5 Test methods
5.1 Sampling
The product is sampled, according to the provisions of GB/T 3186, OR it can be
sampled according to the agreed method. The sampling amount is determined,
according to the inspection needs.
5.2 Test environment
The state adjustment of the test panel and the temperature and humidity of the test shall
comply with the provisions of GB/T 9278.
5.3 Preparation of test template
5.3.1 Substrate and substrate treatment
Use glass plates for curing performance, gloss, pencil hardness; use aluminum plates or
glass plates for wear resistance item; use white exterior porcelain tiles for yellowing
resistance item; use light-colored veneer plywood for other items (in compliance with
the technical requirements in GB/T 15104-2006). The requirements and treatment of
glass plates and aluminum plates shall meet the requirements of GB/T 9271. The
requirements of white exterior porcelain tiles shall meet the requirements of 6.1 in GB/T
23983-2009. The light-colored veneer plywood shall be placed for over 7 d, under the
conditions of 5.2, before use.
Note: Light-colored veneer plywood can use light-colored varieties, such as unstreamed beech,
white maple, white oak; the plywood shall be guaranteed not to deform during the test.
5.3.2 Requirements for plate making
Generally, a wire rod coater is used for plate coating. After agreement, it can also be
coated, by shower coating, roller coating, spray coating, brush coating, etc. The wire
rod, which has a specification of 40, is used for single coating; the wire rod, which has
a specification of 20, is used for the composite coating. Please refer to Table 2 for the
plate making requirements of each item. The conditions of UV curing shall be indicated
Open the container. Use a spatula or stirring rod to mix. It allows sedimentation at the
bottom of the container. If it is easy to mix evenly after stirring, it is rated as "even
without lumps after stirring".
Note: For multi-component coatings, the main agent and curing agent shall be inspected
separately.
5.4.3 Fineness
Carry out according to the provisions of GB/T 6753.1-2007.
Note: For multi-component coatings, the main agent and curing agent shall be inspected
separately.
5.4.4 Storage stability
Put about 0.5 L of the sample into a well-sealed iron can, which has about 10% space
left in the can. Put it in a constant temperature drying box at (50 ± 2) °C, after sealing.
Take it out after 7 days. Place it at (23 ± 2) °C for 3 hours. Check the "state in the
container", according to 5.4.2. If there is no significant difference between the test
results after storage and before storage, it is rated as "no abnormality".
Note: For multi-component coatings, the main agent and curing agent shall be inspected
separately.
5.4.5 Curing properties
It can be measured, by a single UV lamp or a UV curing device in the production line.
The measurement unit of curing performance is mJ/cm2 (tested by a UV energy meter).
The determination of curing property is carried out, in accordance with the provisions
of Method A of actual dry of GB/T 1728-1979. Under the curing conditions agreed by
both parties, if the paint film can be dried, it will be judged as "pass".
5.4.6 Appearance of coating film
Visually observe the template, under scattered sunlight. If the coating film is uniform,
AND there is no coating film damages such as sagging, blooming, pinholes, cracking,
peeling, it is rated as "normal".
5.4.7 Grindability
Use 400# water sandpaper to carry out 10 dry grindings (one reciprocating counts as
one grinding). If the painting film is easy to be ground into smooth surface, it is rated
as "easy grinding".
5.4.8 Gloss (60°)
It is carried out, according to the provisions of GB/T 9754-2007.
5.4.9 Abrasion resistance
It is carried out, according to the provisions of GB/T 1768-2006. The model of grinding
wheel used is CS-10.
Note: Other rubber grinding wheels, which have comparable abrasive action to CS-10, can also
be used.
5.4.10 Pencil hardness
It is carried out, according to the provisions of GB/T 6739-2006. The pencil is a Chinese
brand 101 drawing pencil.
5.4.11 Cross-cut test
It is carried out, according to the provisions of GB/T 9286-1998. The grid spacing is 2
mm.
5.4.12 Dry heat resistance
It is carried out, according to the provisions of GB/T 4893.3-2005. The test temperature
is (90 ± 2) °C. The test time is 15 min.
5.4.13 Water resistance
It is carried out, according to the provisions of GB/T 4893.1-2005. The test solution is
distilled water. The middle part of each plate is taken as the test area. Respectively place
five layers of filter paper, on each test area. The filter paper shall be kept moist, during
the test. If necessary, apply Vaseline to the contact portion between the glass cover and
the test panel, to seal it. After 24 hours, remove the filter paper. Absorb it dry. Let it
stand for 2 h. Visually observe it under scattered sunlight. If 2 of the 3 test panels do
not have any film damage, such as blistering, cracking, peeling, etc., but slight
discoloration and slight gloss change are allowed, it is rated as "no abnormality". If the
above film damage occurs, it shall be described according to GB/T 1766.
5.4.14 Alkali resistance
The test and result evaluation method is the same as that of water resistance. The test
solution is 50 g/L Na2CO3 solution; the test duration is 2 h; it is observed, after being
placed for 1 h after test.
5.4.15 Alcohol resistance
The test and result evaluation method is the same as that of water resistance. The test
solution is 70% (volume fraction) ethanol aqueous solution; the test time is 8 h. It is
observed, after being placed for 1 h after test.
