需要防涂鸦助剂吗？　化学成分为含羟基聚二甲基硅氧烷（羟基含量1.3％）

cnlyk

德固赛有防涂鸦树脂，效果还可以

涛声

Tego有个助剂加了还是挺有用的，就是在哑光里用起来效果不行，表面会发花。
请问各位有什么好的助剂或树脂推荐？用在哑光、亮光漆里的。

直接找BYK的经销商，他们那里有这样的助剂，不过添加量很高，成本贵，这种油漆修补很困难，做不好层间没有一点附着力，水刷在立面的玻璃上一样，有一定技术含量。

看来很多是通过助剂技术来实现

小谭

表面效果是用黑色大头笔画上去用布一擦就能去除。
直接用德固赛的一只树脂加氨基做成烤漆就可以了。
上海元邦也有一只可以，且价格比德固赛的便宜，遗憾的是树脂色数太深，不适合做白色。

国家正在制定相关防涂鸦涂料的标准，不知道在水性这一块前景如何

FPU® “Anti-Graffi ti” Fluorinated Polyurethane 51PC101™
PRODUCT DESCRIPTION
51PC101TM is a high-performance, highly fl uorinated polyurethane top coat formulated for thin fi lm
applications, offering general ease of handling and application. It is a two-component, solvent
based, high solids enamel system which exhibits outstanding performance properties, compared to
higher build, multi-coat premium systems.
The patented “fl uoroshield” protection of 51PC101TM makes it virtually impervious to moisture and
oxygen permeation. 51PC101TM exhibits unsurpassed performance for all physical properties as
well as resistance to chemicals, weathering and uv degradation. 51PC101TM contains a special
“anti-graffi ti” feature making it resistant to graffi ti attack.
CHARACTERISTICS
A high performance, inert topcoat system designed to overcoat virtually any surface and make it resistant to corrosion, UV
breakdown, abrasion, graffi ti and chemical attack. FPU® coatings exhibit outstanding weathering characteristics. Developed
over two decades of research and development, FPU® has a proven service history.
51PC101TM is ideal for limited immersion service on marine, aerospace, architectural, industrial and automotive equipment,
ferrous and non-ferrous metals, masonry, timber, fi berglass and carbon fi ber. It provides a high quality fi nish, and offers
exceptional all round performance with an expected life span exceeding 20 years.
􀀻 Outstanding Hydrophobic and Oleophobic surface properties
􀀻 Impervious to moisture and oxygen permeation (Osmotic barrier)
􀀻 Highly fl exible and outstanding impact and abrasion resistance
􀀻 Low surface energy which resists soiling and marking
􀀻 Highly resistant to attack by hydrocarbons and chemical products
􀀻 Completely insensitive to UV radiation
􀀻 Highly resistant to graffi ti attack from spray paint and marker
Application
For optimum appearance properties, 51PC101™ should be spray applied in two to three coats to a minimum of 2 mils DFT / 50
microns DFT. Always allow each coat to “fl ash off” to a tacked state prior to a following coat.
51PC101™ may also be spray applied, brushed or rolled in one coat, unreduced to the recommended DFT.
FPU® coatings must not be applied to surfaces at ambient temperatures above 350C / 950F. For optimum application
properties, the temperature of the material should be between 100C and 250C / 500F and 800F prior to mixing and application.
Apply the coating only when the surface temperature is more than 50F or 30C above the dew point temperature of the
surrounding air and relative humidity is below 85%, in order to prevent moisture condensation on the surface.
Mixing & Activation
Mixing ratio 2:1 by volume (2 parts base to 1 part activator)
Activator: 51AC100
Reduction: 00TR102 - Slow reducer
00TR100 - Fast reducer
Spray Viscosity: 21-25 seconds #2 Zahn
51PC101 is a two component coating system supplied in two separate containers. Part A is the base and Part B is the
activator. Prior to activation, Base component (Part A) must be thoroughly mixed by mechanical agitation. Following agitation,
with a paint stick, ensure all settled material is removed from the can bottom. After activation of Component A and Component
B together, agitate for approximately 1-2 minutes. Reduce activated 51PC101 to a maximum of 15% if required with
recommended reducer and use immediately. 51PC101 requires no induction period.

Surface Preparation
Suitable substrates for 51PC101TM include ferrous metal, galvanized metal, aluminum, fi berglass, carbon fi ber, concrete and
wood. Good surface preparation and cleaning of all substrates to be coated is essential for optimum performance of the
coating system. All surfaces to be coated should be clean, dry and free from contaminants. For old or previously fi nished
sur fac es, the degree of preparation and cleaning required, is dependent upon the condition of the substrate.
Consult your 21st Century Coatings (Canada) Ltd. representative for recommended surface preparation procedures for your
specifi c project.

加氨基做成烤漆就可以吗

cdz19840125

这个啊，好像用双组分做效果不错。

有的施工条件不允许怎么办？
要常温干燥的。

zhyljq2002

感觉这块的市场还是不错的，关键是要把成本降下来。

叶工

用水性记号笔做的防涂鸦测试难度不大，大的是用溶剂性记号笔做防涂鸦测试的难度就大了，特别是做哑光清漆。现在水性漆只能做到用水性记号笔测试的，但用溶剂性记号笔测试的目前为止本人还没听过和见过。

kevinfc

用SILOK的3390可以做到，但流平性和透明性会受影响。

anny725

不知有稳定的这块树脂和助剂没有，做双组份产品！有与我联系！
