Type for vertical or irregular surface
construction: HC804V
Sprayable types: HC804S, HC804VS
PRODUCT FEATURE
1. Single-component, moisture-curing: Ready
for brushing after opening the package; suitable for coating on vertical and
irregular surfaces; easy to construct.
2. Free of isocyanate compounds, organic
solvents, and volatile plasticizers.
3. Low odor, low VOC, formaldehyde-free,
and no hazard labels.
4. Excellent adhesion to most substrates
without the need for a primer.
5. Low requirement for substrate treatment:
Can be constructed on damp substrates, as well as on new or old concrete
surfaces.
6. Water-resistant immediately after
surface drying: No impact on waterproof performance when exposed to water;
excellent early water spray resistance.
7. After curing: Smooth surface, high
elasticity, high wear resistance, high slip resistance, and excellent weather
resistance.
8. For rusted steel surfaces: No rust
removal required; direct brushing to achieve rust prevention and inhibition.
9. Multiple color options: Colorless
transparent, multiple colored transparent, and multiple opaque colors
available.
10. No substrate contamination: Good coat
ability, excellent adhesion compatibility with various coatings, and no coating
contamination after application.
11. Additional functional coatings (e.g.,
anti-slip layers, anti-graffiti layers) can be applied on top of the cured
coating.
12.
Hydrophobic
surface with rainwater self-cleaning effect.
TYPICAL APPLICATION
1. Suitable for exposed roof waterproofing
(suitable for new and old color steel tiles, concrete substrates),
2. It is especially suitable for roof
renovation and repair of factory buildings in chemical industrial parks and
coastal industrial parks.
3.
Suitable for
anticorrosion and rust prevention on outdoor chemical pipelines and tank
surfaces,
PHYSICAL PROPERTIES
Note: Conditioning,
specimen is conditioned under (23±2) ºC, (50±5)% relative humidity if not
specified.
CONSTRUCTION
METHOD
1.
Substrate Preparation: a) Inspect the construction substrate before
construction to ensure it is flat, firm, and free of looseness. b) Clean the
substrate: Ensure no standing water, keep it clean, and free of particles,
loose materials, oil, and other impurities. c) If the substrate has grooves or
gaps deeper than 2 mm, fill and level them with putty, joint filler, or sealant
first. For floors, it is recommended to use liquid leak-stopping waterproof
liquid for grouting first. d) For rusted steel surfaces:If corrosion is
severe (surface bulging, peeling, or heavy slag), first use a scraper or wire
brush to remove surface slag and peeling layers, then blow off floating dust
with compressed air (>6 kg pressure) before brushing, rolling, or spraying
the coating. If corrosion is mild (only surface rust or pitting rust), directly
blow off floating dust with compressed air before coating. e) If the surface
has oil stains or raw material residues, perform oil removal treatment. After
oil removal, it is recommended to apply a primer (Primer E01) to isolate oil
stains; strictly follow the primer construction specifications for application.
f) If the coating substrate has wide gaps (e.g., ≥2 mm), first fill and seal them with
MS sealant (FM Series), and wait for the sealant to cure before coating.
2.
Product
Inspection and Tool Preparation: a) Ensure the product packaging is intact and
within the validity period. b) Confirm the bonded materials and the
construction environment (temperature and humidity must meet the product usage
conditions). c) Calculate the coating area and use an appropriate amount of
waterproof coating based on a thickness of 1~2 mm.
3.
Peripheral
Protection: a) Block the surroundings of drains and gutters to prevent coating
from flowing in and causing blockages. b) Use masking tape to protect areas
that need shielding.
4.
Coating Application: a) Apply the single-component solvent-free
moisture-curing anticorrosive coating evenly; control the construction
thickness at approximately 1.0~2.0 mm. Avoid air bubbles during application. b)
If applying multiple coats, ensure the interval between each coat does not
exceed 48 hours to prevent delamination.
5.
Curing and
Maintenance: a) After construction, avoid foreign objects splashing onto the
surface of the single-component solvent-free moisture-curing anticorrosive
coating. b) Under standard conditions (23℃, 50%
relative humidity), the coating can be stepped on after 24 hours of curing and
maintenance, and can be used normally after 3 days.
6.
On-Site
Cleaning: a) Wipe off spilled coating immediately with anhydrous ethanol. b)
Tear off the protective tape in time and clean up excess adhesive. c) Set up
isolation belts or place construction signs, etc.
1.
For
Single-Component Solvent-Free Moisture-Curing Anticorrosive Coating:
2.
Use the
coating as soon as possible after opening the package to avoid prolonged
exposure.
3.
Due to the
diversity of substrates, it is recommended to conduct an adhesion test before
using the coating on special substrates.
4.
Construct in
the order of "corners first, then flat surfaces; vertical surfaces first,
then flat surfaces".
5.
During
construction, the coating tends to accumulate in corners and joints; pay
attention to controlling the construction thickness.
6.
For roller
coating, it is recommended to use a short-haired roller or a sponge roller to
reduce air bubbles.
7.
For brush
coating, clean off loose hairs from the brush before use.
8.
Keep the
area well-ventilated after construction; do not step on the coating until it is
completely cured.
9.
Do not use
protective tape with a silicone-coated surface.
10.
If spraying
additional coating on the surface, wait for more than 24 hours after applying
the waterproof coating and ensure the waterproof coating has hardened before
application. Conduct a compatibility test before coating.
11.
If applying
a second anti-slip layer or anti-graffiti layer on the cured waterproof coating
for floors, wait for 12 hours; if the coating is used during this period, clean
it first before applying the anti-slip or anti-graffiti layer.
