Mature technology, widely available

Disadvantages
Poor UV resistance; yellows and degrades when exposed
Moisture-sensitive during application; substrate must be dry
Solvent-based versions have high VOC and odor
Can be tricky to achieve uniform thickness on site

Question 7

What advantage and shortage of MS (Modified Silicone) Polymer Waterproofing Coating is?

Accepted Answer

Advantages
Excellent UV and weather resistance
No isocyanates, no solvents, very low VOC
Good elasticity even at low temperatures
Strong adhesion to various substrates without primer
No carbon dioxide foaming issue (unlike PU on moist substrate)
Fast cure; can be applied in single coat in some systems

Disadvantages
Generally higher cost than acrylic and some PU products
Less mechanically strong than polyurethane/polyurea
Market availability more limited than PU or acrylic

Question 8

What advantage and shortage of Acrylic Waterproofing Coating is?

Accepted Answer

Advantages
Water-based, low odor, low VOC, environmentally friendly
Excellent UV resistance; maintains color and sheen
Easy to apply (brush, roller, or spray)
Cost-effective
Good breathability

Disadvantages
Poor resistance to ponding water
Can become brittle over time
Lower elasticity compared to PU, MS, and polyurea
Cannot be applied at low temperatures (below ~10 degree)
Limited chemical resistance

Question 9

What advantage and shortage of Polyurea Waterproofing Coating is?

Accepted Answer

Advantages
Extremely fast curing 
Excellent moisture tolerance; can be applied on slightly damp substrates
Superior mechanical properties: high tensile, tear, and abrasion resistance
Outstanding chemical and thermal resistance
Excellent UV stability (aliphatic systems)
Very long service life (20 to 30+ years)

Disadvantages
High material cost
Requires specialized high-pressure spray equipment
High application skill required; errors are hard to correct due to fast cure

Question 10

What construction adhesive sealant we can supply for vertical surface and what application?

Accepted Answer

1, MS (Modified Silicone) Polymer Sealant:
Window and door perimeter joints that require subsequent painting
Multi-substrate bonding: stone, concrete, metal, wood, plastics
Low-odor indoor sealing applications
Prefabricated building panel joints
Sanitary and wet-area sealing (non-mold grades available)
2, Polyurethane (PU) Sealant:
Floor expansion joints, parking decks, walkways
Precast concrete panel joints
Bridge and retaining wall joints
Basement and pipe system sealing

Question 11

What advantage and shortage of polyurethane (pu) adhesive sealant is?

Accepted Answer

Advantages
Highest mechanical strength, abrasion resistance, and tear resistance
Strong adhesion to concrete, metal, and other substrates
Paintable
Tolerates slightly damp substrates (moisture-curing)
Good flexibility

Disadvantages
Poor UV resistance; chalks and yellows when exposed outdoors without protection
Must be top-coated for long-term outdoor exposure
Many products contain isocyanates; ventilation and PPE required
Cure speed depends on humidity
Can be difficult to clean up before curing

Question 12

What advantage and shortage of MS (Modified Silicone) Polymer adhesive sealant is?

Accepted Answer

Advantages
Paintable
Primerless adhesion to most substrates
Does not stain natural stone
Low odor, solvent-free, isocyanate-free, environmentally friendly
Good UV and weather resistance
Good elasticity and movement capability

Disadvantages
Not as good as dedicated silicone for extreme UV exposure or high-movement structural glazing
Generally higher cost than acrylic sealants
Market availability may be more limited than silicone
